After a few months of the trial using Hi-Silk 21 Koi food, we have seen the significant changes of our fishes. Therefore, we will explain our review about this Japanese made koi food which has been established for more than 25 years. During the trial period, we mixed the Hi-Silk 21 with Saki Hikari Wheat Germ and Saki Hikari Color Enhancer. Improvements can also be seen from the quality of the skin after the second week of this treatment. These are the lists of the outstanding improvements that we found :

  • the size and shape of the body
  • color developments
  • the skin is cleaner and shiny
  • sumi and beni get thicker
  • body scale looks better

Hi-Silk 21

From the point that we stated above, Hi-Silk helps the development of the body growth (size and shape). Hi-Silk was developed by Mr. Kawaguchi of Kawaguchi Shoten Co., Ltd and Mr. Mamoru Kodama, author of Kokugyo books and founder of Kodama Koi Farm about more than 25 years ago. The Innovation they created was by adding silkworm pupae to the koi pood. The silkworm itself was provided by Mr. Kawaguchi.

Silkworms contain a prominent amount of protein that dissolves into amino acid when consumed by koi fish. The amino acid will be distributed back to the body as protein. The amino acid structure of silkworm pupae is very close to that of Koi. So, the conversion rate of the food into nutrients is very high. Other than silkworm pupae, silk powder in the food will enhance the Koi’s skin’s white ground to become whiter which is similar to Wheat Germ. This is the reason silkworm pupae are known as the best growth food for Koi. This is the picture of the body improvement of one fish from our pond :

As you can see from the picture, the body of this Showa becomes wider and bulkier after a few months of using Hi-Silk 21 and the skin quality of the fish improves as much as the body. Our rate for Hi-Silk 21 is 9.5 out of 10

Saki Hikari (Wheat Germ & Color Enhancer)

Saki Hikari is one of the famous Koi Food Brand that is used by many Koi Farmers around the world. During our experiment, the products that we used from Saki Hikari are Wheat Germ and Color Enhancer.  Saki Hikari Wheat Germ is made using Garlic and Brewer’s Yeast that supports the immune system and helps to whiten the skin. Another benefit of Hikari Saki Wheat Germ is that the food can easily digested by Koi so it keeps the digestive system healthy. Improvement of our fish that we see from using Hikari Saki Wheat Germ is that the skin gets whiter and when combined with Color Enhancer makes your Koi looks a lot better. Saki Hikari Color Enhancer works perfectly in the development of our fishes skin color. The increment brightness of the skin color can be seen after just a few weeks of treatment. Moreover, it gives a beautiful shine to our Koi Fish. These Koi Food are worth trying! Our rate for Saki Hikari Wheat Germ is 9.0 out of 10 and for Saki Hikari Color Enhancer is 8.5 out of 10.

We will make another review about the other koi food later, so stay updated to our blog posts. Comment below if you have any suggestion about the koi food brand that you want us to review.

 

 

 

Koi is a graceful pet and doesn’t hard to care. Koi types and colors diversity bring their own beauty to the audience, this is what makes koi a very popular pond fish. Because, it is an animal that lives in water, the symptoms of the disease and how to deal with the disease are slightly different from animals in general. Proper care, tank care and your ability to diagnose symptoms will help keep your koi healthy and allow you to overcome problems that may arise. In this article, we will explain the causes of koi disease, characteristics if your koi has a disease, and how to prevent it as well.

Causes of Koi Disease

Koi are very hardy, resilient fish. In most cases, stress is the cause of most diseases in fish. The stress that causes fish to get sick is usually in the form of poor water quality, overcrowding or other environmental factors. If koi kept in ideal conditions, they rarely get sick because they are able to fight off possible attacks from parasites or bacteria.  So here are some of the causes such as; Stress, Poor water quality, Introducing sick fish to the pond, Overcrowding, Contamination, etc

Looking for Signs of an Unhealthy Koi Fish:

There are several ‘early warning signs’ that indicate that your fish may be under attack from parasites or bacteria. The first sign of a problem usually starts with one fish that segregates itself from the rest of the company, often hanging drowsy near the surface of the water. If this fish doesn’t eat, it’s a sure sign that something isn’t right. Recognizing the first signs of disease is important, because it can be controlled much more easily if it is discovered early. Depending on the situation, a disease can spread to many or all fish in the pond relatively quickly. It’s always a good idea to take count of your fish at feeding time and also take a close look at them while they are close to the surface. So here are some of the sign of an unhealthy koi fish such as; Not eating, fish segregating itself from others, fins clamped close to body, fish acting drowsy, gasping at surface of pond, fish always stay on bottom, hanging near surface or near waterfall, red streaks in fins, white spots or black spots, ragged fins, fish acting uneasy.

How to prevent disease:

If one of your koi shows any of the Signs of an Unhealthy Koi Fish, then find the recommended medication and begin treatment as soon as possible. If you have just one fish that is sick, you may want to set up a quarantine tub or treat only that fish. On the other hand, if you have much fish that are sick, treating the whole pond is advisable for best results.

Most importantly keep good pond environment, by maintaining optimal water quality because by maintaining optimal water quality your fish will be healthy, their immune systems will be strong and the fish will be more able to fight off any potential disease threats.

  • Maintain optimal water quality in your pond, poor water quality is probably the main cause of disease outbreaks. You can have a good water quality by not overcrowding your fish, installing an excellent filtration system and performing proper pond maintenance.
  • Quarantine all new arrivals. New fish, no matter how well they have been quarantined at the koi dealer may bring parasites into your pond and bacterial clash.
  • Doing regular filter maintenance, and water quality testing.

That’s all we can share about how to find out if your koi are unhealthy, but if you have something to ask or add to the article please dont hesitate to comment below. we would like to hear and discuss about it.

 

 

 

People often ask us about how to handle new bought koi into their environment, especially those who haven’t experienced in fish quarantine. You can use this guide to properly introduce new koi fish into your pond using the proper quarantining, pond care, and water quality control methods for good husbandry in koi care. Based on our Japanese breeders and koi farm, these techniques are what work best when receiving Ben’s Koi Farm’s Koi fish but are also good tips for any koi pond owner adding more koi to their pond.

Adding new koi to your pond is exciting and fun but should be approached with caution. If you have not added any outside koi in over a year then take extra precautions mentioned in this article below. The natural instinct for Nishikigoi is to coexist with others and to bring peace into a home, which is part of their attraction along with their beauty.

Before You Receive Nishikigoi

A necessary tool for all koi hobbyists and owners that should be prepared before the fish come to your place is a separate quarantine tank. Basic supplies needed for a quarantine tank consists of 100-300 gallons tank or blue show vat, net cover for the tank, small pump and filter, air pump, pond heater, salt, and thermometer.

It is strongly recommended that every koi purchased should be quarantined before adding to your aquarium or pond. That is because it is possible that newly purchased Nishikigoi carry parasites, bacteria, fungus, and other illnesses despite all the best efforts done to eliminate them. Koi fish tend to become extremely stressed and exhausted while in transport from the farm or breeder to the owner. That’s why we cannot just put the fish directly into our pond and need to quarantine and observe the condition of the fish as well.

Prepare the quarantine tank depending on the size of your koi. We recommend 100-300 gallons, blue show tanks are OK too. Maintain a water temperature of 24° C or above. If working with a smaller tank, 1-2 aquarium heaters will work to achieve that.  Ideally, the quarantine tank should have a filtration system as well, but sound aeration from an air pump is acceptable. Add salt to the tank until it is 0.3% concentration (3 pounds of salt per 100 gallons of water)

When You Receive Nishikigoi

Pet supplier usually send the fish using cargo or train packed with styrofoam box or send it by themselves if the supplier is near your place. When you bought fish from 2 or more different fish supplier, pay extra attention when you put them together in the quarantine tank. the steps to do are float the plastic bag for 20-30 minutes before releasing fish to the tank to make the water temperature of the plastic bag equal with the environment. After that, you can put some water from your own tank to each plastic bag and wait few moments again to prevent stress to the fish. the next step when the water from your tank mixed with the water from the fish supplier is, lift the fish and move the fish to the quarantine tank without pouring the water from the plastic bag in order to avoid the bacteria clash from different water sources.

What To Do After You Receive Nishikigoi

It is recommended to keep and treat newly purchased koi fish in a separate quarantine tank for at least 21 days before introducing them to your pond or aquarium to reduce the risk of disease while giving them time to adjust with the new environment. Observe them and see if they develop any problems. If you working without a filtration system, do partial water changes every 2-3 days of about 25% level of water and then add salt to adjust accordingly. Feed your Nishikigoi with digestible koi food and check nitrate & ammonia level every day.

Please note – If you have not added any new koi in over a year, it is particularly important to quarantine both new and existing Nishikigoi. It is highly recommended to introduce one of your old Nishikigoi into the quarantine tank after the new koi has gone through the normal procedure to ensure that all koi in your pond can coexist in the same water conditions and ecosystem. We also suggest raising the salt level to 0.5% in this scenario.

 

That is all about how to handle new koi after receiving from the breeder or pet supplier. Hope you guys can understand and apply this method easily.

So, you have decided to become a koi parent – congratulations! You definitely won’t regret investing in the peace that koi fish can bring to your life, but, first thing first they need a place to live. Your koi pond is going to be a permanent fixture in your yard, therefore you need to come up with some koi pond ideas before you start working. The best way to decide on what you want your pond to look like is to look at some koi pond ideas or examples either in person or online. in order to help, we have come up with some great koi pond ideas that will be your consideration in building the perfect koi pond!

NATURAL

What is more relaxing than sitting by a koi pond surrounded by trees and flowers? Creating a pond that looks like it was always a mainstream koi pond idea for good reason. A natural setting creates a peaceful atmosphere perfect for relaxing and admiring your koi. It is also fairly easy to create a natural looking pond and still change it so it is unique to your yard. A natural pond always has a random shape, but it looks like a bean shape in common and is ringed with rocks and different types of greenery. Adding a small waterfall or another water feature will add even more charm to your pond!

MODERN

If you like the look of things that are simple, neat, minimalist, and symmetrical, this koi pond style will be perfect for you. Ponds with a more modern style are satisfyingly symmetrical and neat usually ringed in cement with little foliage around the pond to distract from the beautiful fish in the water. There is no better style of a pond if you want to attract attention to an award-winning koi! You can add a fountain to the pond to add to your ponds beauty or even an elegant waterfall. However,  it is important to remember with this type of pond that your koi will need a decent amount of shade so be sure to place the pond in a shady area.

CREATIVE

Your pond is going to be a focal point of your backyard so getting creative with it can add a lot of personality or functionality to your yard. Moreover, you can even make an indoor pond if you don’t like an outdoor pond as well. If you can put enough water in something for a koi fish to live happily you can probably turn it into a pond for your koi so go crazy! A few koi pond ideas that are fun and creative are to turn a classic brass tub into an odd but charming koi pond, or you could turn a few large vases into a series of small ponds. If you have found yourself with a rarely used swimming pool you can even turn that into a large koi pond, so get creative and work with what you have!

 

Hopefully, with these koi pond ideas, you have an idea of what you would like your pond to look like! Remember to plan everything out to be just right before you start digging and create the perfect pond for you. Once you finish your pond set up, it is going to be hard to rework or make a change to the pond. Make sure the design of the water circulation and filtration system is going to work properly so the water can be clear enough from the surface and the fish are living healthy. And make sure there are no sharp edges and harmful material that will potentially damage the fish skin.

What does your pond look like? How long did it take you to build your koi fish pond? Did you run into any problems along the way? We would love to hear from you so comment down below!

With the many varieties of koi now available, it can be difficult to understand how each one came to be. We have provided a useful lineage chart below that can help you to better understand how your favourite koi fish developed its unique colour and pattern. It is important to note that given that there are now hundreds of different koi varieties, not all are listed.

Here is some example of selective breeding which has done by breeders in the world.

Asagi: One of the oldest breeds of koi; started being bred 160 years ago by parent Asagi Magois.

Ki Bekko: Bred around the mid-late 1800s by a Magoi and Higoi variety.

Kohaku: Bred by a white female with a red head and a white male with a cherry-blossom pattern.

Sanke: Established around 1917 after breeding a Kohaku and a Shiro Bekko.

Shusui: Bred around 1910 by an Asagi and a Doitsu mirror carp.

Ki Utsuri: Started to be bred around 1921 by a Ki Bekko and an Asagi Magoi.

Shiro Utsuri: First-bred around 1925 between a Magoi and another variety that is unknown.

Showa: In 1926, the Showa was bred by a Hi Utsuri and a Kohaku.

Yamabuki Ogon: Was first-bred in 1957 between a light-coloured Ogon and a Ki-goi.

Doitsu Kujaku: Were first bred in the 1960’s between a Hariwake and a Shusui.

Beni Kumonryu: A rare form of Kumonryu, this variety was first bred in 1980 between a Kumonryu and a Doitsu Kohaku.

Kikokuryu: One of the newer varieties of koi carp, they were originally bred in the early 1990’s between a Kumonryu and a Kikusui.

The best part about raising koi fish is feeding them! Seeing them come to the surface and even eating from the palm of your hand is the best bonding experience between growing koi fish and their owners.

It’s said that koi have a memory of around three minutes, yet they can learn to recognize their feeders. We’ve assembled some great tips to help you become a become your koi’s favorite feeder.

While smaller fish prefer flake food, pellet food shown here is good for larger fish.

KOI FISH FEEDING TIPS:

  1. Feed your fish up to four times per day. Only feed them as much as they can eat in about a five minute period and do not overfeed. try to net it out if there are any leftovers in the pond.
  2. Koi are cold-blooded animals that should not be fed when the temperature falls below 13° C. Their need for food is greatly reduced and correspondingly, so is the rate of digestion. At the ideal temperature of 21-23°C, Koi can consume approximately 2-3% of their body weight in food/day;
  3. Koi fish eat just about anything, from small bugs and insects, to plants and algae at the bottom of the fish pond, to store-bought koi fish food.
  4. Koi will even eat people food. They love cereal, lettuce, shrimp, rice, peas, watermelon, pretty much anything we like, koi fish consider food.
  5. Avoid feeding your koi fish before rains. Fish need more oxygen when digesting food. When it rains, oxygen levels in the air dip down, so you can see why it’s a bad koi fish feeding time.
  6. Your growing koi will remember you as their feeder after only a short amount of time. Consistently feed them and they will begin to greet you as you approach the pond.
  7. Your smaller koi fish will need to eat flake or small sized koi food. Larger koi fish prefer pebble food
  8. Koi fish can go all winter without eating for example in the country like Japan, because their metabolism slows.
  9. Koi fish feeding is not recommended if your pump or pond aeration breaks because your koi need oxygen to digest their food.

Hi Koi Enthusiasts,

Many of us have already been collecting and picking koi fish for our ponds. But, many of Koi enthusiasts probably don’t know how to choose good Koi for their pond or maybe this is the first time for them to pick up koi because they just have set up a new pond. There are meanings behind those beautiful koi colors and different color shows different meaning. There are people interpretation of Koi and some things that Koi can symbolize as well. Today, Ben’s Koi Farm will share some knowledge about koi colors meaning and how to choose young koi to give you some consideration for adjusting Koi Fish pond proportion and to make sure that you choose great potential young koi to grow and develop correctly in the long term.

As mentioned earlier,  Different meanings are associated with each color. Some of the major colors of koi fish are:

  • Black
  • White
  • Red
  • Yellow, orange, or gold
  • Bluish gray
  • Cream

Black

The black koi is associated with successfully overcoming an obstacle. This symbol is great for those who have gone through a tough battle in life and have finally made it to a place of strength. In Japanese culture, mothers, fathers, sons, and daughters are all symbolized by different-colored koi fish. The black koi is the symbol of the father.

Red

The red koi often has the connotation of love. Not just any love—a very intense love. A red or orange koi is a symbol for the mother of the family, and a red or pink koi is a symbol of a daughter. Red koi can also symbolize power and bravery, both common associations with the color red.

Blue

The blue koi is often very masculine and can be associated with reproduction. Blue and white koi are symbols of the son of a family. As with anything blue, it also represents peace, tranquility, and calmness.

Yellow

Koi often have a combination of orange and yellow. These gold-colored fish symbolize fortune and wealth.

As a Koi lover, we might be having a favorite variety of Koi, but the color balance in the pond is also important which mean it’s better to mix some of the other variety of Koi to make the pond proportion looks good.

When hobbyists are looking to buy small koi, They will select koi that appear to be more finished. the word “finished” that we mean is determined by a deep red color, solid black and bright white base. While the finished koi does have immediate appeal, often the finished look of young koi does not last.  As the koi gets older, the color can break apart and fade. Later on, you will end up with a koi that is not nearly as nice looking as when you bought it.  We can avoid this by purchasing young koi that are not yet finished and we try to predict the future of the Koi development.  It doesn’t easy tell the future of a koi and you need to develop an eye for what the colors will do.  Developing this eye and gain experience usually takes years, in order to completely understand what will frequently happen during Koi development.  We need to watch lots of koi grow and develop.  Selecting tosai with a lot of potentials is a skill that breeders can often take a lifetime to perfect.  But there are a few basic things to look for that can help you pick koi with more potential.

First look at the Hi (red).  On young koi, this is often a lighter more orange color and it will turn a darker red as it gets older.  The lighter orange is often referred to as “soft”.  Young koi with a dark red Hi are usually male and have a higher chance of losing their Hi in a couple years.

Next look at the Sumi (black).  Sumi is much harder to predict.  It can come in, fade away, and then come back years later.  Sometimes it takes years to come in, sometimes it never comes in.  Usually, if you have hard water (a high pH) then Sumi will develop faster.  On young koi, underlying sumi has a light bluish color.  This is developing black that has the potential to come in later.  A young koi with lots of dark inky black is again probably male and stands a better chance of losing the color sooner rather than later.

Lastly, we look at the white.  On a younger fish, the white can be a bit pinkish.  This is perfectly acceptable as the color plates are not fully developed.  The young koi can have very blurred sashi (leading scale edge of the Hi).  This is caused by the thin white scale covering the red scale under it.  As the koi ages and the white thickens the sashi should tighten up.

These are just a few basic traits to look for when shopping for young koi.  Of course, there are truly no guarantees when purchasing young fish, but even when they don’t turn out as expected you learn a lot by watching them develop.   And over the years, as your eye develops, your selections will improve.

 

 

 

Owning Koi Fish can be a huge commitment, not because they are high maintenance, but because of how long the Koi lifespan is. The average Koi breed outside of Japan can be expected to reach fifteen years of age, but the average Japanese Koi’s lifespan is forty years. So why are these averages so far apart? There are several reasons for this huge difference in life expectancy.

GENES

Japan is the origin of the Koi Fish and as such the breeders there have had a chance to greatly enhance the gene pool. Even when Koi were first introduced to countries outside of Japan, the highest quality Koi did not leave Japan, this means that Japanese Koi are dramatically better than “Domestic Koi”. In order to catch up with the quality of Japanese Koi, western breeders force Koi to grow faster and this has led to a reduction of their lifespans over time.

FOOD

In their eagerness to breed Koi which can equalize Japanese Koi, western breeders also often feed their Koi an over-rich diet which leads to obesity and early death. Japanese breeders on the other hand often move their fish to large earth dams over the summer which allows them to forge and gain more weight and strength in a very natural way. This is not something the average Koi breeder can replicate but by avoiding overfeeding obesity can be avoided and your Koi’s lifetime can be increased.

WINTERING

Japanese winters are bitingly cold and as a result Koi raised there spend more time wintering than Koi in most western countries, and breeders rarely keep ponds warm enough to keep Koi from going into their winter hibernation. In the west, the desire for large Koi often drives breeders to skip this hibernation period as Koi do not gain much weight during it by warming their ponds to simulate summer temperatures. This hibernation greatly increases the Koi’s lifespan, in fact being raised in a cold environment is one of the reasons Hanako (The worlds oldest Koi Fish) lived to a shocking 226 years of age.

 

The difference between a Japanese Koi’s lifespan and that of a “Domestic” Koi varies according to the type of Koi fish as well. Newer types of Koi, such as the Utsurimono, are more similar while the most ancient varieties, such as the Kohaku, are very different depending on where they come from. As with other pedigree pets, such as cats and dogs, different varieties of koi will have different life spans. Knowing the type of koi that you keep in your pond will help you to make a more accurate prediction of their potential longevity. Nevertheless, the Koi lifespan really relies on how well the owner cares for it, if you feed your Koi a properly balanced diet and ensure your pond is well cared, your fish will have a long and happy life no matter where it is from.

Were you surprised by how different Japanese Koi and “Domestic” Koi are?  Another factor which I didn’t mention about that probably affects the low lifespan of Koi  is our inexperience with raising Koi. We have lost a lot of our ornamental carp because of mistakes we made getting started as Koi owners.  We need continuously learn from our mistakes and experiences, from other Koi Fish owners,  Koi Fish supplies store, and articles about how to take care Koi Fish. Visit our website frequently to check out our latest article because we will post more guides to help you be a better Koi parent.

No matter how much you know about koi fish there are always more story to be shared! There are so many interesting things to learn about koi fish that you should learn something new with these 5 koi fish’s history knowledge.

 

 

 

1.Koi fish were originally brought to Japan as a food source

Koi natural habitats in the Black, Caspian, and Aral seas in Asia, and China is the true beginning of Koi fish. According to Chinese history, Confucius’s son was given a mutated carp by king Shoko of Ro and from then on the fish became the subject of many Chinese artwork. When the Chinese invaded Japan, these carp were breed as a food source due to their resilient nature, this was the beginning of the Japanese Koi fish. Koi (in japanese means carp) were first bred in Japan in the 1820’s, initially in the town of Ojiya, Japanese perfecture of Niigata. While they were still being bred for food, these brown fish occasionally produced red and blue mutations. Through selective breeding, the red and white variety  – recognizable as the modern ornamental koi – was eventually perfected in 1870. The outside world was unaware of the development of color variations in Japanese koi until 1914, when the Niigata koi were exhibited at an annual exposition in Tokyo. From that time, interest in koi spread throughout Japan. More than 100 color varieties have been bred from this single species of fish, including a scaleless variety in Germany now known as the mirror or Doitsu-goi/German carp.

 

2.Koi fish are descendent’s of the hardy common Carp which is so adaptable and it can be found all around the world

The common carp is a hardy fish, and koi retain that durability from it. Koi are cold-water fish, but benefit from being kept in the 15–25 °C (59–77 °F) range, and do not react well to long and cold winter temperatures. Their immune systems are very weak below 10 °C. Koi ponds usually have a meter or more of depth in areas of the world that become warm during the summer, whereas in areas that have harsher winters, ponds generally have a minimum of 1.5 m (5 ft).

 

3. Koi fish were developed by Japanese farmers

Koi in the nature have a brown color,but through selective breeding by the Japanese, numerous colors and patterns were developed. In the 17th century, Chinese rice farmers began keeping carp in their rice paddies as a food fish. This practice found its way to Japan. The Japanese rice farmers begin to notice slight color variations in a few of the carp and they saw great potential to bring out their vibrant colors. Therefore, the farmers bred these carp into what eventually became what we know today as Nishikigoi.

 

4. Koi fish were brought to the worlds attention after one was given to the Japanese emperor as a gift in 1914 to grace the imperial palaces moat

The popularity of the Japanese Koi fish quickly grew, though other countries had yet to truly notice these lovely fish, and soon it was the most desired fish in the country. Koi fish became so popular in Japan that it was considered a perfect gift for Emperor  Hirohito’s imperial palace moat in 1914. This presentation caught the eyes of every county in the world and soon after the Japanese Koi fish had caught the hearts of millions.

 

5. Koi fish and Goldfish are distant cousins as they both decent from Carp, but goldfish came about long before koi fish did.

Goldfish

Ooh, this koi is so perfect!!!

Koi fish

Both koi fish and goldfish are descedents of carp so they are actually distant relatives. The goldfish is far older than koi fish. Goldfish were developed in China over 1,000 years ago while koi fish have only graced our ponds since the 1820’s. Koi and goldfish show there similarities and differences in their color, body shape, and lifespan.
