Everything You Need to Know About Kujaku Koi

Koi are a type of fish that is native to Japan and typically kept as pets or ornamental fish in outdoor ponds. They are the descendants of the common wild carp and come in a variety of vibrant colors and patterns, with the kujaku koi being one of the most popular and sought-after varieties.

Kujaku koi are characterized by their beautiful net-like design on a platinum body similar to that of the Asagi. This is complemented by either yellow, orange, or red patterns for an eye-catching impact. In this article, we'll take a closer look at Kujaku koi, their history, and what sets them apart from other koi varieties.

What Is a Kujaku Koi?

Kojaku Koi is one of the most beautiful types of koi fish. The complete name for the breed is Kujaku Ogon, which means "peacock" in Japanese and refers to the koi itself, which is often called a Peacock koi.

A Kujaku koi is a striking koi characterized by heavy black reticulation across the scales, giving the fish a net-like appearance running down its back. This reticulation is then topped with a Kohaku-style pattern in red, orange, yellow, or gold to create a very dramatic effect.

Origin

The Kujaku variation is the result of selective breeding. This beautiful fish was first created by crossing Goshiki with an Ogon Koi. The result is a Koi Carp with a solid metallic white background or base skin color, accentuated with a much darker almost black scale reticulation or net-like pattern.(Known as Fukurin).

It was originally categorized under Hikarimoyo. In recent years, with their growing popularity, the Kujaku (literally "Peacock") have been evaluated in a category of their own.

Meaning

The meaning of Kujaku koi is 'peacock'. This is because of their solid white foundation, complemented by black net designs and red/orange/yellow markings. Each scale has a black edging that produces the net pattern.

Size

This magnificent variety of koi can reach quite big proportions. The average size of a Kujaku koi is between 24 and 36 inches long, however, they can grow up to 4 feet in length if provided with ideal circumstances.

Lifespan

Kujaku koi have a lifespan of around 25-35 years, though some individual fish have been known to live for 40 years or more. The lifespan of a Kujaku koi depends on several factors such as the quality of water in which they are kept, their diet, and whether or not they contract any diseases.

Behavior and Temperament

Kujaku Koi is typically gentle and easygoing fish like any other traditional koi variety. They get along with other koi varieties as well as other types of fish, making them a good choice for community ponds.

They're also known to be very nosy, frequently swimming up to the pond's edge to investigate any new sightings or noises. They'll come out and eat out of your hands after getting used to their caretakers.

While Kujaku is not known to be aggressive, they can be territorial when it comes to feeding time. It is therefore important to provide them with plenty of food so that everyone gets their fair share. They are also observed to be aggressive during the mating season.

When startled, koi respond in different ways. They get stressed when they're exposed to new or unfamiliar problems. They also despise abrupt shifts, especially if you move them into a new pond or tank or fluctuate the temperature rapidly. A stressed koi may miss out on a meal by hanging near the bottom of the pond instead of eating.

Finally, if they are speeding around the pond or acting sluggish, they may be ill. If their formerly graceful swimming has become ungainly and uncoordinated, they may be unwell.

A stressed koi fish will usually succumb to sickness since stress degrades the immune system. While each disease will have its own set of symptoms to look for, a general deterioration in health is usually the first sign that something is wrong.

Variations of Kujaku Koi

Variations of Kujaku Koi

Kujaku koi are known for their beauty and elegance. They can be found in a variety of colors and patterns, each one more stunning than the next. There are mainly three types of Kujaku koi:

Doitsu Kujaku Koi 

The term Doitsu is used to describe koi without scales, with the exception of enlarged scales on the lateral line and two lines running alongside the dorsal fin. The Doitsu Kujaku will have a black net pattern and red/orange/yellow patterns, but their skin will be smooth and glossy.

Tancho Kujaku Koi 

Tancho Kujaku is gorgeous snowy white color koi. They have a large Hi marking on their white head. The position of the Hi marking is very important and should be well-defined and symmetrical. Between the eyes and the nose, the circular high needs to be as large as possible. Tancho Kujaku refers to a koi fish with a net-like body design, with a huge circular high marking on its head.

Maruten Kujaku Koi

Tancho is an exciting variety of koi with only one Hi (or red hue) pattern on its head. But when a koi has a circle spot on the head like Tancho and still possesses some Hi pattern on the body, it's not called Tancho; it's called Maruten. A Maruten Kujaku is a black-net-patterned koi with a single red dot on the head and red, orange, or yellow hues on the rest of the body.

Gin Rin Kohaku Koi

The name "Gin Rin" refers to the silver scale variety of freshwater fish, and it's easy to understand why since this type of scale reflects light. A koi with a white platinum base and yellow, orange, or red patterns with sparkling silver-colored scales is referred to as a "Gin Rin Kohaku".

What Makes a Good Kujaku?

There are several factors to consider when evaluating the quality of a Kujaku koi. Because the koi will combine elements of many different, older varieties of koi, the finest quality Kujaku should exhibit the best elements of each. So how do I choose a koi Kujaku? The following are the key characteristics to look for:

  • Head shape: The head of a Kujaku koi should be large and well-proportioned to the body. The snout should be short and blunt, with the nostrils placed close together. The lips should be thick and fleshy, but not so much that they obscure the mouthparts. These things make a koi fish head look beautiful.
  • Body type: Keep in mind the shine and luster of the koi's skin. Because Kujaku is a shinny metallic koi, it is critical that its skin does not look dull. If you have a bright and glossy Kujaku, it will stand out in your pond and be instantly noticed, but a dull Kujaku will go unnoticed.

  • Quality of reticulation on the scales: The beautiful net-like pattern along the back of the Kujaku koi is provided by this reticulation. The Kujaku high quality koi will have uniform reticulation thickness all over, and it should not have thin reticulation in one area of the body and thick reticulation in another. When the reticulation is consistent throughout, you'll have a lovely-looking koi that any koi keeper would be pleased to own in their pond. However, it all depends on one's personal preference.

  • Colorations on the koi: There are a few things to consider when picking the color variety of a Kujaku. Firstly, we can consider the base color. In a Kujaku, that is white and should be a beautiful clear snow-white skin color. A clean white skin ground contrasting with a bright hi coloration can result in a beautiful and stunning koi fish. The next color to consider is the Hi, or the red. This can be any shade of red – a deep, bright red is favorable for some, and a fiery orange is favorable for others. The important thing is that the color is even with a consistent shade through the fish and must have strong, clear, and sharp edges. Unbalanced fish markings will have a negative impact on your koi fish. So, always consider the quality of the colorations on the koi if you are looking for a top-quality Kujaku.

Habitat

Kujaku Koi is beautiful and peaceful creatures that make a stunning addition to any pond or water feature. But before you add them to your home, it's important to do your research and understand their unique needs.

Kujaku Koi thrives in water temperatures ranging from 59 to 77 degrees Fahrenheit, which makes them cold-water fish. Because their metabolism is dependent on the temperature of the water they live in, you'll need to be sure your pond has both shallow sections and deep areas that don't freeze to the bottom. It must be at least 3 feet deep to support a Kujaku koi's growth and development.

Kujaku Koi is also very social creatures, so you'll need to have at least three or four of them in your pond. However, make sure not to overcrowd your pond, as this can lead to health problems. Aside from this, there are a few additional criteria to consider before adding Kujaku koi to a pond habitat.

Shade to Sun Ratio

Shade to Sun Ratio

Kujaku Koi requires a pond that ranges in temperature from 70 to 80 degrees Fahrenheit, and water that becomes too hot might be stressful for them. To make sure your Kujaku Koi don't get too much sun, have at least 50% of your pond's surface area covered in shade.

Kujaku Koi are vulnerable to being eaten by cats, foxes, raccoons, otters, kingfishers, herons, badgers, and other animals since their brilliant hues attract them. Shading a pond as well as an effective design plan can aid prevent predators from seeing in easily or reaching into the water to harm fish.

Dissolved Oxygen Levels

It's critical to test your pond water and check for dissolved oxygen levels on a frequent basis as a Kujaku koi keeper. Dissolved oxygen is the amount of oxygen in the water that can be utilized by aquatic life.

When the amount of dissolved oxygen in a pond drops below 4 to 5 milligrams per liter, it can be detrimental to pond fish health and has been linked to poor fish growth, ongoing illness, parasite infection, and bacterial infections. Levels below 2 milligrams per liter are particularly harmful, and in many situations will kill your Kujaku koi.

Dissolved oxygen levels between 7 and 9 milligrams per liter of water are required for pond fish to thrive. Warm water does not deliver as much oxygen as cool water, so koi require more oxygen in higher temperatures when they are active and eating more frequently.

A waterfall or fountain can enhance the oxygen level in a confined pond. A supplementary aeration system, on the other hand, is advised for ponds with a depth of more than 4 feet. If you're aerating your pond in the winter, you'll need to create a tiny hole or outlet for the bubbles to escape from the surface of your partially frozen pond so that they don't become trapped and cause your fish to suffocate.

Ph Levels 

A Kujaku koi's ideal pH level is between 7.0 and 8.4, with 7.4 being the optimal number. The pH is a measurement of how alkaline or acidic the water is. A low pH level indicates that the water is acidic, while a high pH level means that the water is alkaline.

If the pH of your pond's waterfalls is outside of this range, it can create stress for your fish and make them more susceptible to disease. To maintain a stable pH level, you'll need to test your water regularly and make adjustments as needed.

You can raise the pH level of your water by adding limestone or sodium bicarbonate, and you can lower the pH level by adding sulfur or peat moss.

Ammonia and Nitrite Levels

Another important aspect to consider when caring for Kujaku koi is the levels of ammonia and nitrites in your pond water. Ammonia is produced by the breakdown of fish waste, uneaten food, and decaying plants. Nitrites are produced by bacteria that feed on ammonia.

Both ammonia and nitrites can be harmful to koi at high levels, so it's important to test your pond water regularly and take steps to keep the levels low.

You can lower the ammonia and nitrite levels in your pond by adding bacteria that will consume them. You can also reduce the amount of waste produced by feeding your fish only as much as they can eat and removing uneaten food from the pond.

Plants 

Kujaku koi appreciate having plants in their pond, both for the aesthetic value and the practical benefits. Plants help to oxygenate the water, provide shelter for fish, and help to keep the water clean. If you don't want to take care of debris often then placing artificial pond plants is suggested. 

Some good plants to consider adding to your pond include water lilies, irises, lotuses, cattails, and rushes. When choosing plants for your pond, be sure to avoid those that are known to be invasive or poisonous to koi.

Diet

Koi fish are omnivores that prefer a combination of plant-based and meat-based diets. Koi fish developed from Wild Carp, which are bottom-feeders in the wild. Koi feed almost entirely on plant matter that sinks to the bottom of their body of water in the wild. They also consume tiny arthropods, algae, crustaceans, zooplankton, and other invertebrates that dwell in or around the sediment.

Koi are not picky eaters; however, the diet of your koi should be well-rounded and nutritious, providing them with the essential nutrients they need to grow and thrive. A good quality koi food will contain all of the necessary vitamins, minerals, and proteins that your koi need. You may also offer your koi live foods such as worms, larvae, or tiny fish in addition to pellets or granules.

What to Feed Your Kujaku Koi Fish?

Feeding the right type of food is just as important as providing a well-rounded and nutritious diet. There are many different types of koi food on the market, and it can be difficult to know which one is best for your koi. Here is a list of common Kujaku Koi foods and what they contain:

Pellets or granules: Pellets or granules are a type of dry food that contains all of the essential nutrients your koi need. They are available in a variety of formulations, such as growth formulas, color-enhancing formulas, and all-purpose formulas.

Wafers: Wafers are a type of dry food that sinks to the bottom of the pond, making them ideal for koi that prefer to feed on plant matter. It has a similar nutrient profile to pellets or granules.

Flakes: Flakes are a type of dry food that floats on the surface of the water, making them ideal for koi that prefer to feed on tiny arthropods and other invertebrates that dwell near the water’s surface.

Live food: Live food, such as worms, larvae, or tiny fish, is a type of food that koi enjoy and can be a nutritious addition to their diet. They are rich in protein and other nutrients but should be fed in moderation as they can contain harmful parasites that can infect your koi.

Frozen food: Frozen food, such as bloodworms, daphnia, or brine shrimp, is another type of live food that koi enjoy.

Vegetables: Vegetables, such as peas, lettuce, or spinach, can be given as a treat or supplement to koi. A vegetable diet for koi has the following advantages: Improved digestion, greater nutrient absorption, and reduced risk of constipation. There are many vegetables that are safe for koi to eat, but some, such as cabbage and broccoli, can cause indigestion.

Fruits: Orange slices, grapes, and watermelon are among their favorites. Feeding your fish these goodies might help reduce tension as well as boost their immune system in addition to being enjoyable to observe.

Cooked rice or pasta: Cooked rice or pasta can be offered to koi as an occasional treat. However, avoid feeding them cooked rice or pasta that contains salt, fat, or other spices as these can be harmful to their health.

Shade to Sun Ratio

What Not to Feed Your Kujaku Koi Fish?

There are a variety of meals that your koi can consume that are high in nutrients, vitamins, and minerals. There are, however, certain products that should be avoided. The following is a list of foods to avoid:

  • Bread: Bread is a common food that people like to feed to ducks and other waterfowl, but it is not good food for koi. Bread is high in carbohydrates and can cause indigestion in koi.
  • Uncooked Meat: Uncooked meat, such as chicken or beef, can contain harmful bacteria that can make your koi sick. In addition, uncooked meat is high in fat and can cause obesity in koi.
  • Dairy Products: Dairy products, such as milk or cheese, can spoil quickly and contain harmful bacteria that can make your koi sick.
  • Canned Food: Canned food, such as tuna or sardines, can contain high levels of mercury that can be toxic to koi. In addition, canned food is often high in salt, which can be harmful to koi.
  • Human Food: Human food, such as chips or candy, is not good for koi. These foods are often high in fat, salt, or sugar, which can be harmful to koi.

How Much and How Often to Feed Your Koi?

Feeding koi is not an exact science, and there is no one-size-fits-all answer to this question. The amount and frequency of feedings will vary depending on a number of factors, such as the type of food being fed, the water temperature, the koi’s life stage, and the koi’s activity level. In general, it is best to start with a small amount of food and increase the amount as needed. It is also important to avoid overfeeding, as this can cause water quality problems and make your koi sick.

As a rule of thumb, koi should be fed 2-4 times per day. If you are feeding pellets or granules, you should offer enough food so that the koi can consume it all in 2-3 minutes. If you are feeding live food or frozen food, you should offer enough so that the koi can consume it all in 5 minutes.

It is also important to note that koi have a natural tendency to overeat, so it is important to avoid overfeeding. Overfeeding can cause water quality problems and make your koi sick.

Note: After feeding your koi, it is important to remove any uneaten food from the pond. Uneaten food can decompose and cause water quality problems. In addition, uneaten food can attract unwanted pests, such as rats or mice.

Breeding 

Breeding koi can be a gratifying experience. It can also be quite time-consuming. However, nothing compares to raising your own koi successfully. This rewarding hobby needs certain prerequisites. You'll soon have a collection of cute koi babies if you know the procedures, have the equipment and have the time.

Kujaku Koi Conditioning Tips

Koi reach sexual maturity at about three years old. Select the healthiest and strongest fish from your pond. These are the koi that will produce the best offspring. You must condition the fish after selecting the parents in order for them to spawn. Follow these tips to do so:

  • Provide a good diet- A well-balanced diet is essential for koi health and plays an important role in the spawning process. Make sure you are feeding your koi a high-quality food that is rich in vitamins and minerals. Feed them high protein food 4-5 times per day, it's important to increase the frequency of feedings. This will help stimulate their appetite and get them ready for spawning.
  • Appropriate water condition-Another approach to stimulate spawning is to maintain the proper water conditions. The right surroundings should be created in which they would experience similar weather and terrain as their natural habitats. It's critical to use a tank that provides enough "secrecy," hiding places. The water flow, lighting, and temperature should also be considered.
  • Repeating the process-Reduce the aquarium's water level by half. Add 5% of the aquarium's volume each day. Every day, add a mix of soft water that is somewhat cooler than the aquarium water. A drip line or a spray bar will add to the illusion. Your Kujaku Koi should be repeatedly fed during this period. This procedure may be repeated until fish begins to exhibit spawning symptoms. Most fish react positively to a change in water quality, such as soft or altered water temperature.
Kujaku Koi Breeding Tank Set Up

Kujaku Koi Breeding Tank Set Up

You will need to set up a breeding tank before you can start the spawning process. The following tips will help you set up the perfect breeding environment for your Kujaku koi:

  • Choose a tank that is at least 50 gallons in size. It should be deep enough to allow the female koi to lay their eggs without being disturbed.
  • The tank should be equipped with a filter and an air pump. The water should be kept clean and well-oxygenated.
  • Fill the tank with water from your pond. The water should be of the same temperature and quality as the pond water.
  • Add some live plants to the tank. Koi like to hide among the plants. Java moss is a good choice for a breeding tank.
  • To protect the koi spawn, predictors and debris should be removed from the pond. This can be done with the help of a skimmer net or a comparable scoop tool.
  • Place a fry mat in the pond. This is a smooth and sticky mat that serves as a nesting site for the koi. Place the mat at the bottom of the pool in an obvious location.
  • Prepare a separate tank for the adult koi. If you wish to breed a large number of koi, it's critical to get rid of the adult fish since they will eat many of the eggs. Ensure that the aquarium is clean and equipped with a filter system before adding any fish.

Kujaku Koi Spawning

Kujaku Koi multiplies when the weather (or tank) warms up. It's difficult to pin down a precise “season,” because optimal conditions may differ from nation to nation, state to state, and even among the fish themselves.

When the water temperature reaches 68°F or above in most regions, koi become very active and their metabolism speeds up. This is when they are most likely to spawn.

To start the spawning process, you will need to condition the Kujaku koi as previously mentioned. The male Kujaku usually becomes very excited during this time and will chase the female Kujaku koi around the tank. The female will lay her eggs on the fry mat or among the plants. After spawning, the male will release his milt (sperm) to fertilize the eggs.

The number of eggs laid by a Kujaku koi can range anywhere from several hundred to several thousand.

Tips to Care for Kujaku Koi Fry

  • The Kujaku Koi eggs will hatch after about 4 days. The fry will be very small and delicate. There is no need to feed the fry for the first 10 days as they will live off their yolk sacs.
  • After ten days, feed the baby Kujaku koi powdered koi pellets. Kois pellets should be crushed using a blender or mortar and pestle until they are a fine powder. Sprinkle the powder over the pond. Pour in enough powder to last 5 minutes for the fish. Feed the koi four times each day
  • Continue to offer the baby Kujaku koi powdered food until they are four weeks old. You will figure out how much food the baby koi require during each 5-minute feeding session over time. It might take a few days for the Kujaku koi to get used to eating powdered food.
  • Increase the size of the food once your Kujaku koi is one month old. Start mixing crumb-size pellet pieces into their diet when your koi are four weeks old. You'll still need to smash the pellets, but they don't have to be in a fine powder anymore.
  • Cull any weakfish so as to not overstock the pond. You should also remove any fish that have deformities. Koi may be culled at any age, however, it is preferable to wait until their characteristics develop so you can decide which ones to keep.
kujaku-Diseases

Diseases

Kujaku is no exception to the rule that all types of fish are vulnerable to a variety of illnesses. The most prevalent diseases affecting Kujaku are caused by:

  • Parasites- Some of the most common parasitic diseases are Ich, Fish Lice, Trichodina, Chilodonella, and Costia. They can be treated with a variety of methods, but the most common is to raise the temperature of the water and treat it with salt.
  • Bacteria- There are many different types of bacteria that can infect Koi. The most common are Aeromonas, Pseudomonas, and Mycobacterium. Some of the most common bacterial diseases include Dropsy, Fin Rot, and Mouth Rot.
  • Fungus- The most common type of fungus is Saprolegnia. It usually affects fish that are weak or have recently been injured. The best way to treat it is to raise the temperature of the water and add an anti-fungal medication.
  • Worms- Commonly found in koi are roundworms, tapeworms, anchor worms, and flukes. These worms can cause serious health problems for your koi, and some of them can even be fatal. The best way to treat worms is to use a medication that will kill the worms without harming the fish.

Symptoms 

It can be very easy to miss the early signs of disease in your koi. This is why it is important to check your fish regularly for any changes in their appearance or behavior. Some of the most common symptoms include:

  • Loss of appetite
  • Gasping for air
  • Listlessness
  • Clamped fins
  • Hanging at the surface of the water
  • White spots
  • Discoloration or faded color
  • Rubbing against objects

Fixing the Cause of the Diseases

Even though there is no surefire way to prevent your koi from getting sick, there are some things you can do to reduce the risk. Some of the most important things you can do are:

Quarantine new fish before adding them to your pond

Regularly clean your pond and remove any debris

Keep your pond well aerated

Change at least 20% of the water each week

Feed your koi a high-quality diet

Provide them with a clean and safe environment

Make sure you have the right number of koi fish-Do not overcrowd

Get your koi fish from a reputable source
