Black koi fish are koi fish that have the black koi pattern. Many people choose the black koi over other koi fish.

Many koi ponds across the globe have black koi fish just because koi are beautiful fish that live for a very long time.

Koi fish were initially bred from carp in Japan. Koi come in many colors, not only black. Black koi fish particularly were bred from carp fish that had one or two colors. Thanks to the dedication and determination of Japanese koi breeders, koi breeders from around the world, as well as koi lovers, are able to take pleasure in a wonderful colorful array of koi fish today.

The male and female koi fish have characteristics that separate them from each other. For instance, the male koi fish have concave anal areas and they are identified by a breeding spot on their heads. Soon after spawning, the female koi is capable of laying as much as a thousand eggs. The fry (baby koi) hatch anywhere from four to seven days, depending on the temperature of the pond. Koi spawning as well as fry hatching may happen very fast, but it usually takes 3 to 12 weeks for the fry to show their diverse colors.

Another black koi is the Karasu koi, also referred to as the crow koi. The body of this koi is black and its fins can be black also. The Karasu koi's belly may also be white or orange in color.

Are you aware that almost all koi change their colors and this is in reaction to the environment, especially their diet? Healthy koi fish usually have vivid colors. One specific koi, the Matsukawabake koi, is popular for its changing colors. Although it is considered as a black koi, the Matsukawabake koi can change its color pattern when the water temperatures or foods change. This certain koi can appear completely black on one day and completely white on the following day. This black koi typically goes back to its original colors when its environment and diet go back to normal or original condition.

Among the different kinds of black koi, the Kumonryu koi or commonly known as dragonfish koi, appear to be the favorite black koi of many koi lovers.
