The Black Koi Fish
Black koi fish are koi fish that bear the black koi pattern. A lot of people favor the black koi over other koi fish. In general, koi fish, which come from the carp family, are known to live up to 35 years, even though there are records that carp can live for over 200 hundred years! A lot of koi ponds around the world have black koi fish just because koi are beautiful fish that live for a long time.
Koi fish were originally bred from carp in Japan. Koi come in many colors, not just black. Black koi fish specifically were bred from carp fish that had a couple of colors. Thanks to the commitment and determination of Japanese koi breeders, koi breeders from around the world, as well as koi enthusiasts, are able to enjoy a wonderful colorful array of koi fish today.
The male and female koi fish have features that distinguish them from each other. For example, the male koi fish have concave anal parts and they are identified by a breeding spot on their heads. After spawning, the female koi is capable of laying as many as a thousand eggs. The fry (baby koi) hatch anywhere from four to seven days, depending on the temperature of the pond. Koi spawning and fry hatching may happen very quickly, but it normally takes 3 to 12 weeks for the fry to reveal their diverse colors.
Like any other koi fish, black koi have to be kept in ponds that are large enough since koi fish tend to grow up to three feet long. The Magoi koi, which is a popular black koi, is known to grow large very quickly. The Magoi koi may look like bronze if it's observed from all directions besides from the top. Many koi breeders are using this particular black koi for breeding with other koi in order to create large koi in different color patterns. Another black koi is the Karasu koi, also known as the crow koi. The body of this koi is black and its fins are also black. The Karasu koi's belly can also be white or orange in colour.
Are you aware that almost all koi change their colors and this is in response to the environment, particularly their diet? Healthy koi fish usually have vibrant colors. One particular koi, the Matsukawabake koi, is well known for its shifting colors. Although it is considered as a black koi, the Matsukawabake koi can change its color pattern when the water temperatures and foods change. This particular koi can appear completely black on one day and completely white the next. This black koi usually goes back to its initial colors when its environment and food go back to normal or original condition.
Among the different varieties of black koi, the Kumonryu koi or dragonfish koi, appear to be the favorite black koi of many koi enthusiasts. This black koi is tagged "dragonfish" because it resembles an ancient dragon in the pictures. This black koi has a tendency to go through color changes when the seasons change.
Koi ponds from all over the world will have koi fish in a wide variety of color patterns. Koi fish are a wonderful addition to any pond. With their changing colors, they can provide unlimited hours of entertainment for anybody. Why, even the black koi fish alone are unique enough in their color changes!
