Koi fish come in a wide range of colors and patterns, each with unique characteristics. These ornamental fish have been selectively bred for centuries, resulting in numerous varieties highly valued by collectors and enthusiasts. Here are some of the most popular koi varieties and what makes them special.
Kohaku
One of the most recognizable koi varieties, Kohaku features a striking red pattern over a pure white base. Simplicity is key with Kohaku—well-defined, crisp red markings (hi) and a clean white body (shiro) are the most desirable traits.
Showa
Showa koi exhibit a dramatic mix of black (sumi), white (shiro), and red (hi) patterns. Unlike the similar-looking Sanke variety, Showa koi have dominant black coloration that extends across the body. The interplay of these three colors creates a powerful and dynamic appearance.
Taisho Sanke
Often referred to simply as “Sanke,” this variety features a white base with red and black markings. Unlike Showa, the black patches on Sanke koi are more subtle and do not cover the head. A well-balanced pattern with bright, defined colors is highly prized.
Asagi
Asagi koi have a mesmerizing blue net-like pattern on their scales, complemented by red or orange markings on the belly and fins. Their unique coloration gives them an elegant, understated beauty, making them a favorite among collectors who appreciate classic koi varieties.
Ogon
Unlike patterned koi, Ogon are solid-colored metallic koi that shine brilliantly under sunlight. Common colors include platinum (pure white), yamabuki (golden yellow), and orange. Their shimmering scales and uniform appearance make them highly sought after for their striking simplicity.
Bekko
Bekko koi are characterized by black markings (sumi) over a solid white, red, or yellow base. They are often mistaken for Sanke, but unlike Sanke, Bekko lack red markings. Their clean and balanced pattern makes them an attractive choice for koi enthusiasts.
Shusui
A variation of Asagi, Shusui koi have a blue-gray body with a distinctive row of dark scales along the dorsal line. They often feature red or orange on the sides, creating a striking contrast. Shusui are among the few koi varieties with a semi-scaled (doitsu) appearance.
Conclusion
Each koi variety has its own unique appeal, whether it’s the bold contrast of Showa, the simplicity of Kohaku, or the metallic brilliance of Ogon. Understanding these differences helps koi keepers appreciate the beauty and history behind each fish. Choosing a koi variety depends on personal preference, but regardless of the type, proper care and a healthy environment will allow these stunning fish to flourish.
