Guide to Bekko Koi Varieties, Care, Size, Diet

Koi carp have been around us for hundreds of years. Because of their distinct appearance, they are quite popular and look fantastic in any pond or water garden. Kois are very peaceful fish, and they range in size from a few inches to several feet long. There are many different varieties of this amazingly beautiful fish, and each has its own unique coloration and pattern. The bekko koi is one such variety.

Bekko koi is a beautiful variety that is characterized by its black and white coloration. Even though these are hardy fish, they do require some care and attention in order to thrive. In this article, we will take a look at everything you need to know about Bekko koi, including their appearance, care requirements, diet, and more.

What is Bekko Koi? 

The Bekko is a black-spotted solid-colored non-metallic koi fish. They come in mainly three colors, white, red and yellow. The white is called Shiro Bekko, red is called the Aka Bekko koi, and yellow is called Ki Bekko.

The Bekko is generally one of the first varieties that a beginner koi hobbyist learns to recognize and is a very popular fish for Japanese koi ponds and water gardens. They are very beautiful koi fish that can add a touch of elegance to any pond or water garden.

Bekko Koi Origin 

The first Bekko koi was unintentionally created in the mid-nineteenth century while breeding Taisho Sanshoku koi, also known as Sanke. Because koi breeding is so intricate and fickle, and these two breeds are quite similar, it's almost certain that two Sanke will have some Bekko offspring. However, unlike Sanke which has three colors on its body - two base colors and Sumi - Bekkos only possesses two, one base color and Sumi.

Bekko Koi Meaning 

In Japanese, "Bekko" is a rough translation for "separate," but it's probably more accurate to say it means "tortoiseshell." The two-toned pattern and coloration of this variety of koi are meant to resemble the beautifully mottled shells of certain turtles.

Size

This amazing koi fish can grow quite large, sometimes reaching lengths of up to three feet or more. However, the average size of a Bekko koi is usually between twenty and thirty inches. But sometimes, they can grow even larger than that. This will depend on the conditions in which they are kept, their diet, and genetics.

Lifespan 

Bekko koi are well known for their long lifespan. In fact, these koi can easily live for twenty years or more. But in order to reach their full potential, they need to be kept in optimal conditions and given the best possible care. There are some koi that can live for over fifty years, but this is quite rare.

Bekko Koi Colors

Bekko Koi Colors

As we mentioned before, Bekko koi come in three main colors - white, red, and yellow. The white Bekko is called Shiro Bekko koi, the red one is called koi Aka Bekko, and the yellow one is called Ki Bekko.

The most popular color of Bekko koi is probably the white Shiro Bekko. These fish are incredibly beautiful, and their black spots contrast sharply against their snowy white background. However, the yellow or Ki Bekko is considered the rarest among the three.

Bekko Koi Varieties

Bekko koi are very beautiful koi fish, and they come in a wide variety of colors and patterns. Some of the most popular Bekko koi varieties include the following:

  • Shiro Bekko- This is the most popular variety of Bekko koi, and it's characterized by its jet black spots on a snow-white background. They are absolutely stunning fish, and they are sure to add a touch of elegance to any pond or water garden.
  • Aka Bekko- Aka Bekko is the name of the red variety. It's a beautiful koi with a deep red coloration and black spots on its body. They are quite common and are often seen in koi ponds and water gardens.
  • Ki Bekko- The yellow variety of Bekko is called as the Ki Bekko. It's a beautiful koi with a deep yellow coloration and black spots on its body. They are quite rare and are not seen as often as the other two varieties.
  • Doitsu Bekko- Doitsu Bekko are scaleless and smooth, just as other Doitsu koi are. They can be Aka, Shiro, or Ki color variations. Doitsu Bekko is quite uncommon in general; however, the rarest is the Ki Bekko variety.
  • Gin Rin Bekko- Gin Rin Bekko is a type of Bekko koi fish that has sparkling scales, similar to the Gin Rin variety of other koi types. They can be Aka, Shiro, or Ki color variations.

Tips to Choose the Perfect Bekko for Your Pond

Bekko Koi is one of the most popular koi fish varieties, and they come in a wide variety of colors and patterns. When choosing Bekko koi fish for your pond, it's important to take into account the following tips:

  • When assessing a Bekko koi fish, the position of the Sumi is crucial. The Sumi patches on a Bekko must appear uniformly across the back of the Koi. They should never be positioned ahead of or behind the shoulder area.
  • The Bekko head should not have any black pigment, spots, or pattern.
  • The fin should be white with Sumi zigzag stripes, which may help to maintain the Sumi pattern's equilibrium.
  • The fish should not have anything wrong with them, such as missing fins, deformed mouths, or bruising.
  • Symmetry is also significant. The Sumi should be evenly balanced and symmetrical in their orientation from front to back and side to side.
  • A well-shaped fish has a proportional, symmetrical head with proportionate, symmetrical fins and a torpedo-shaped body.
Habitat

Habitat 

Bekko koi are freshwater fish, and they need to be kept in a freshwater habitat. They can be kept in ponds, tanks, or aquariums; however, they prefer to live in ponds. Ponds provide them with plenty of space to swim and explore, and they also offer a more natural environment.

While setting up a habitat for your Bekko koi, it's important to take into account the following factors:

  • Koi can grow very big in a matter of months. Keep mature koi in an outdoor pond with at least 3 feet of depth and 50 gallons of water per fish. Koi can be kept in an aquarium no larger than 29 gallons if they are young.
  • Put the aquarium in a quiet area out of direct sunlight and drafts as koi are very sensitive to changes in water temperature.

  • Aquariums and ponds should have a filtration system to keep the water clean and free of toxins. Other koi-keeping equipment you'll need includes a water pump, air pump, and aerator.

  • Bekko koi, like other koi, require water temperatures of 50° F to 78° F (10° C-25° C), pH levels of 7.5 and 8.5, dissolved oxygen levels of 7 parts per million (ppm), salinity levels of .05 to .15 parts per trillion (ppt), and a water hardness of 5 to 15 dH.

  • Bekko Koi are very sensitive to changes in their environment, and even small fluctuations can cause them stress. It's important to keep a close eye on the water quality in their habitat and make sure that it remains stable.

  • Bekko Koi are social creatures and do best when living in groups. It's important to have at least 3-5 koi in your pond or aquarium so they can interact with each other.

  • Provide your Bekko koi with plenty of hiding places in their habitat. They like to have a lot of plants and rocks to hide behind when they're feeling scared or stressed.

Diet 

Bekko Koi are omnivores, and their diet consists of both plant and animal matter. In the wild, they eat a variety of aquatic plants, algae, small insects, and crustaceans. In captivity, they can be fed a healthy diet of pellets, flakes, live food, and frozen food.

The food you provide must include the following:

  • Vitamins and minerals- Bekko koi require a diet that is rich in vitamins and minerals. This will help them to stay healthy and maintain their color. Some of the foods that are high in vitamins and minerals include pellets, flakes, live food, and frozen food.
  • Protein- Bekkos require a high-protein diet. This will aid in their development and maturation. It will also help in healthy weight gain. Foods such as pellets, flakes, live food, and frozen food are all high in protein. Other foods that are high in protein include insects and crustaceans.
  • Fiber- Bekkos also require a plant-based diet that includes both fruits, and vegetables. This will help them to stay healthy and prevent many common diseases. Some of the best sources of fiber in a vegan diet include lettuce, cucumber, and spinach.
  • Fatty acids- Fatty acids are essential for the health of all koi, including Bekko koi. They help to keep the skin and scales healthy and also aid in digestion. Foods that are high in fatty acids include pellets, flakes, live food, and frozen food.
Foods to Avoid

Foods to Avoid 

It's important to understand what not to feed your Bekko koi. Anything high in carbohydrates should be avoided by Bekko koi owners. Bread, which is often regarded as a safe indulgence, can actually be detrimental to Bekko koi. The yeast in bread might cause bloating and gastrointestinal problems.

Bekko koi are also affected by chips since they are high in salt and fat. Both obesity and heart disease can be caused by the presence of both of these factors. Cookies and candies should be avoided because they are rich in sugar and calories. They are also known to increase body fat.

Don't offer them anything you've caught in the wild, either. They may have parasites or illnesses. This may not seem harmful to you, but it could be very dangerous for your koi.

Grains aren't the greatest food for koi. They're often high in fat, which is ideal if your fish start to lose weight. If you give them pasta or rice, prepare them without salt first. Otherwise, the meal might swell in the stomach due to excessive salt intake.

Feeding Tips

  • Bekko Koi should be fed 2-3 times a day. This will ensure that they are getting all the nutrients they need.
  • When feeding Bekko koi, it's important to remember that they are very messy eaters. They tend to scatter their food around, and this can dirty the water very quickly. It's important to have a good filtration system in place so that the water doesn't become too dirty. Remove the uneaten food from the habitat after each feeding.

  • Overfeeding is a very common problem among koi keepers. It's important to only feed your Bekko koi as much as they can eat in 2-3 minutes. Any more than that will just end up polluting the water.

  • The optimum time to feed koi fish is when water temperatures are at least 86°F (30°C), whether it's in terms of weather or season. Water temperatures between 68°F and 86°F are when koi fish are most active, meaning they may require up to four feedings a day. Water temperatures drop below 68°F (20°C) at this time, slowing down koi fish's digestive systems. You should only offer your koi once or twice a day by now. Any temperature lower than 68°F (20°C) might lead you to believe that your koi will not eat. They're most likely hibernating.

  • Do not feed your koi when the water temperature is below 50°F (10°C) as this can be fatal to them.

  • Koi food comes in different shapes, sizes, and colors. The type of food you choose should be based on the size of your koi and their feeding habits.

Breeding

Bekko is a beautiful koi that come in a wide variety of colors and patterns. While they are not the easiest koi to breed, the process can be rewarding. So how to breed Bekko Koi? Here are some tips that might help.

Selecting the Breeding Pair

The first thing you need to do is make sure that you have a male and a female koi. You can tell the difference by looking at their vents. The male's vent will be elongated and pointy, while the females will be rounder. To increase your chances of success, it's best to start with high-quality, healthy fish. Make sure the fish you select are well-fed and free of parasites and disease.

You'll also need to make sure that the koi are of breeding age. The female should be at least 2 years old, and the male should be 1 year old. If they're younger than this, they might not be ready to breed yet.

Conditioning

The next thing you need to do is condition the koi for breeding. This means getting them used to the idea of eating live food. You can do this by feeding the koi some live brine shrimp or daphnia. This will help them get in the mood for breeding.

You should also start making changes to their diet. Start feeding them more protein and fewer carbohydrates. This will help them build up their energy reserves for the breeding process. Increase the amount of food as well as the number of feedings.

You should also start making changes to the habitat. The water should be a little warmer than usual, around 78-80 degrees Fahrenheit. This will help trigger the spawning process.

Breeding Tank Set-Up 

You'll need to set up a breeding tank before you can start the breeding process. The tank should be at least 50 gallons, and it should have a good filtration system. It's also a good idea to add an air stone to help aerate the water. Clear the debris from the bottom of the tank.

The water should be around 78-80 degrees Fahrenheit, and the pH should be between 7.0 and 8.0. The ammonia and nitrite levels should be zero, and the nitrate levels should be below 20 ppm.

You'll also need to add some plants to the tank. Java moss is a good option because it's easy to grow and koi like to eat it. You can also add some floating plants to help reduce the amount of light that enters the tank. Place a fry mat on the bottom of the tank. This will help protect the eggs when they're laid.

Spawning

Spawning 

The spawning process starts with the male koi chasing the female around the tank. It is very important to check the male and female from time to time during this time, as the process may get a little bit aggressive resulting in one or both of the koi getting injured. If this happens, you'll need to remove them from the tank and try again another time.

When the female is ready to lay her eggs, she will stop and allow the male to approach her. He will then nudge her belly with his nose, and she will release her eggs onto the fry mat. The process can take anywhere from a few hours to a few days.

The number of eggs that are laid can range from a few hundred to a few thousand.

Caring for the Eggs

Once the eggs have been laid, you'll need to remove the parents from the tank. They will eat the eggs if they're given the chance.

You'll also need to remove the fry mat from the tank and put it in a separate container. Fill the container with water from the breeding tank, and add an air stone to help aerate the water. The temperature of the water should be around 80 degrees Fahrenheit.

The eggs will hatch in about 3-7 days.

Bekko Koi Fry Care 

Caring for Bekko koi fry is not difficult, but it does require some patience. The fries are very small and delicate in the early stages, so you'll need to take care not to damage them.

For the first few days, you don't need to worry about feeding them. They will live off of the yolk sac attached to their belly. After a few days, you will have to start feeding them. They will eat anything that's small enough for them to fit in their mouth, including brine shrimp, daphnia, and micro worms.

You can also purchase commercial fry food such as pellets from your local pet store. Always remember to crush the food into small pieces before feeding it to the fry.

As they grow, you can start feeding them larger foods such as bloodworms and tubifex worms. You can also give them pellets that are designed for koi fry. The fry will need to be fed several times a day.

To keep the water clean, you'll need to do partial water changes every day. Remove 10-15% of the water and replace it with fresh, clean water. Water changes will need to be done every day for the first few weeks. After that, you can start doing them every other day.

As the fry grows, you'll need to move them to a larger tank. A 20-gallon tank is a good size for koi fry. You can also add some plants and rocks to the tank to help them feel more comfortable. Be sure to remove any plants that have sharp edges, as the fry can get hurt on them.

When the fry is about 4-6 inches long, you can start moving them to an outdoor pond. They will need to be acclimated to the change in temperature and water quality, so do it slowly over the course of a week or two.

As the fry grows, they will start to develop their color patterns. This process can take several months. Once they reach adulthood, this koi variety will be between 18 and 24 inches long.
