Fish like any animal requires food to live, grow and prosper. Ensuring your koi receive the best koi food you need to know more about what you are feeding them.

Here is some information that might help you choose the best koi food for your special fish.

If at all possible you should try to stick to feed that is close as possible to what koi fish normally eat in nature.

These fish are voracious eaters.

They will consume almost anything that is available. Therefore it is important that you monitor what they eat to ensure they remain healthy. 

You can choose between feeding live insects or commercially available Koi fish food, or you can give them a combination of both. In addition to their normal food you can supplement their diet with occasional treats such as fresh foods and nutritional supplements.

Koi fish are omnivores.

This means they can and will consume both animal matter and plants.

However, they have a preference for larvae and aquatic insects.

Some people opt not to have plants in their koi ponds because the koi will devour them.

However, you must ensure your koi fish get a balance of plant and koi fish food. The most convenient koi food is a manufactured dried food.

There are different forms such as pellets, granules, chunks, tablets and flakes.

All of these feeds are easy to store and convenient. When considering what type of koi food to use you must take into account the age and size of the fish.

It is also necessary to consider their stage of development and the time of year.

Summer requires a higher concentration of protein because energy levels are higher.

During winter they are less active and need a feed that has less protein.

You will use smaller pellets for smaller fish and larger ones for larger fish.

Some people believe certain foods enhance the colors of their fish.

This works in theory but remember that the red color patterns are genetically embedded.

Red will not be greatly enhanced by extra supplementation. Supplementation can also improve overall health and boost the immune system of koi.

A warning must be given that too much can also prove toxic.

Some fish feed for Koi already contain some supplements so read labels and check ingredients to ensure you are not overdosing your fish.

This will be harmful and even toxic. Apart from commercially manufactured foods you can balance the feed with fresh ingredients like lettuce. Your fish will relish this treat.

Shred leaves and let it float on the water. Romaine and leaf lettuce are the best to use.

Another food koi fish are fond of is oranges. This is high in Vitamin C and a powerful antioxidant. Cut into segments leaving the rind intact. Prawns are a favorite of koi fish.

They are high in protein and excellent for summer months when your Koi fish need additional protein.

Insects and larvae will always be welcomed as food by koi. Meal worms, blood worms, black worms, wax worms, tubifex worms and soft-shelled crickets are usually firm favorites for your Koi fish.

Vigilance and regular checking of your koi fish will monitor their progress, health and well being.

Many people enjoy koi fish in their landscaping ponds.

The fish grow large, are colorful, and thrive well in the outdoor pond environment.

Some pond owners choose to breed the fish to stock their own garden ponds.

Others choose to breed koi fish as a profit making business.

No matter which reason you select to raise koi, it is essential to gain an educated understanding of the fish.

First, koi breeders must learn the appropriate times for breeding.

No matter where you live in the United States, the best months to breed your koi fish are between April and July.

The next step is choosing your fish.

Of course, you will want to stock your breeding pond with both male and female koi.

Males can be identified by the spots on their gill covers and pectoral fins.

Females will have larger abdomens during the breeding season.

When breeding koi fish, it is important to select males and females that are about the same size.

Females need to be at least two years old for breeding purposes.

The ideal age for breeding a female is around four years old.

If the female is too young, the eggs will be thin and there is a less likely chance the baby will survive.

You also do not want the fish to be too old for breeding.

Older fish have eggs that are too hard for the sperm to penetrate.

However, fifteen year old koi have been successfully bred.

Set up your breeding environment so that there is approximately one male fish for every female fish.

Make certain that males do not outnumber the females over 2 to 1.

Some form of either synthetic or natural decoration should be used in the tank or pond.

Outdoor ponds often work well with using water hyacinths.

It may be a good idea to place a net over your outdoor pond to keep insects out and to prevent the fish from jumping onto the sides.

Spawning can be recognized by a cloudiness of the water and a strong odor.

A koi fish may produce over a thousand eggs at a time.

It is important to protect these eggs from adult fish.

Spawning ropes may be used to move the eggs to a safe area and wait for hatching.

The hatching of the eggs typically occurs in a week.

A month or so after the fish have hatched, it is best to begin culling out fish that are not of good and high quality stock.

Continue culling out the fish that are acceptable breeders every week or so until you have a high quality pond of new fish.

These fish will serve as new breeders for future breeding.

It important to keep in mind that only about half of your baby koi will live to reach their adulthood life.

Taking care of your fish will help maintain a high quality for the future generation of koi.

Breeding koi can be a wonderful and exciting business or hobby.

However, it is not a task that should be taken lightly. Raising koi takes work in order to ensure that the highest quality of fish are produced.

Your Koi is a unique species of aquatic life.

The Koi fish symbolizes friendship and love.

It is a popular fish that developed long ago in the 1820s in Japan.

They are sometimes known as Japanese Carp.

There are several colors and varieties available in the Koi.

This fish is often found in an outdoor pool for decorative purposes.

Koi fish can be subject to many different types of koi disease that can be harmful.

It is important to inspect your tank regularly and be alert to the different signs and symptoms of these different diseases.

Treatment for these koi diseases should be started as soon as a problem is recognized.

Cancer

If your Koi has any indication of a circular area around an open wound, it could be cancer.

This type of Koi disease is indicated by a white color with the center being pink.

The treatment for this Koi disease is removal of the cancer tissue.

Infection

An open wound that is discolored on your fish could indicate Koi disease infection.

Removal of the dead skin surrounding the area is recommended to prevent further infection and to promote healing of the area.

You can help your Koi by taking a piece of gauze and rubbing the area.

This has to be done extremely gently.

A soft toothbrush will work well also.

The Eye

A Koi with an eye disease is quite noticeable.

A common Koi disease of the eye is called Popeye or exophthalmia.

It is characterized by a protrusion of the eye from the eye socket.

The cause of this likely stems from either tuberculosis or a mycobacterial infection.

This is encouraged secondary to an eye granuloma, an eye abscess, a choroid infection, a viral infection or trauma.

An eye Koi disease can be difficult to resolve as the Koi’s eyes have a limited vascularity.

The medications used to treat an eye disease in the Koi are not highly receptive to this area.

Tuberculosis in a Koi fish can be transmitted to humans.

Caution when dealing with this problem is highly recommended.

The Mouth

An ulcer or an abscess may be found in some Koi fish.

Your Koi will have difficulty closing its mouths if he comes down with this affliction.

This ulcer or abscess will most likely have come from a bacterial infection.

The infection travels through the mouth region and inflames the ligaments of the Koi fish’s mouth.

Starting your Koi fish on an antibiotic as soon as possible is ideal.

However, permanent damage to your Koi may already have taken place.

Enjoy your Koi fish and act upon the first sign of any illness to avoid further koi disease of your favourite pet.

Always consult your local vet or koi expert if you are in doubt at all. It could be disastrous to leave any koi disease untreated.

Koi are some of the most attractive and entertaining fish you can have in a pond.

However, there’s more to keeping them than just dumping a few into the water.

You’re going to need to have a basic understanding of outdoor ponds and how to keep koi, as well as the right koi supplies.

Let’s take a look at some of the items you might want to buy to keep your koi pond running properly.

Not all of them are required, but they’ll improve your water feature:

1. Fountains
   A fountain can be a tranquil, pleasant addition to a pond, as well as a way to drown out noise from the pond pump. It also keeps the water aerated, so that your fish will breathe easier. This is probably the easiest way to keep your pond properly oxygenated.
    
2. Filters
   A filter is a must in the vast majority of backyard ponds. After all, natural ponds filter themselves, but yours isn’t attached to the network of streams that a natural pond has. This means that you’ll need to install a filter to maintain water quality and remove waste and other pollutants. An unfiltered pond will eventually sicken and die, and so will your koi.
    
3. Pumps
   To operate a filter or a fountain, you’ll need a pump. The filter can only work if the water is moving, after all. The strength of your pump can have a lot to do with the health of your pond – too strong and it’ll kill the fish, too weak and it won’t filter the water properly. Fountains and unpowered waterfalls aren’t strong enough to filter the pond on their own.
    
4. Dechlorinator
   If you refill your pond with municipal water, you may need dechlorination chemicals. They’ll remove the chlorine from your city water and allow the fish to survive in it.
    
5. Water Quality Test Kits
   Check the nitrate and pH levels of your water on a weekly basis. This can be done using appropriate test kits. They’re easy to use and will help you maintain a healthy pond.
    
6. Water Chemicals
   To regulate the nitrate levels and acidity of the water, keep baking soda or pond salt on hand. This should be used in appropriate levels when the tests show something is off balance.
    
7. Pond Netting
   Koi are brightly colored fish that tempt all kinds of animals. This means that you need to protect them from herons, cats, kingfishers and all kinds of other animals. Place your net over the whole pond to keep the koi safe, or use shade and pond design elements to give them safe places to hide.
    
8. Food
   Keep snacks, treats, and a commercially formulated food specially for koi on hand. These friendly fish will be happy to eat right out of your hand, once they get used to you.

Koi come in a wide variety of colors and patterns.

The black koi is one of the original varieties descended from the Chinese carp.

Even black koi come in a variety of patterns.

When you venture into the world of koi, it is wise to learn as much as possible about the varieties you are interested in.

The Magoi is the original black koi and is still closely related to the carp.

Its entire body appears black, but when viewed up close the scales are actually a dark bronze in color.

The Magoi is a very large fish, often reaching 3 feet or more. It is being bred with many other types to increase the growth rate of some other koi varieties.

The Karasu, or Crow, is a black koi that appears solid black when viewed from above.

Its belly however is usually orange or white.

The Hajiro is black with white nose and fin markings.

One of the most popular types of black koi is the Kumonryu, or Dragon Fish.

It is a black fish with white spots that is said to resemble a dragon flying through the clouds.

Like other varieties of koi, black koi can change color.

Some are affected by what they eat, the temperature or their health.

Seasons cause some koi to change their look.

The Matsukawabake koi is known for this ability.

This black koi will change from black to white and back to black again depending on the circumstances.

The ability to change color is one of the unique characteristics that make koi a popular pond fish.

If you find black koi interesting, you may be tempted to have some of your own.

Be sure you put them in a large pond that will provide adequate space for their large size.

Koi will breed once they reach a length of about ten inches.

A female koi can lay up to 1,000 eggs after breeding.

After spawning, the eggs will hatch in four to seven days, depending on the water temperature.

Baby koi, or fry, will not show their coloration patterns until they are between three to twelve weeks of age.

Through centuries of breeding, all the varieties of koi known today, have been developed.

When planning for your koi pond, take into consideration how your chosen location will fare during each season.

Is there shade in the summer?

Will it freeze during winter?

While your koi will slow their metabolism during cold months, the pond needs to be deep enough to give them a safe place to spend the winter.

You may notice that as the water gets colder, some varieties of black koi will begin to change color.

Koi of all types can live a long time.

While most, including the black varieties will live from 25 to 35 years, some can live an exceptionally long time.

Records show that many koi live up to a hundred or more years.

The record holder was a 226 year old red koi who died in 1977. They estimated her age by inspecting her scales.

So, what is the difference between Koi and goldfish?

Koi and goldfish are very similar looking fish, especially when they are about the same size. It is no wonder that some people mistake them.

They are even related – both of these types of fish are descended from carp.

However, koi are a much more recent development, descended from the common carp in Japan.

They were first bred for their beautiful colors around the 1820s, and have been popular ever since.

Goldfish, on the other hand, have been around for much longer.

Domesticated carp were raised in China for thousands of years for food.

These were the Prussian carp, rather than the common carp, which koi are descended from.

Colors like red, orange and yellow were noted as early as the Jin dynasty – around the time of the Roman Empire.

Later, it became popular to raise carp in ornamental ponds, and many of these carp showed gold coloration.

They were prized as ornamental fish, and were displayed in small bowls on special occasions.

Now, goldfish are available in all kinds of colors and shapes, and are actually considered a separate species from their ancestors.

These fish can no longer successfully interbreed.

Koi, by comparison, are still capable of breeding with their parent species, and will return to the wild coloration within a few generations.

They are merely a special series of color variations on this type of fish.

Most goldfish can not be kept outdoors anymore, and must live in indoor aquariums.

Some special varieties, including the shubunkin, are capable of living outside.

Koi are capable of living outdoors in appropriate environments, and are still kept in ornamental pools.

They are also larger than goldfish, though their smaller cousins get bigger than most people know.

If you have only ever seen goldfish two to six inches long, you may be surprised to learn that they can live up to twenty years and get up to eighteen inches long.

Koi can be up to three feet long and usually live for twenty-five to thirty-five years.

Specimens up to six feet long and two hundred years old have been claimed.

Goldfish come in a wider range of variation than koi, with more types of tail and fin shapes and different body shapes.

Koi are almost all the same shape, but have a wide variety of colors and patterns, with obvious barbels on their lips.

Young koi and young goldfish of certain types can be hard to tell apart, and some kinds of goldfish can even interbreed with koi, but the result is sterile.

Both koi fish and goldfish are fun to keep and have their own special characteristics and personalities.

Are you someone who loves the idea of beautiful living jewels in your garden?

If so, it is time for you to look into keeping a Koi garden!

A Koi garden is a garden that makes good use of a Koi pond as a feature.

This Koi pond will hold the gorgeous decorative carp known as the Koi, which has been bred for its beauty and its grace for more than two hundred years.

A clear pond that has these orange, white, black or gold fish in them can make any garden a place of peace and tranquility.

If you want to make your Koi pond stand out, you will find that there are a few things that you need to know.

When you are looking at adding a Koi garden to your property, you will find that you are essentially creating a small eco system.

You are going to be creating an aquatic environment that is going to nurture your Koi, and that means that you need to look into the structure of the pond itself.

Remember that you need to make sure that you are dealing with a pond that is at least four feet deep.

A deeper pond will allow the Koi to stay warm when the weather turns, and you will also find that it will keep your Koi safe from cats, raccoons and other local predators.

Your Koi can grow upwards of three to four feet long and they will need plenty of space.

If you are looking for a good place to put your Koi garden, remember that it is important to keep it out of the direct sunlight.

A Koi pond with too much direct sun is not the best environment for the health of your fish. And it makes your Koi vulnerable to predators that may fly over.

A Koi pond underneath a tree helps to keep the Koi safe, but you will need to take care of debris that falls into the water.

You should never use pesticides or other harmful chemicals near your Koi, as the fish themselves can be quite delicate.

Koi can sometimes be quite troublesome when it comes to plants in the pond.

No matter how well you keep your Koi, they will dig up the plants that are in your pond.

Some solutions include placing gravel and large stones on the plant roots to keep them grounded, but you might also want to plant lilies.

Lilies are usually ignored by Koi and they will help your Koi get the shade and shelter that they need.

There are lily varieties that do well in deep water and others that do well in shallow water.

Take some time and consider all the beauty and pleasure that you can get from a Koi garden. It is a great experience to build and even better when it is built and you are feeding your Koi from your hand!
