13 Different Types of Koi Fish

A collage of different types of koi.

Koi fish are more commonly known as Nishikigoi or jinli, which literally means ‘brocaded carp.’ They are colored varieties of koi species Cyprinus rubrofuscus. Koi fish are colorful fish which are commonly seen in outdoor water gardens and koi ponds.

Numerous varieties of koi fish have been identified by the Japanese. These koi fish varieties are distinguished on the basis of coloration, scales, and patterns. Koi fish are majorly found in white, red, black, blue, yellow, and cream colors.

It is believed that koi fish originated in China and were later used by the Japanese as a food source. It was in the mid-1800s that the Japanese started breeding these fish for their aesthetic appeal.

Koi fish are incredibly smart. They can be trained to eat from out of your mouth and hand. They are omnivores that feed on pond plants. Koi fish also live for a very long time. Their average lifespan is about 50 years, and they can grow to be 36 inches long.

Different Types of Koi Fish – Names and Pictures

Out of more than 100 types of koi fish, there are only a few that are quite popular.

Each type has a different pattern and color that distinguishes it from other types of koi fish. The most common types of koi fish have been listed down for you.

1. KohakuWhite and orange Kohaku koi fish

Kohaku is considered the king of all koi fish. This is the first variety of koi fish that developed with two colors. Its simple beauty and majestic look make it an automatic favorite for any aquarium or koi pond.

Kohaku Koi Fish Colors

The Kohaku koi fish has a body that is a stunning white color (shiroji), with red blotches adding a bit of color to its otherwise uniform look. Most Kohaku fish have a yellowish nose. The red markings, that are traditionally called hi, are of two types.

The first type is red that has a purple tint to it. These markings appear quite thick, but as the fish ages, the markings fade, resulting in the absence of crisp margins. This color is quite easy to maintain, so Kohaku fish with this type of marking is usually the best choice for inexperienced koi fish owners.

The second type of marking is more popular than the first one. It is orange-red in color but is a lot more difficult to maintain. These markings have a crisp margin that is quite visible between the white and red.

Kohaku fish with orange-red markings are a preferred choice of people who are experienced with taking care of koi fish.

Pattern of Markings

The markings on the body of Kohaku fish make them stand out. Most Kohaku has a red-colored mark on their head that is usually separate from the markings on the rest of their body.

However, sometimes, the markings on the body may extend to the head. These Kohaku are known as the bongiri. Kohaku with no markings on their heads is known as the boze.

No matter what color or pattern a Kohaku comes in, this type of koi is a stunning addition to any aquarium or a pond.

2. Taisho SankeWhite, orange, and black-colored Taisho Sanke koi fish

Taisho Sanke is also known as the Taisho Sanshoku or simply Sanke. 

Taisho Snake Koi Fish Colors

Sanshoku means three colors. This name corresponds to the presence of three colors on the body of this type of koi – white, red, and black.

It is quite similar to the Kohaku koi. Just like Kohaku, it has a white body (shiroji) with red-colored markings (hi). The only difference is the presence of black markings (Sumi markings) on its body. Taisho Sanke is among the ‘Big Three’ in the world of koi fish.

Pattern of Markings

The head of a Sanke usually comprises of two colors, which are white and red, and is devoid of any Sumi markings. Another difference between Sanke and Kohaku is that the red markings begin from the top of the head, so the face is generally clear.

The pectoral fins are white at the base with a few Sumi markings.

3. ShowaShowa koi fish with black, white, and orange colors

Showa is also known as Showa Sanshoku or Showa Sanke.

Showa Koi Fish Colors

As mentioned earlier, sanshoku means three colors. Showa gets its name due to the presence of white, red, and black colors on its body.

Showa is quite similar to Sanke. However, the main difference that sets the two types of koi fish apart is the Karasu (black-colored body) of the Showa. Showa has white and red-colored markings over a mostly black-colored body or base.

Pattern of Markings

Unlike Sanke, Showa koi fish have a black pattern that runs throughout their bodies. Sanke koi fish, on the other hand, only have a black pattern on the upper half of their bodies. Moreover, Showa have black patterns on their heads, which is not the case with Sanke.

The white, red, and black-colored markings are distributed evenly throughout the body, with crisp and clean margins between each color.

4. TanchoRed spot on the head of Tancho koi fish

The Tancho koi fish is named after the national bird of Japan, the Tancho Crane, which has a prominent red spot on its head. Tancho is simple and sleek and is known for the trademark pigmentation (a red spot) on its head.

The Red Spot

Tancho Kohaku is the most picturesque Tancho. It is snow-white in color and has a crimson red-colored spot on its head. This spot is traditionally round in shape, but it can be found in other symmetrical shapes as well.

To fall under the Tancho umbrella, the spot on the head should be symmetrical, whether it is circular, oval, heart-shaped, or diamond-shaped.

The spot should be a dominating size and should not be speckled. The defining characteristic of a Tancho koi fish is a single, clear, prominent, red-colored spot.

Other commonly found Tancho varieties include Tancho Showa and Tancho Sanke.

5. UtsuriUtsuri koi fish with a black body and red pattern

Utsuri is not just a single type of koi fish. It is the name of a category, Utsurimono, that includes three types of Utsuri koi fish; Shiro Utsuri, Ki Utsuri, and Hi Utsuri. 

Utsurimono means reflection. The koi fish that fall under in the Utsuri category have a black-colored body (Karasu) with red (hi), white (shiroji), or yellow (ki) markings.

The category has been named Utsurimono to indicate the overlaying red, white, or yellow patterns that suggest the reflection of the color on the body of koi fish.

Pattern of Markings

The sumi pattern on the head of an Utsuri koi fish is similar to that of Showa, that is, a Sumi mark that divides the face. The Sumi pattern that is present on the body is also similar to that of Showa. A large, prominent, reflective Sumi pattern is present on the entire body.

The Sumi is wrapped around the body just below the lateral line in the Utsuri koi fish. These markings extend to the tail from the nose and are balanced throughout the length of the body as well as on both sides of the dorsal line.

6. BekkoBekko koi fish with a white base and black markings

The literal meaning of Bekko is ‘tortoise shell.’ Bekko and Utsuri are often confused.

However, the major feature that helps in distinguishing the two is that Utsuri has a black base with white, red, or yellow-colored markings whereas Bekko has a white, red, or yellow-colored base with Sumi (black-colored) markings.

The head of a Bekko will always be clear of any Sumi markings.

Bekko Koi Fish Colors

The known variants of Bekko include Shiro Bekko (white body), Aka Bekko (Red body), and Ki Bekko (yellow body). The most common of all these variants is the Shiro Bekko.

Pattern of Markings

The characteristic feature of a Bekko koi fish is that it will have no markings (black-colored Sumi markings) on the head. Sumi markings will be spread throughout the white, yellow, or red-colored body.

7. AsagiAsagi koi fish with a net-like pattern

Asagi koi fish are strikingly beautiful creatures. They have a blue-colored, net-like pattern on the top of their bodies with red-orange coloration on the belly, fins, gill plates, and the body. As the Asagi koi fish ages, the red coloration (hi) spreads upwards from the bottom.

Pattern of Markings

The Asagi koi fish whose bodies are more red than usual is known as the Hi Asagi. Another type of Asagi koi that is quite popular is the Taki Asagi.

It has the typical blue-colored net pattern and red coloration along with an additional white-colored line of scales that runs between the red and blue pigmented areas of the fish’s body.

The head of an Asagi is usually clear, without any markings. The color of the head is usually white or pale blue.

8. ShusuiShusui koi

Shusui is a version of Asagi koi, but the difference is that Shusui is the Doitsu or scale-less version of Asagi. Due to the absence of scales on the top of the body, there is no blue-colored net-like pattern. The scales that are present form a single row along the dorsal line of the body.

Pattern of Markings

The color of a Shusui’s head is pale blue or white and does not have any markings or spots. The presence of red-colored, extended cheeks is a common occurrence in Shusui koi fish.

There are no specifications regarding the markings on the body except for the presence of a single row of scales running neatly and uniformly along the length of the back.

9. Koromo

Koromo or Goromo is one of the most stunning types of koi fish. It is a hybrid of a Kohaku and an Asagi ki fish.

Koromo Koi Fish Colors

It has the characteristic colors of a Kohaku (white and red) and the characteristic net pattern of the Asagi koi fish.

Pattern of Markings

The body of a Goromo koi fish is white-colored with a red-orange pattern on the body just like a Kohaku koi fish.

What makes it different from the Kohaku is the blue-colored, net-like pattern of the scales on each of the red-colored scaly patches that are present on the body of a Goromo koi fish.

There are three different variants of the Goromo koi fish, which are:

  • Aigoromo: It has an indigo-blue colored edge to the scales (known as the ai) within the red-colored patterns (hi).
  • Sumigoromo: It has a black-colored edge to the scales (sumi) within the red-colored pattern (hi).
  • Budogoromo: It has an overlaid red-colored (hi) pattern with a black-colored (sumi) pattern, which gives its hi pattern a grape-like (called budo) appearance.

10. Goshiki

Goshiki means five colors. This type of koi fish has a solid, white-colored body with an Asagi-like black-blue, net pattern spread throughout the length of its body. It is the result of breeding between Asagi and Kohaku koi fish.

There is a red-colored (hi) plate that comes from the Kohaku, over the net-like pattern that comes from the Asagi. It is named Goshiki because of the presence of various colors which are: white (of the base), red-orange (of the hi-plate), and blue and black (of the net-like pattern).

As the Goshiki ages, the red hi plate become so thick and dense that it appears as an external sticker over the body of the koi fish.

The net-like pattern also disappears, and only the thick red-colored plate remains throughout the body. If the koi has been taken care of the right way and the colors develop correctly, a Goshiki koi fish is a stunning sight to see!

11. KawarimonoKoi pond with Kawarimono koi fish

Kawarimono or Kawarigoi is a family of koi fish that comprises of fast-growing, large-sized koi fish. The most prominent types of koi fish in this category are:

  • Hajiro: It is a koi fish with a black body (sumi) with white-colored (shiroji) tips on its fins and tail.
  • Hageshiro: This koi fish is quite similar to Hajiro, but has a white-colored face and head instead of white-colored tips on its fins and tail.
  • Kumonryu: Also known as the dragon fish, it is a koi fish that has a Sumi Doitsu body with white-colored, swirling markings on its entire body and head. The pattern is not fixed. It changes with the season.
  • Ochiba Shigure: The name means fallen leaves. It is so named because it has a Kohaku-like pattern that overlays a blue-gray (sora) body. This pattern resembles fallen autumn leaves over water.

  • Benigoi (dark-red)

13. Hikari Moyo

While the single-colored Ogon, Kin, and Matsuba fall in the category of Hikari Muji, all the Hikari (metallic) koi fish that have two or more colors fall under the umbrella of Hikari Moyo.

Numerous types of koi fish that fall under this class are a result of breeding between different Hikari Mono koi fish.

Hikari Moyo is a breathtakingly beautiful family of koi fish. A combination of shimmering skin with striking patterns and coloring makes Hikari Moyo koi fish a splendid sight to look at!
