types of koi fish

Commonly called jinli or nishikigoi and belonging to the Cyprinus rubrofuscus species, the many types of koi fish or brocaded carp are colorful ornamental fish that are usually seen in koi ponds and outdoor water features.

Developed mainly for their colors, beauty and vivid patterns, koi varieties can be differentiated on basis of their patterns, coloration and scales and are usually seen in colors like red, black, white, yellow, blue and cream.

Believed to have their origins in China, koi fish became a popular source of food for the Japanese and were later bred for their ornamental and aesthetic appeal. Koi are smart and hardy fish.

They are omnivorous and eat pond plants. Koi fish can grow up to 36 inches in length, have long lifespans and can live up to 50 years.

Over 100 different types of koi varieties exist; however, only a few of them are very popular. These vibrant and attractive fish can add life and color to any pond or aquarium.

12 Types of Koi Fish

Each koi variety is distinguished by its unique pattern and colors and if you want to know all about the different varieties of koi, read on.

Kohaku Koi Fish

kohaku koi is considered to be the king of all koi fish breeds

Kohaku, meaning “amber” in Japanese is regarded as the king of all koi fish varieties. This variety is popular for its simplistic, but majestic beauty.

Bred around the 1890s, the Kohaku koi has a beautiful white-colored or “shiroji” body with patches or red or hi, which can vary between dark red and orangish-red.

The hi pattern further distinguishes these koi fish types. For instance, the variety with the hi in a zigzag pattern is called Inazuma or “lightning strike” Kohaku.

The Kohaku koi have a yellow-colored nose and distinctive markings on the body, making them stand out. The majority of the Kohaku koi fish have a red-colored mark on the head, which is different from that on the rest of the body.

The body markings may sometimes however extend to the head and these Kohaku koi types are known as “bongiri.”

The fish without the red spot on the head is called “bozu.” Kohaku koi are indeed stunning fish and it’s no wonder, the saying goes, “appreciation of koi begins and ends with the Kohaku.”

There are different varieties of the Kohaku koi including Gin Rin Kohaku, Tancho Kohaku, Maruten Kohaku and Doitsu Kohaku.

Showa Sanshoku Koi Fish

some types of koi, like showa sanshoku koi, have black pattern on their body

Also called Showa Sanke or simply Showa, the Showa Sanshoku koi are similar to the Sanke koi; however, the primary difference is that the Showa koi fish types have a black body (karasu) with white (shiroji) and red (hi) markings.

The Showa Sanshoku has a black-colored pattern running throughout their bodies and heads. The black, red and white-colored markings are uniformly distributed through the body of the Showa Sanshoku koi with clean and crisp margins between each of the colors.

Meaning “autumn green”, Shusui koi fish were developed in 1910 by breeding the German Mirror Carp with Asagi. The Shusui koi types are a scale-less or Doitsu version of the Asagi.
