Koi Fish

Nishikigoi Koi Fish are Japanese Koi Fish that are distinguished by their coloration, patterning, and scalation.

They are also characterized by their graceful swimming, beautiful color variation, and exquisite body conformation. In addition to their beauty, these fish are known for their unique charm.

Nishikigoi fish were originally farmed in Niigata and are considered a living art. Today, they are prized ornamental fish that are prized by collectors worldwide.

Their colorful beauty makes them a desirable addition to any koi collection. They are also known as hanagoi and irogoi.

Nishikigoi are raised in outdoor and indoor tanks and evaluated for their brightest patterns.

Historically, Nishikigoi were bred from carp over a thousand years ago in China for their color mutations. Their vibrant colors led to the development of goldfish.

Nishikigoi is relatively rare in Japan, but are becoming increasingly popular. The Japanese government estimates they will produce Y4.7 billion worth of ornamental fish annually by 2019.

While they are still relatively rare, nishikigoi are now popular among wealthy foreigners.

Nishikigoi’s beautiful colors result from the pigments in their skin cells.

This pigmentation makes the dark ocean water appear blue; the same is true for koi skin. It is similar to the water prism effect that makes the dark bottom look blue.

The koi skin mimics this effect, creating a blue color. This gives a unique look and feels to your water garden.

Koi have many varieties, but Nishikigoi Koi is one of the oldest. Breeders have incorporated advanced breeding techniques to produce many new varieties of koi.

The different types of Nishikigoi differ in color, patterns, and scales. Some varieties are older than others, while others are a hybrid.

Nishikigoi is extremely popular and can be bought for as little as Y=500. As long as you keep them in water, you’ll never go wrong with one of these amazing fish.

With the right care, they’ll grow to be healthy and strong, resulting in an excellent addition to any pond.

Nishikigoi Koi Fish is a colorful variety of Amur carp, which means “brocaded carp.”

They are commonly kept as ornaments in water gardens and outdoor koi ponds. Their beautiful colors and vivid patterns make them the perfect addition to any water garden.

Originally from East Asia, Nishikigoi was domesticated and can adapt to diverse climates. They have the same ancestor as carp.

Some varieties resemble Goldfish in body shape and color and have prominent barbels on their lips. However, they are distinct from other species.

Nishikigoi is temperate freshwater fish that can live up to 70 years. Their optimal water temperature is 70degF (20degC). Koi ponds should be deep enough to keep water temperatures stable.

Chagoi Koi Fish

Chagoi Koi Fish are large, nonmetallic Koi fish that grow to over forty inches long. They have thick bodies and wide heads. They are known for being easy to handle and can be trained to eat from the hand.

They also have a good growth rate, and their genetics are closer to common carp than other varieties.

Chagoi Koi Fish have a distinctive fukurin pattern on their scales. This pattern is black and creates a fishnet-like pattern over the brown color.

Some varieties of Chagoi are scaleless or have no fukurin at all. Either way, they are still beautiful.

When choosing a koi to purchase, you should look for one that is lively and looks healthy. If possible, try to avoid those with visible injuries.

Chagoi are very sensitive to pH levels and water temperature, so it is important to check these factors before buying.

The Asagi Koi is an ancient variety of koi that served as the basis for several later koi breeds. These koi have blue and white striped scale patterns on their dorsal fin and touches of red on their body.

When purchasing a koi, look for a consistent pattern across its body. Some Koi will have yellow patterns on their body, but others will have black bodies with white pattern.

A pattern that covers the entire body is an indication of a rare variety. In addition to a patterned body, Chagoi Koi Fish come in scaleless forms called Doitsu and Kikosui.

Koi breeders chose the biggest and friendliest fish from each generation. This resulted in most of the fish being tame. The color of the fish also changed from their wild counterparts.

Eventually, the tame ones were kept as pets and sometimes even sold. The tamed Chagoi became popular with newcomers to the hobby.
