There are various species for this kind of fish. First is the Magoi Koi, one of the first of all black mutations that can grow very long. When viewed from above, they may look black, but in reality their color is deep bronze. The Magoi blood is being reintroduced to other species in order to speed up and maximize their growth potential (due to their great possibilities when it comes to size).

The Karasu Koi (which means “crow” in Japanese) is another one of those very old species. It is characterized by its black fins and body. They also have orange or white bellies.

The Matsukawabake is characterized by its areas or white on its body. This one has the ability to change color. Due to their diet and environment, their color will change from duller or brighter shade of color.

It will return to its original color and pattern once there’s a change in condition.

The Kumonryu is considered as the most popular of the species. It first debuted in the 1980’s. “Kumonryu” means “dragon fish” in Japanese. It’s been called as such because its body is reminiscent of those of the dragons represented in ancient paintings.
