Koi fish are popular for their incredibly ornate and colorful bodies, and are bred throughout the world today.
Koi are similar to carp except for their colorful designs and patterns
that are their main attraction in many man-made ponds.
Watching a school of colorful Koi and their graceful movements is a
great way to relax and relieve yourself from stress.
Some Koi have the ability to change colors. One among them is the black Koi
These fish are similar to their colored mates, except for their dark, bronze color.
They are easy to distinguish when they change color and grow several shades lighter.
The streamlined shape of black Koi fish makes them look menacing
amongst the other colorful fish in a Koi pond and have earned the nickname ‘shadow of the rainbow’.
They are almost unnoticeable when they disappear in the shallow
depths of a Koi pond since most of these ponds have dark linings.
Like regular carp, Koi are known to live for several years, with an average life span of around 30 years or more.
Like some of the other Koi, black koi fish change color due to their
diet or significant changes in the temperature of the water.
Most black Koi fish are bred in Asia in countries such as Japan,
Indonesia, China, and Malaysia, from where they are distributed to other parts of the world.
High quality black Koi are known to grow up to three feet.
A favorable pond for black Koi would need to hold over thousand gallons of water.
Fine gravel, rocks, and hardy plants are ideal additions to a Koi pond.
The base of the plants must be firmly secured with large rocks in order to protect the Koi from uprooting them.
A filtration system is also essential to maintain proper water conditions.
Black Koi fish need to be fed on flake food or pellets of a high quality.
Once they are well acquainted with you they will slowly learn to eat from your hand.
Male fish are distinguishable by the breeding spots visible on their
head and a concave anal section.
A single spawn can result in over a thousand eggs. In favorable water temperatures, fry can emerge from the eggs in less than a week.
It is important to feed the fry with small live foods for the first four weeks.
Frozen daphnia is also an ideal diet for black Koi fish. After four weeks, they can be introduced to pellet foods.
When all goes well, you will see their beautiful colors emerge from the fifth week onwards.
The first black Koi fish were known as Karasu in Japanese, meaning ‘crow’.
Later in the 1980s a scale less species of black Koi known as Kumonryu became popular.
The pattern on their body changes with varying water temperatures.
You will find many Koi tattooed on men and women as they symbolize strength and intensity.
This species is usually remains black in winter and changes to
lighter shades in spring and summer.
Matsukawabake is another species of black Koi fish where patterns
on their body fluctuate according to their diet, season, and temperature of the water.
Koi hobbyists enjoy the challenge of breeding and looking after black Koi fish.
Watching them swim in a pond is a breathtaking sight which you ought not to miss.
What does a black koi fish represent? Koi Fish meaning in Japan is good fortune or luck they also are associated with perseverance in adversity and strength of purpose, the Koi fish symbolize good luck, abundance and perseverance. Symbolic in Buddhism is to represent courage.
Are black koi fish good luck? To have a black koi in your pond will be to have a source of good luck, as Japanese tradition would have it. The black koi is considered very good luck.
What does a black koi fish mean? Koi is a Japanese word for Carp. Japanese people have, for years, used Koi fish tattoo designs as a cultural symbol for overcoming adversity. Stories are told of how they climb waterfalls that have strong currents. It is said Koi was determined to reach the top of the waterfall so it persevered and succeeded.
Buy a baby koi! Ya, why not, it’s a wonderful pet to you and your kid, teach your kid how to raise up such a pet, let your kid know about the sea life and how those fish can be raised, breed.
A lot of fun you and your family will have and a lot of information and knowledge you will acquire too and will teach your kids.
Well, a baby koi won’t be that expensive, a sum of several dollars would get you a nice colorful baby koi, though if you tried to begin
with a little older koi so to quick the time remaining for breeding, it would cost you some more money reaching hundreds of dollars sometimes.
But the baby koi, won’t stay that small forever, koi grows to reach 3 feet sometimes, therefore koi isn’t that type of pet you can keep in a tank indoors, as the koi grows it needs a lot of room,
pond in your back yard would then be good enough for it may be, sufficient room has to be considered for each koi you have and this pond
wouldn’t be just a hole in the yard, you wont just dig a hole and fill with water and that’s it, it has special way to design and build and some equipment will be needed too while raising up your new pet.
Good care should be taken of the water those babies are staying in, clean and fresh environment is the one expected if you are seeking in return a healthy, shining, glaring koi growing up in your house, well this goes on when raising up any pet I suppose!
A koi, as other pets, can have its own bought food or you can serve some of your remaining food, like bread, peas, etc.
Your kois would also eat any plant found in the pond! Though they seem always to be hungry but overfeeding really affects their health negatively.
Taking the utmost care while dealing with your Koi is very important to the lifespan that each of them may have.
If you managed raising up your koi for some years, till reaching the right age for breeding, then its time to gain some profit either a money profit by selling some baby koi or more baby koi is added to the fortune of kois belonging to you and your family, you have planted the seed by taking care of your koi all this time and here is you harvest.
Breeding occurs nearly at the age of 4 years, before that age the koi is not sexually mature enough and if much older than this, also won’t give the expected results, reproducing is not that easy at old ages.
Usually breeding occurs between one female koi fish and 2 male koi fishes.
It is better to separate other koi fish that aren’t going to breed for more concentration and focusing between the breeding kois.
So breeding is better to be done in a separate pond or at least a separated part of the pond.
After breeding operation, the pond would be so cloudy and smells unpleasant, this is expected, you should take care of cleaning it and refresh the water.
Koi females are to lay thousands of eggs which have to be separated from adult kois to save them from being eaten.
Baby koi has to be feed around five times daily for the first few months.
I see it an interesting and useful pet, expect your kid’s friends to be asking for a show for the koi or even their parents would like to buy them some of your newly born koi.
After the first generation of kois you will get used to it and you will understand why some hobbyist had that fever of koi’s color patterns and spend a lot of time, effort and money to find what they are dreaming of.
Buy a Baby Koi people ask
How much does a baby koi fish cost? They are certainly colorful, lively and wonderful—but they will not catch the attention of seasoned koi show judges.
Typically, pond-quality koi cost $10 to $100 depending on size
What size koi should I buy? Generally, the ideal size for a Koi pond is considered to be over 1,000 gallons and at least three feet deep.
How much is koi fish in the Philippines? How much does it cost for a koi fish? It is also true that certain varieties of koi are more expensive than others. A high-quality 6-inch (a white fish with large red patches) may cost $3000.
The hobby of keeping Koi is a fascinating one that can
become a lucrative business with a little research and a lot of work. Owning Koi
is a relaxing pastime that you will enjoy throughout your life. The Koi is one
of the most beautiful fish in existence. Their colors are eye-catching and
their agile bodies are quite graceful when gliding through the water of their
pond. A group of Koi can live for more than two hundred years when cared for
properly, although 25-35 years seems to be an average lifespan.
Lived Fish Need Plenty of Room
Since it lives such a long time, the Koi is able to
increase in size dramatically, as long as it has a good diet approved for Koi,
the proper water conditions, and enough living space. It is not difficult to
care for Koi, as they require most of the same care as other fish kept by
hobbyists. The main difference is that Koi require lots of room, so they are
housed in good-sized outdoor ponds.
Koi are intelligent fish, and their antics can be a
source of amusement for many years to come. Koi will swim over to you when you
call them, and like to be stroked and petted. They can be taught to eat out of
your hand, which most Koi owners thoroughly enjoy experiencing. Though they are
naturally bottom feeders, they quickly catch on to eating traditional dry Koi
food that floats on top of the pond water.
Can’t Own Just One
Many Koi owners compare owning these fish to eating a
bag of potato chips, as it is almost impossible to have just one of them! Your
Koi collection can be for your own pleasure, or you can build a Koi business
out of your passion for these fish. A business of this type necessitates a
long-term commitment from you, as you are working with living, breathing
creatures, which deserve the best of care. Many people make pets out of their
Koi, which assures that they get nothing but the best of care. You will get a
kick out of purchasing a feeding ring for your Koi, placing the food inside of
it, then watching as the fish scramble over each other to be first in line.
Your koi will become a big part of your life in many
ways. As a peaceful, relaxing hobby, raising koi cannot be beat. As a business,
breeding and selling koi makes a fine home business for a person who has taken
the time to learn all about koi and how to start a breeding program with them.
Either way, you should be able to sell many of your koi to others for a
rewarding pastime and business.
The Koi has an interesting history. They are the
national fish of the country of Japan, and a member of the carp family
(Cyprinus carpio). This is why some people call the fish Koi Carp. Koi are also
called warrior or samurai fish in Japan. These names have nothing to do with
their disposition. In fact, it is safe to assume that most of the Koi you will
see are lovers instead of fighters! Koi are also known as Nishikigoi, which
means, “brocaded carp” in Japan and other locations. Yet another title for
these interesting fish is “Japanese Carp”, which is rather redundant, as the
word “koi” means “domesticated carp” in Japanese.
Did the Koi Come From?
There is some debate as to where the Koi originated.
Several authorities on these fish believe that these colorful fish first
appeared in the country of Persia, which is now Iran. From Persia, the Koi
gradually moved into and through the rest of the prehistoric world. The fossils
of Koi that are around 20 million years old were found in the southern part of
Koi as a
The first mention of Koi was in a Chinese book written
anywhere from 265 to 316 A.D. The text describing them said that the fish were
black, red, white, and blue. Up until around 800 A.D., the common carp was
raised in Japan as a protein food supplement. Historians are not sure exactly
what was done with Koi from the second century until the seventeenth century,
but they theorize that the fish were so popular with the Japanese natives that
these people gave them to friends, who gave them to friends, and on and on
until the Koi extended across the Orient.
Koi Are Very Versatile
Koi Carp seem to be survivalists, and their capability
to adapt and thrive in so many diverse climates and water environments was responsible
for the fish doing well in so many places. Selective breeding during this time
accomplished several different pattern variations of the Koi. The most common
color during this period was the red and white Kohaku.
In 1914, the variety of Koi known as the Niigata was
taken to Tokyo for inclusion in an exposition, which was held every year. It
was during this time that people all over Japan became enamored of the Koi, and
started to keep them in outdoor ponds at their homes. Soon after this period,
the fascination with koi spread around the world. Today, people are still
captivated with these gorgeous fish.
HOW ARE GOLDFISH
AND KOI DIFFERENT?
Goldfish and Koi may have some similarities, but they
are definitely two different fish. The Goldfish (Carassius auratus) is over a
thousand years old, and was created by the selective breeding of a type of fish
known as the Prussian Carp. The plan was to develop different color mutations,
and this idea was very successful. The changes in the fish were so distinct
that the Prussian Carp and the Goldfish are now thought of as two completely
different species of fish. Goldfish migrated to Japan and Europe during the
sixteenth and seventeenth centuries.
Common Carp and the Koi
The background of the Koi contains a fish known as the
common Carp. In fact, the Koi is a common Carp (Cyprinus carpio) that has been
severely culled over time for color and pattern. Contrary to popular belief,
the Koi is still a common Carp. All that is needed to prove this is allowing a
group of carp to breed with each other at will for several generations. The
natural and original color of these fish will reappear by the second or the
Goldfish are not as large as Koi. Their bodies come in
an array of different shapes, and their fins and tails can be put together in
several diverse configurations. Koi share a universal body shape, but have a
wider variety of body colors and patterns than the common Goldfish. Koi also
have a slender barbell on their lip that resembles a whisker.
Even though Goldfish and Koi may look somewhat
similar, especially when they are young, remember that each comes from a
different genus of the carp. Goldfish and Koi are able to interbreed, and will
produce young fish, but these fish are always sterile.
Varieties of Koi
There are fourteen
different varieties of Koi, with a fifteenth variety that is used as a sort of
a catchall variety for all of the different Koi types that do not quite fit
into one of the other fourteen slots. This last variety is known as the
Kawarimono, and a large percentage of Koi are placed in this category.
Inclusion in this
variety has no bearing on the quality of the Koi. Placement in the fifteenth
variety simply means that there is something not quite right about the fish. It
may be attractive and healthy, but it does not fit the “breed standard” for any
of the individual varieties. All Koi have a unique beauty, but those who are
entered in shows must resemble this standard.
Crossbreeding For Different Varieties
The many different
color varieties that you will see were brought to fruition by crossbreeding
fish that are closely related to each other. Crossbreeding tends to make a
genetic line more stable, bringing out the good qualities while pushing back
the bad. Those who are preparing to be Koi breeders are advised to learn about
the different varieties so that they will know which ones they are interested
in breeding and raising.
The Kohaku is a White
koi with red, or Hi markings. The color white should look as if it is freshly
fallen snow, and there should be no superfluous marks on the white to distract
the eye from the pristine color.
The clarity between
the Hi color and the white is called the Kiwa. The pattern on the Kohaku should
have depth and should be as well balanced as possible. There are several
different pattern types, including the –
Inazuma, which means lightning strike in Japanese.
Nidan is the name for two red or Hi markings on the white
background of the fish.
Sandan is the name for three red or Hi markings on the white fish.
Yondan is the name for four red or Hi markings on the Kohaku.
The Taisho Sanke is a
Koi carp with three different colors. In this instance, the colors are red, or
Hi, black, or Sumi, and white. The color depth and the balance of the pattern
on the fish is important, just as it is on the Kohaku. The Taisho Sanke should
not have any black (sumi) on the head. Black (Sumi) is welcome on the fins, and
most particularly on the pectoral and the caudal fins. This is taken as a sign
that the Sumi color should stay even over the entire body of the fish. The red
(Hi) patterns may be on just a part of the body, or can extend back over the
entire length of the body.
The Showa Sanshoku Koi
has much more black (Sumi) included in its patterns than does the Taisho Sanke.
In fact, this classification is mostly black with a foreground of red and white
markings. Color depth is very important in this variety. The black (Sumi)should
be deep and dark, the color of an object made of the dense and dark black wood
known as ebony.
The red (Hi) markings
need to be a blood red color, and the white should be as crisp and clean in
appearance as a freshly washed and starched white shirt. The white color on the
Showa Sanshoku should be even and uniform on the base of the pectoral fins.
There are several different varieties of the Showa Sanshoku that can pop up in
other Koi classifications, such as the –
Kawarimono (Kage Showa,
Hikari-Utsurimono (Kin Showa)
The Asagi Koi is one
of the initial varieties of Koi. The body of the Asagi is a blue color, with
the lighter shades of blue most preferred. The scales on the skin of the Asagi
are given high importance. The edges of these scales must all be equal in
length, and must be on the entire body of the koi from its tail to its head.
The red (Hi) color that appears on the sides of the Asagi, on the head, and on
the fins sometimes looks more orange than red. The Hi needs to be symmetrical
on both sides of the Koi’s cheeks all the way to its eyes.
Three varieties of the
Utsurimono have been painstakingly developed. These are the –
is a yellow and black Koi
Hi, a red
and black Koi
white and black koi
The Utsurimono should
be heavily marked with black (Sumi) in order to display a prominent contrast
with the yellow, red, or white. All colored need to be somewhat balanced, as
this helps to call attention to the pattern on the Koi.
The Utsurimono is
sometimes mistaken for the Bekko koi. There are two differences to look for
that will allow the observer to tell the two varieties of Koi apart. The main
variation is that the Utsurimono is a black Koi with red, white, or yellow
markings, while the Bekko Koi are either white, yellow, or red Koi that have
black markings. The Utsurimono also feature black markings on their heads that
run all the way down to their noses. The Bekko Koi do not have black markings
in this area.
The word “Hikari”
translates from the Japanese to mean “metallic”. “Mono” means one particular
single color. This means that the Ogon is classified as a highly
metallic-colored variety of Koi. There are –
Metallic silver, or
Metallic yellow, or
These two colors are
the most common, and the easiest shades of Ogon to purchase.
There is also the –
where only the head of the Koi is metallic
Ogon, which is all orange like a common goldfish, with a red splotch on its
back. Goldfish lovers are usually quite fond og the Orenji.
With the exception of
the Fuji, the metallic color of the Ogon must be the same from the head to the
tail, and even flow down to the ends of each fin in order to be considered
“correct”. The size of the fins also matters a great deal. Everyone wants to
see long fins on the Ogon, as they help to counterbalance the plain Koi body.
The Bekko variety is a
white, yellow or red Koi that can be identified by the unique black markings.
This assortment has small and very simple black markings that are not included
on the head of the Koi.
Bekko is white with black markings.
Bekko is red with black markings
Bekko is yellow with black markings, and is considered to be rare.
The Shusui is the result of a crossbreeding that took place in 1910. One
Yoshigoro Akiyama crossed an Asagi Koi with a Doitsu Mirror carp. He ended up
with a fish he called the Shusui. The color of this Koi is comparable to that
of the Asagi.
The Shusui has a head that is a bluish gray color, with red on the jaws
of the Koi. The skin is a lovely sky blue, with darker fish scales outlining
the lateral and dorsal lines. Lines of red run down the back from the gills to
the tail. There are several types of Shusui, including –
The Koromo koi is a
relatively new type of Koi that appeared around 1950. The Koromo came into
existence by crossing the Kohaku with the Naruni Asagi. The Koromo has a lovely
pattern of deep red edged with black on a white background/body. The red is
described as being in a lace pattern, and the markings of the Koromo are prone
to variations, depending on which variety you are looking at. The most commonly
seen varieties include –
In Japan, the word “goshiki” means five colors, which are red, white,
black, dark blue and blue. All of these colors can be mixed on the body of one
fish. The result of this is a Koi that has a rather purplish tint. Originally
created by crossing the Asgai Koi with the Sanke Koi, the Goshiki has patterns
that are quite striking. These surprisingly lovely fish are very popular with
those who keep Koi as a hobby.
Any Koi that are
metallic and have several colors, but do not come from Utsuri lineage are in
this group. The Hikarimoyo-mono was created by crossing a Platinum Ogon with
several other varieties, none of which had any Utsuri genes at all. This cross
resulted in the –
There is another group
in this classification, which has fish of two colors, either gold, orange, or
platinum. These Koi are called Hariwake. The Orenji Hariwake and the Hariwake
Matsuba are two examples of this variety.
classification is given to many non-metallic fish who do not seem to fit in any
other variety of Koi. This classification should in no way be considered as a
variety in which to dump the oddly marked Koi! Many gorgeous crossbred Koi come
from the Kawarimono variety. Often, these are not bred on purpose, but appear
in a spawning as a “sport” koi.
Kawarimono are divided into three groups –
colors of Koi
The Cha-goi is a part
of the catchall class known as Kawarimono. “Cha” is the word for a tea-colored
Koi that is a very fast grower. The Cha-goi is very easy to tame, and most
people thoroughly enjoy having this variety in their pond.
Ochiba-Shigure is an
interesting name for a Koi. The words translate to mean “dead leaves on the
water”. These fish are clothed in the basic colors of gray and green with a
network of brown lines, rather like the stems of a dead leaf.
Also known as American
koi, Butterfly koi, Longfin koi, and Dragon koi, the Onagaoi has beautiful long
fins reminiscent of a butterfly’s wings. The Japanese bred these koi, hoping to
improve the hardiness of all koi by doing so. A type of wild fish called Indonesian
Longfin river carp were captured by these breeders to use in breeding
experiments. These carp were bred with koi that were more traditional in
appearance. The fish that resulted from this breeding had the long fins and the
resiliency that was hoped for.
Koi Purists Dislike the Butterfly
experiments were carried out in the hopes of setting the different patterns of
traditional koi onto the long finned. This attempt at crossbreeding was mostly
successful. Many koi purists are adamantly against the Onagaoi. This is the
reason why many of the people who sell koi do not offer this variety. Famous
breeders in Japan would not think of breeding the Onagaoi. These koi are not
popular anywhere in the world except for the United States.
DESIGNING AND BUILDING A KOI BREEDING POND
If you are planning to breed koi,
then you must start out on the right foot. You cannot simply find someone who
is selling koi, bring a few back home with you, then toss them into a
five-gallon bucket and expect them to thrive in this “new home”. Koi are hardy,
but this treatment would certainly not be good for any fish, much less the Koi.
These fish have the potential to be very time consuming, but you can curtail
this somewhat by doing your homework before even purchasing a few Koi.
A Pond for You
If you want to keep koi, then you
need a pond. It is best to build the biggest pond you can afford, because these
fish can grow in length to reach twenty-four inches or even more. You will also
want to make sure that you have plenty of room for spawning when the time comes
to breed your koi. You may want to design your own pond, and do all the work
needed to build it yourself. You may want to hire someone to design and build a
pond for you. You may decide to purchase a pond liner, filter, and pump from a
dealer who specializes in fish ponds.
Formal or Informal?
One of the best ways to decide
exactly what kind of pond you want is to look at what others have done to
create theirs. Keep in mind that you must decide on how large it will be, and
what shape will fit best in the area of your yard that you have selected for a
pond. Ponds can be formal, or informal, and it is up to you to decide which one
of these styles will work best for you.
Pond Size Counts
Pond size is everything when
keeping koi carp. Large or small, your choice of size is going to affect how
many koi you will be able to keep, what kind of filtration system you will need
to keep the pond water fresh and clear, and how much time, effort, and money it
will cost you to do daily upkeep and routine maintenance on your pond.
Koi experts agree that if you
enjoy koi enough to want to breed them, you need to build the largest outdoor
pond you can afford. You certainly do not want to go to the time and expense of
building a pond (or having it built) only to have to build another one because
your fish are outgrowing the first one!
Pond Depth and Width
Keep in mind that you need to
consider not only how wide and long your pond will be, but also how deep. Long
time breeders insist on ponds that are at least four feet deep, as they claim
the fish grow larger and have better conformation when living at this depth.
Koi also need a pond that is at least twelve feet in length, and has at least
one hundred forty square feet of water surface. Once you see the number of fry
that come from the first spawning in your pond, you will understand why lots of
room is essential! You can certainly have a smaller pond, and enjoy watching
your koi swim and frolic about, but you will not have much luck in breeding
your koi. Pond size is crucial when it comes to breeding.
Where to Build Your Pond
You will want consider carefully
the area on your property that you choose for the location of your breeding
pond. You will want your koi pond to be accessible to you, so that you do not
have to put forth an effort to get to it. If you choose an area that is
difficult to maneuver in during good weather, it may be impossible to navigate
come winter. The same goes for a breeding pond that is built during the fall,
after the leaves are gone. If your pond is too close to shrubs or trees, things
may get a bit crowded in the spring when they leaf out and/or bloom again. You
will also have to put up with leaves dropping into your pond.
It is best to place the breeding
pond as close to your house as possible, so you can see your fish from a window
while inside. This makes it much easier to check on them during bad weather. It
also makes it much easier to feed them if they are just a few steps away from
Sun, Shade, and Tree Roots
You do not want to build a
breeding pond that will be in the sunlight or in the shade all the time. A
little sunshine is good for koi. However, koi can sunburn unless they have a
place to go in order to get out of the sun. Too much shade can inhibit the
growth of the fish. Watch out for the roots of any large trees that may be
nearby. They can snake out much further than you would think. Many an area
chosen for a koi breeding pond has been abandoned because of the massive root
systems of elderly trees.
You can either be sure to choose
an area that is not around any large trees, or choose the type of tree that you
would like around the pond. Many people choose palm trees, as the roots of this
tree cannot hurt a pond. Palm trees are not messy like most trees are as they
shed their leaves. If too many leaves make it into your pond before you have a
chance to use a net to get them out, the resultant decomposition is going to
make your filter work much harder than it needs to.
Providing a breeding pond for
your koi may mean a lot of work for you if you choose to design and build it
yourself. However, you will be rewarded tenfold by taking the time to do the
Aeration and filtration are both
necessary if you want your koi to reach their full potential. You are probably
thinking, “Wait a minute! I’m not sure I want to the amount of breeding that
would require me to have to worry about all of this!” Whether you just plan to
sell off your excess koi in order to help to offset some of the cost of keeping
them, or you have grandiose plans of developing a new variety of Koi right in
your backyard pond, you DO need to worry about aerating and filtering the water
in that pond.
Treat Your Koi as Your Pet
The Koi you will be keeping in that pond should be
considered as much of a pet as your dog or cat. As such, your fish deserve the
best of care. That includes water to swim in that has been filtered to remove
any harmful material and the waste products from the fish. What would happen to
your pond and to your koi if you decided to do without filtration?
Your pond will very quickly
turn a sickly shade of green due to algae build up in the water.
Fish parasites enjoy murky,
algae-filled water, as do other creatures that may well harm your fish. If
just one fish in your pond is infected by a parasite or injured by another
creature in the water, the chances are good that all of your other koi
will experience the same fate.
Standing water that is full
of algae and parasites really smells horrible and looks pretty awful, too.
Do you really think your koi could live in all of that muck? Here is a
hint – They cannot breathe or live in water like this.
Choose a Good Filtration System
You will definitely have to plan what kind of filtration you will use
in your pond. Do not try to save money by purchasing the cheaper filtration
system. You may well regret it if something goes wrong with the filter and
causes you to lose all of your koi. Most experts recommend that you choose a
filter that is able to handle 33% of the total amount of water in the pond.
As an example, a pond that is capable of holding 3000 gallons of water
needs a filter that can circulate 1000 gallons of water. If you must dip lower
than this percentage in order to get a filter you can better afford, you should
not choose a filter that circulates less than 10% of the total water volume.
Your pond filtration system should consist of two types of filtration.
These are –
How Filters Work
Mechanical filtration works by trapping debris and fish waste as they
flow through the water with the use of brushes, pads, sand, or small beads.
Biological filtration involves a natural method that changes the fish waste into
amalgams that will not hurt the fish. All koi have ammonia in the excretions,
and a build up of ammonia can kill any fish. Bacteria that are present in a
biological filter change the ammonia and nitrates in the pond water to
nitrites, which are safe for koi.
Your filtration system will also need a pump. You have two choices of
what type of pump to place in your koi pond. The types of pumps available are –
The submersible pump is a good choice for a smaller pond. If your pond
will feature a waterfall, a submersible pump can be used to handle the volume
of the waterfall alone.
A recirculating pump is usually what is used for good-sized ponds. They
are sturdy and efficient, and most will serve you for a long time.
Your Koi need oxygen
to breathe, just like you. Aeration places oxygen in the water so that the fish
can breathe it in through their gills. If there is no aeration, there will be
no oxygen, and the fish will die. If you are keeping too many koi in a small
pond, or if there is an overgrowth of algae, oxygen levels are rapidly
You have probably seen
koi ponds that feature a beautiful waterfall. Pretty as it is to look at and to
hear, that waterfall is not there for looks only. The constantly moving water
helps to aerate the pond. If a waterfall is not for you, plan to purchase an
air pump. This, along with one of the pond accessories that bubbles, can help
you to get oxygen into your koi pond.
Pond maintenance helps you to
maintain the proper water quality for your koi. It is vitally important for the
sake of your koi that you keep the quality of the water as pristine as
possible. Water quality has to do with much more than keeping the water clear.
You will need to purchase a water testing kit so you can check the pond water
You will also want to make use of

usually done twice a year, in the spring and fall. There are pond maintenance
services that you can hire to do this for you, or you can tackle the job
yourself. It really is not a difficult task. You will need to do the following

the water chemistry, and then take care of any irregularities that pop up.
Removing the Koi
It is understood that you will
remove your fish before this deep cleaning takes place! All sorts of debris and
muck will be floating in the water, and you do not want your fish to struggle
for breath while trying to swim. Koi quarantine tanks are available for
purchase in many places.
What is in the Tap Water?
When first setting up your pond,
you will probably use a garden hose to fill it with water. This is fine, but
you will also need to add a chlorine neutralizer to the water. Chlorine is
deadly to fish, and can kill them very quickly.
Chloramines are also in tap
water, so make sure the neutralizer you use will take care of them as well. Use
your water testing kit each time you add fresh tap water to your pond to make
sure there is no kind of problem with the water. About once a month is often
enough to change out or add new water to the pond. You can bump this up to
every three weeks if the water looks especially needy.
Parasites, Keep Out!
Keep a close watch on your pond
for any type of parasite. You can purchase chemicals to add to the water that
will kill any parasites that may be there, and will also prevent any new
parasites from entering the pond.
To Salt, or Not To Salt?
Many people who keep coy fish insist on adding salt to their ponds. It can be a good idea in quarantine ponds, as it can help those fish that are suffering from stress. However, salt may cause more trouble than it is worth in a pond for breeders or young Koi. When a sufficient quantity of salt is placed in the pond water, the skin of the Koi gets slightly irritated. This causes them to have to produce an extra thick slime coat. That slime coat helps to protect them from parasites and bacteria, which sounds good.
The reality is that salt kept in
a pond all year can cause the parasites that plague your Koi to slowly but
surely build up a resistance to the salt. This will make it harder than ever to
kill off the parasites and rid your fish of them once and for all. A little
salt is fine in the Spring to boost the immune system of your breeders, but
make sure to do your regular water changes in order to clean all the salt out
of your pond when this “spring tonic” is used.
It is exciting to choose and
purchase your first Koi, but do not be too quick in deciding where you will go
for this transaction. If you have done
your homework, then you know about Koi behavior and care. What you now need to
decide is what type of Koi you want to buy. You must also have your pond area
complete and ready to go before buying any fish.
You will probably want to
purchase young Koi for your pond. Older Koi are usually more expensive. As the
Koi does not mature all the way until it is eight years of age, you have the
opportunity to watch it grow. Koi will live to be around forty years old if
they are taken care of properly, so you will be able to enjoy young fish for
some time to come.
Where to Buy Koi
You will want to avoid buying Koi
at the first place you see them for sale. Take your time, and go to all of the
Koi dealers in your area to see what they have to offer to you. Do a visual
inspection of every shop you go in. You want it to be clean and free from any
odors of dead fish or ammonia. Look at the quality of the water in the tanks
where the koi are kept. Do the fish look healthy? Are they swimming happily, or
sitting on the bottom of the tank looking miserable?
Purchasing Koi from the Internet
If you decide to succumb to the
lure of the ads selling Koi that give a web site address, you will want to make
sure that the seller has a stellar reputation. Look for feedback from others
concerning this dealer. You may want to ask those who are more knowledgeable
than you are if they have heard of this dealer. It would be a good idea to
contact the dealer directly and ask a few questions before making a commitment
to purchase koi from them.
Know what to look for when picking out the Koi you
want to add to your pond. You would be crushed if you brought home sick fish to
add to the pond that you worked so hard to build. Ask if the Koi have been
quarantined at the dealers. Most of the time, Koi are kept in quarantine for at
least a month. You will still want to quarantine your new Koi when you get it
home to avoid contaminating the water in the pond should the fish be ill.
Look at the Fish First
It is not difficult to tell if a
fish is not healthy. Koi that are in good physical shape will swim efficiently
around the tank. Check the gills of the fish. They will move regularly and in
unison. If you see otherwise, the fish
may well be in respiratory distress. The koi should not have any sort of physical
deformity. It is easy to feel sorry for the poor koi who is missing fins or has
a crooked spine, but it is best not to but trouble.
Ask the dealer to feed the koi
while you are there, or call beforehand and find out when the regular feeding
times are so you can show up on time to watch. If a koi does not rush for the
food like all the others, chances are good that this particular koi is sick,
and you should not buy from that tank.
How Many Koi Does Your Pond Need?
Koi experts state that you should
have 1000 liters of water for EACH koi you plan to place in your pond.
Remember, Koi can grow to be quite large, so they need this room in order to
reach their full potential. If you are buying Koi for the first time, don’t get
all of the fish you will need at one time. Buy just a few, and make sure your
pond is set up correctly for koi before you shell out the money to completely
Like a human baby, a Koi can grow and reach full
potential only if it is fed properly. Koi are hearty eaters, but the water
temperature can affect their appetite. Water in the pond should be around 15
degrees Celsius to allow the young Koi to feed generously and grow quickly. Koi
have the ability to grow all through their lifespan. Warm weather temperatures
cause Koi to grow faster, and this is why many koi owners who are into breeding
will heat their ponds and feed their fish generally year round. Once a Koi has
reached the age of sexual maturity, a lot of the food eaten is used to get the body
ready for spawning.
the Water Quality
Well fed pond coy fish are known to reproduce and grow on a continuous basis because of all the good, nutritious food they consume. If by chance the water in the pond is not meticulously maintained, their appetite and even their metabolism is affected, which can cause stunted growth.
Commercial Diets and Your Koi
Koi do have certain nutritional
requirements that must be met by feeding them a good commercial diet. If the
Koi in your pond are of all different sizes, remember that the smaller Koi will
need a smaller food to fit their mouths. You will need to feed both small and
large sized commercial foods in order to take care of all the Koi’s needs.
Types of Food
Choose from floating food or
sinking food for your Koi. Most people prefer the floating food, as this
enables them to watch the Koi while they feed. You can also use the floating
food to hand train the Koi. With a little practice, they will recognize you,
and come to the surface to eat from your hand. Feed enough food, but not too
much. A good practice is to feed the Koi only as much as they can consume
within a five-minute period.
There are certain food
supplements that can be used to enhance the colors of your Koi. However, you
should read the ingredients on these, as some additives that are meant to make
the red parts of the Koi redder can also turn the white points of the Koi red
as well! Fish that are in good health generally do not need any sort of color
BREEDING YOUR KOI
Breeding your koi is not a
decision to take lightly. It is definitely not something you can accomplish in
a weekend! You need to realize that breeding koi will be a long-term investment
of both time and money. The prime time to breed koi is from April until July,
so if it is later in the year when you are reading this, all the better. You
will have plenty of time to plan and prepare for koi fish breeding.
Healthy Koi Mean Healthy Offspring
You will need healthy koi for
breeding, of course. Pick your healthiest Koi for this venture, as this will
assure that they are able to spawn offspring that will be of high quality.
Choose koi that are around 25 cm in length. This will ensure that the fish are
sexually mature. Your Koi male needs to be about three years old and no more
than five years old. The female koi should be around four to six years old.
Interestingly, the age of the female Koi has a lot to do with how hard the
shells of her eggs will be. Thin-shelled eggs may not live, while eggs from a
female older than five will have such hard shells that the sperm from the male
is not able to penetrate them.
Time is of the Essence
Once you have picked out the fish
you want to breed, it is best if you do not rush into breeding right away. Take
some time to feed up and condition your fish so as to assure yourself of good
results. Set up a tank or a pond for spawning, and then place one male and two
females in this area when they are ready for best spawning results.
Signs of Spawning
The white, raised spots on the
pectoral fins and on the head can help you spot males who are ready to spawn.
These are called breeding tuberdes, and if you were to touch them, you would
find that they feel rather rough, something like a day old growth of facial
hair. The breeding tuberdes are used by the mail to try to encourage the female
Your Koi Breeding Area
While you are waiting for your
Koi to show signs of spawning, it is a good time to get the breeding pond or
tank ready for them. A place to lay eggs is needed by the fish. This can be as
simple as some evergreen branches tied together, or a piece of plastic pipe
attached to an old, half-unraveled piece of rope. The eggs of the koi are quite
sticky, and they need something available for them to stick to.
The Koi Eggs
You should be able to see the
eggs with the naked eye. Any eggs that are going to be infertile will turn
opaque. Fertile ones will be clear, and you might have to look harder in order
to see them. When it is almost time for the eggs to hatch, you can see a couple
of tiny black spots inside them. These are the eyes of the baby koi.
Remove the Parents
Once you think the Koi have
spawned, you will want to remove the fish from the breeding pond or tank. This
is because the parents will eat the eggs first chance they get if they are
allowed to stay in the tank. Keep the temperature in the breeding area around
23 degrees Celsius for the next few days until the Koi fry hatch out.
Look at Those Eggs!
When the fry have hatched, do not
feed them for three days. Keep the temperature at around 70 to 75 degrees, a
perfect temperature for growing Koi fry. If your female Koi are like most, you
are going to be astonished at the number of eggs you will see. Estimates have
placed the number of eggs a female Koi is capable of releasing at up to
The Babies are Here
Koi fry have marvelous instincts.
They know to hide in any kind of cover they are able to find in the breeding
tank or pond. Many people use spawning ropes for this purpose. The fry are
specially equipped with a sticky pad on their heads. This enables them to
attach to either the walls of the pond or tank, or the fronds that make up the
Baby Koi do not yet have a mouth,
a vent, or a swim bladder. They are able to absorb oxygen that is in the tiny
capillaries that are in the yolk sac of their egg. The fry need plenty of
oxygen during this stage, or you take a risk of losing all of them.
The baby koi have just one
posterior fin when they first hatch out. They grow quickly, and develop their
vital organs, the rest of their fins, and a mouth fast than you can imagine. At
two days old, many of the fry are swimming to the surface in order to fill
their swim bladder with air. At three days, all of the fry should be swimming
around in the tank or pond.
Feeding Koi Fry
Any fry that have developed this
far should be ready to eat. Remember that at this point, their taste buds are
not mature, and the only way they will know that food is available is to see it
floating around them. Most Koi hobbyists use hardboiled egg yolk as the fry’s
first food. Brine shrimp are also a fine
choice of food for baby koi once they have reached about seven days old.
Keeping Things Clean
Feeding the fry is a messy chore
that can really make the water dirty. Keep it as clean as possible using a
siphon, then add fresh water as needed. This will help to take out both the
nitrates and the ammonia from the water. Make sure you have let any tap water
sit for at least twenty-four hours so that the chlorine can evaporate from it.
After around four days or so, you
will want to take out the material that was placed into the tank or pond for
the eggs to stick on. By now, the healthiest eggs have already hatched. Since
you do not have a filter on your fry pond or tank, you want to keep it very
clean. Taking out the leftover eggs will help the ammonia levels.
From the beginning, Koi fry need
water changes several times a day. This can take up a couple of hours of your
time, but is essential if you want your baby Koi to be healthy and vibrant.
By this time, your baby Koi
should be ready to go into what Koi hobbyist called a growing space. This can
be another pond or a good-sized aquarium. You will need to watch the babies
carefully when they are at this age, as it is not unusual for the larger babies
to eat the smaller fry. If you see this happening, you should certainly take
out the larger fry that are munching on their brothers and sisters.
Proper Temperature is Crucial for Growing Fry
The tank or pond that holds the
growing baby koi should be kept at a temperature of about 20 to 25 degrees
Celsius, which is 68 to 77 degrees Fahrenheit. This is to make sure that the
growth rate of the babies stays steady. Just be careful that these babies do
not grow too fast! This can cause the fish to lose their color.
A baby koi that is a week old is
going to need to eat five percent of his or her body weight in order to grow
properly. The trick to this is not to feed too much, but to feed them just a
little several times per day. Once the babies get a little bigger, they will
only need around two percent of their body weight in food.
TURNING YOUR KOI
HOBBY INTO A FLOURISHING BUSINESS
Raising Koi for
If you started your Koi pond with the intentions of selling Koi and
making money, you must understand the koi market. Selling Koi is something like
selling coins from a coin collection. Common coins sell for less than the rare
ones do! Into which one of these markets do you intend to market your koi? If
you choose to sell the rare and special Koi, you are going to need a lot of
experience and a good sized investment in order to be able to compete with the
vendors that are already selling their prized koi.
Hopefully, you are aware that you cannot take just any two Koi, put them
together, and expect to get a batch of champion Koi for your efforts. You may
wind up with 500,000 fry that are the color of mud, and good luck selling them!
You must breed like to like in order to produce Koi that people will want to
buy. It is a good idea to do some investigating, and find out what Koi variety
is the most popular where you live. For example, in the United States, the
metallic Koi are extremely popular. In order to breed what sells in America,
you might want a trio of the Utsuri variety and the Hikarimoyo-mono variety in order to capitalize
on this craving for fish bling!
In dog breeding, if you breed two poodles together, the outcome of that
breeding will be poodles. The same is true with the Koi. For example, you must
breed Kohaku to Kohaku in order to get that variety. There are people who enjoy
crossbreeding the Koi that are of the Kawarimono variety to see what they get, but you should not depend on
this idea to provide yourself with baby Koi to sell. Think of this combination
more as an experiment, to be done after you have become proficient at breeding.
Sources for Quality
In order to make a profit from selling Koi, you are going to need to
locate a source for nice, healthy breeding Koi that are of good quality. Most
of the people who sell Koi in a location other than a storefront are breeders
themselves. Realize that it is going to cost you more to breed your own Koi and
sell them than it would to buy quality Koi in bulk from a trusted vendor, and
then resell them. Expect to pay a nice sum for the sexually mature Koi that
will soon be ready to spawn.
Koi as a Package Deal
Many of the people who are interested in Koi are suppliers of pond
equipment, or are so experienced in either the building of Koi ponds or equipment
supply. These people have chosen to sell their Koi as part of a package deal
that includes a supply of equipment for a Koi pond, or the building of a Koi
pond to go along with the fish. Often, this can get you an exceptionally good
price on a group of young Koi.
Learning to Ship Koi
You will also need to learn the ins and outs of shipping Koi unless you
are certain that you are only going to sell them locally. You may well want to
reconsider that choice as you become more experienced in all things Koi. You
could also take advantage of the packing and shipping expertise that is shared
by members of a Koi club in your area.
In order to become better known in the Koi world, you may want to enter
your Koi into one or more Koi competitions. You would need fish that are as
near to perfect an example of their type as possible. The color of the Koi must
be just right, and size will also makes a difference. When it comes to a Koi
show, color and size are used to classify the fish for the competition. You can
find shows both hear to your home as well as far away by perusing fish
magazines, or doing a search online for Koi competitions. Some shows are free,
while other shows require an entry fee. You may also be asked to join a Koi
organization that is sponsoring a show before you will be allowed to exhibit
A Koi competition can also give you valuable feedback on your Koi.
Comparing your fish to those of others can help you to see any flaws your fish
may have. On the other hand, you may see quality in your fish that you were not
Be careful of buying fish at a Koi competition. They are stressed out,
and many may harbor parasites. You are taking a chance with your money and the
health of your fish at home when you buy a Koi you are unsure of.
Selling Your Koi
You have probably figured out that selling Koi is not quite as simple as
it looks when you see people in a pet store buying fish. You will not be
standing with a smile over a holding tank of fish, netting them out as crowds
of people clamor to buy their favorite! Selling Koi can take a lot of time and
effort. You are going to need a good-sized holding tank for the young fish you
want to sell.
Quarantine for Your
Own Sake – And Your Fish
Moving fish from one setting to another can be stressful. If you
purchased Koi from a dealer and plan to resell them, you will want to place
these fish in quarantine before you sell them to others. Sometimes these fish
will have parasites, which can cause them do develop a bacterial infection.
Both of these maladies are contagious to other fish. Stress can also kill Koi.
Even Koi of your own breeding can be stressed when moved from their familiar
tank to another one. If you are planning on breeding Koi, you are going to need
a lot of room outdoors for quarantine tanks or ponds, nursery tanks or ponds,
breeding tanks or ponds, and hospital tanks or ponds. After you have been in
Koi for a while, you will probably come up with a few more reasons to have
multiple places at your disposal to keep Koi in.
Never Sell a Sick
It would be difficult to maintain a good business if you were to sell
sick fish to your customers. Some vendors do not want to take the time to wait
out a quarantine period of any length. They are in a hurry to get back the money
they spent on the koi they are reselling. This is why it is better to raise and
sell your own Koi. Even though it may take longer for you to get started, you
will be glad you waited.
If you choose to sell fish you have bred yourself, then you will need to
cull the young koi. Any of them who have an off color, poor markings, or some
sort of a deformity should definitely be culled. Do not feel too bad about
doing this! You would not want to take the chance of one of your fish being
accidently bred, and passing on its genetic defect.
When selling Koi that you have bred yourself, it is up to you to maintain an environment for them that is as stress free as possible. Keep an eye on the coy fish you have for sale, and remove any of them that show one or more of the following signs –
Sitting on the bottom of the tank or pond
with its fins tightly clamped
Listlessness, swimming half-heartedly
An ulcer anywhere on the fish
Blood streaks on the fins of a fish
Fins that have started to rot away
Most people start out selling Koi in their own town. You may have
friends and family who own water gardens, and have admired your Koi. While you
will not be able to sell too many Koi in this manner, people will spread the
word about your fish all over town, which may very well bring you some
Selling Your Koi on eBay
You may decide to concentrate on selling your Koi on the Internet. This
gives you the advantage of allowing your potential customers to see photos of
your koi and ask questions about them before they decide to buy them. People
are able to bid on the Koi they like, and the highest bidder gets the Koi.
Selling online may suit you and your schedule much better than having people
come to your home at odd hours looking for Koi to buy.
Other Online Sites
for Selling Koi
Other auction sites online deal in tropical fish and supplies. A little
research would probably unearth an auction for nothing but Koi and Koi
supplies. You can also post online want ads to tell interested people what you
have for sale. If you can, choose a want ad that allows you to show photos of
your fish. In the United States, Craigslist is a good place to sell young Koi.
Each large city has its own Craigslist, and many of the ads can be placed for
Some of the online sites such as Fish.com have their own rules that the
seller must follow. They usually have a “delivered alive” guarantee, which
tends to make people feel more secure about buying online.
Shipping Your Koi
You must make sure that you have come up with a foolproof method of
shipping as well as a couple of alternate plans before you attempt to send a
live fish halfway across the country. The exact method will depend on the –
Size of the Koi
The season of the year
Your climate, and the climate of the
location where you are sending the Koi
How long it will take the package with the
Koi to arrive at its destination
How to Pack Koi for
Most of the time, you will want to pack the Koi in a plastic bag filled about halfway with water. A canister of aquatic oxygen should be on hand so you can place a couple of generous blasts into the bag. This insures that the Koi has enough oxygen to last it until it arrives at its new home. During the winter, there are special heat packs you can use to provide warmth to the fish. There are also ice packs to use during a hot summer.
From the outside, the box you pack the Koi in should look just like any
package. It is not wise to arouse the curiosity of anyone who may come into
contact with the box, for people have been known to tear into packages to see
what is inside if they think it may be an item they would like to have. Seeing
a fish inside a plastic bag, the majority would toss the box in the trash. This
is not what you want to happen to your precious Koi.
The best thing to do when shipping Koi is to use a package delivery
company that can deliver packages overnight. In the United States, you have
your choice of FedEx and United Parcel Service. Both offer Next-Day Delivery,
and are an excellent method for shipping Koi too far away places.
The Koi may be one of the only products that increase in value from one
year to the next. You may decide to raise your young Koi for another year or so
in order to be able to sell them for more money. You can also get a better idea
of a young Koi’s pattern and coloration if you do not rush to sell it as soon
as it becomes old enough. Letting your Koi overwinter in a pond with a mud base
can reveal some lovely fish to sell come spring!
Breeding Koi can be extremely rewarding in spite of all the pitfalls that may pop up along the way. The first time you see a batch of fry from your own breeding trio, you will be amazed at their sheer number. As they grow, you will have a hard time keeping yourself from just camping out beside the Koi pond 24/7. This is just how fascinating baby Koi can be!
coy fish people ask
Why are coy fish so expensive? Good koi are expensive because it is a lot of chance and great selective breeding, they usually spawn one a year and the odds of getting a lot of great animals is very low. They are expensive to keep because of water use, electricity, high quality food and labor
What is a coy fish?
Koi (鯉, English: /ˈkɔɪ/, Japanese: [koꜜi]) or more specifically jinli or nishikigoi (錦鯉, [ɲiɕi̥kiꜜɡoi], literally “brocaded carp”), are colored varieties of Amur carp (Cyprinus rubrofuscus) that are kept for decorative purposes in outdoor koi ponds or water gardens
how deep for koi pond Barebones Requirement for Koi Pond
Whatever you’re reason for wanting to start a Koi pond; you may find the range of options to be quite overwhelming.
It is feasible to spend thousands and thousands of dollars on your
Koi pond before even purchasing any fish!
If you’re just starting, however, you may want to start with
something a little more budget friendly to determine if Koi ponds are right for you.
This guide will cover the absolute essentials of setting up your first
Koi pond for just a few hundred dollars and some honest elbow grease.
In the future, you may become a very successful Koi breeder, but
for now let’s focus on setting up a functional pond that do well enough to keep your fish healthy and happy.
After you get the pond in place, functioning, and stable enough to
support the Koi you purchase—then, and only then, would you
truly be ready to sink into the investment of purchasing the Koi fish themselves.
To begin, you will need the following five items:
1.) A Pond Liner – Simply put, a pond liner will hold the water in your pond. If you dig a hole in the ground and put water in it, it will be absorbed into the soil (unless you’re talking about a LOT of water).
Furthermore, you want to separate you Koi’s environment from
outside contaminants as much as possible. Consider either uPVC
or Butyl; both are readily available from your local home improvement store.
If your hole has lots of sharp rocks in it, you may want to purchase some extra layers or padding to protect the liner.
Since the padding will not come in contact with the Koi, anything
resistant to shredding will work, even an old rug.
2.) A Filter – You cannot have a Koi pond without a filter. Your
filtration needs will depend on the volume of your pond, which
means that if you want to save you should start will a smaller pond.
Unless you are skilled in fabricating your own aquarium filters, you
would be best served by purchasing a filter in the store.
You need a filter to remove debris, bacteria, and toxins from the water.
If you’re working on a budget, take a good look at the filter prices
and their recommended replacement intervals making sure to
factor that cost into your calculations.
3.) A Pond Pump – This will work in conjunction with the filter to clean your pond water.
It is absolutely essential to your Koi’s survival to have a working pump at all times.
If you can afford it, you should always keep a backup pump on hand in case of a failure.
Make sure to check with your aquarium supply dealer regarding pump efficiency.
A general rule of thumb is that your pump should be able to circulate the entire pond’s volume within a couple of hours.
4.) A UV Clarifier – This is a special piece of equipment that fits between the pump and the filter.
It uses UV rays to help the filter remove algae from the pond water. Algae are a special concern in Koi ponds since it is often too small to be caught by most filtration systems.
The UV rays will cause algae particles to bond together so that they
are large enough to be filtered out of the water.
It is feasible to remove algae from the pond by chemical methods,
but this is considered hazardous to the Koi.
5.) A Test Kit – Even experts need test kits. The quality of your Koi’s water must be checked frequently.
One of the most dangerous chemicals to your Koi is ammonia, which can be detected by neither sight nor smell.
You will need two different types of test kits, one for pH, and one
for nitrate (which will indicate filter performance).
Ensuring the quality of your Koi’s water is a major factor in how long they will survive.

Koi are known to live for at least twenty or thirty years when looked after properly.
Moreover, they grow rapidly to over a foot long when kept in a large pond and fed regularly.
Like many other fish, they do not grow fast in smaller water bodies. Although they are coldwater fish, they thrive in temperatures between 60-80 degrees F.
As the carp represents wisdom and longevity, so does the Koi Japanese fish.
Their natural tendency to swim upstream against the flow of water is a symbol of perseverance and resolve.

Koi reproduce through spawning and can produce thousands of offspring in a single spawning.
Not all turn out to be of the best grade. The defective ones are sorted and culled, and sold as lower grade Koi or as feeder fish.
If you plan to add Koi Japanese fish to your pond you need to make sure that the chemical level of the water is suitable.
De-chlorinate your pond and maintain the appropriate PH, ammonia, and nitrite levels.
There are plenty products available in the market to help you measure chemical levels.
Never introduce the fish directly into the water. Keep them in a bag with a slight opening and place it in the pond.
This will allow the fish to adapt to the new water. Carefully release the fish from the bag after an hour.
A good idea is to start with only two or three fish. This will give you time to determine whether they are healthy.
Refrain from feeding them on the first day. Once these Koi adapt to the conditions you can add more to your Koi pond, and wath your school grow.

Koi Fish Breeding Tips The moon is full. It reflects off the water of a fishpond full of koi. It is April and the koi are getting ready to breed.
For some, this is an unexpected event that leads to the sudden
intrusion of many new fish in their formerly spacey pond.
But for other koi owners, this is an exciting and anticipated time of year.
Those who are excited about breeding koi fish, start the preparation
well in advance of the April to July breeding season, and their hard
work pays off in superb koi of exceptionally high quality.
Breeding koi fish can be a challenge, in part because of the sheer size of the fish.
Koi can grow to be large, which can pose a problem when trying to find space for newly-bred fish in a pre-existing pond.
Having plenty of space for all the fish, including both the parents
and their offspring, is crucial to the health of all the fish.
It is also vital to get good, high-quality fish to breed. High-quality offspring can only come from high-quality parents
. If you are looking to buy koi for breeding, you will have to be
knowledgeable on exactly which type of koi you want and what the
signs of a healthy, high-quality fish of that type are.
A good place to start is the coloring and pattern on the fish.
The vividness of the colors and crispness of the distinction between
colors can often indicate the quality of the fish.
Also look at the age of the fish you buy for breeding. Both too young and too old can be detrimental.
A very young female koi may have eggs that are too soft, and therefore more easily prone to damaging.
You could lose many of the offspring produced by a young koi. On the other end of the spectrum is a koi that is too old.
As you may expect, this sometimes leads to the opposite problem. An older female koi could produce eggs with shells that are too
hard, which may prevent sperm from being able to fertilize them. The ideal age is four to five years old if the koi is intended to be used for breeding.
The weather and even the moon can affect breeding. Koi like to
breed during a season when the difference between the high and
low temperature for the day is very slight.
They also like to breed during the full moon. If possible, aim to have your fish breed when the moon is full or nearly full, as this helps encourage the fish to spawn.
One spawning can result in literally thousands of eggs. The male fish will fertilize the eggs after they are out of the female.
The male will also try to help the female release the eggs by pushing her from each side.
Watch the fish carefully during this to ensure the male does not injure the female.
Even if you’ve done everything correctly up to this point and gotten your fish to breed, your work is not quite done yet.
Even after breeding there are steps to be taken to ensure the
continued health of your fish and their offspring.
Separate the fish after the spawning to allow the female to rest.
After this point, it is your responsibility to take care of your new fish and their parents.
With diligence, attention and care, your pond may soon be full of high-quality, individually bred koi guided from egg to maturity by you.

Like most fish, Koi carp lay eggs instead of bearing live offspring. In fact, Koi are known to lay thousands of eggs at a time.
This process may sound easy and promising if you’re considering
breeding Koi for fun or profit, but many factors must be exactly
right for even a small percentage of these eggs to survive so don’t get your hopes up just yet.
This article will explain the process of Koi spawning.
The first component of Koi breeding is a pair of healthy, mature Koi.
The actual art and science of raising healthy Koi is outside the
scope of this article, but there are many resources available.
If you can raise healthy Koi, however, they will reach sexual maturity as early as three years of age.
Sometimes they will not start breeding until they are almost four. It depends more upon their physical growth rate than age.
A pregnant female will be relatively easy to notice among other Koi. They will, of course, appear larger, mostly in the abdomen.
Pregnancy, however, does not equate to fertility in the fish world.
The eggs must be fertilized by a male, and determining when a male is ready to breed is not as easy.
The next most-important factor is an appropriate breeding setup.
Generally it is preferable to conduct Koi spawning in controlled
environment, separate from the other Koi that you may have.
Since the water parameters most appropriate to encourage
breeding are somewhat stressful on the Koi, it is best not to place
the entire flock under this type of strain unnecessarily.
Also, when keeping the spawning pair separate from the rest of the
flock, you can better ascertain the type of Koi you will produce if you are trying to cross-breed.
Furthermore, you will have much more control over the fate of the
eggs, which will improve the overall survivability of your Koi babies.
The ideal setup will have plenty of room for both fish. Expert opinions vary, but temperature should be somewhere around 2-5°C higher.
Always remember to give the female an area to lay the eggs; they will need something to attach to.
Plant matter tends to work best, but even experienced breeders
have been known to use a solution as simple as a mop head to save costs.
Always keep the eggs separate from the rest of the flock. If left open to the adult Koi, they will likely be eaten.
Additionally, it is best if there are some “private” areas within the
breeding enclosure, basically anything that gives the impression of a nest.
Again, some plant matter or even fish netting will work well for this effect.
Koi will naturally breed in the spring. They can sense the time of year through changes in the water temperature.
It would be considered extremely difficult to simulate this, so it is
best to allow this to occur naturally.
If the pair will breed, they will very likely do it in the morning. All of the conditions must be just right.
If they do not breed, try adjusting the water temperature; it may be too cold or too warm.
Make sure they are well fed. You can keep trying, but it is only recommended to keep the Koi in the breeding enclosure for a few days at a time.
They may perish if exposed to the high temperatures for too long.
The eggs, if fertilized, will hatch in seven to ten days after the spawning.
While it was said that Koi will lay thousands of eggs at a time, do
not raise your expectations that each one will survive.
Not all of the eggs are going to make it and you should not expect
thousands of little Koi swimming around for your money making.
Make sure that you set your standards lower and don’t base your budget on the hopes of thousands of Koi offspring in each batch of two mature Koi.
How much do koi breeders make? Prices range from a $15 to $5,000 for the highest quality koi, says CNN Money. Prices are set by body shape and skin quality as well as the color and pattern of each fish. If you grow show-quality koi, you’ll be able to sell them for more money than younger or smaller koi.
How long does it take for Koi to breed? A Koi’s prime mating age is between 3-6 years old, but koi have also been able to produce baby koi fish until they are up to 15 years old. Make sure to give your breeding koi couple some privacy when it’s time for them to mate.
How do koi reproduce? In a pond setting, koi will breed as a flock, or group. … During spawning the male koi will become extremely aggressive. Male fish will pursue the female koi around the pond, smashing into them repeatedly. This battering behavior is designed to force the eggs from the female’s body.
