The Black Koi Fish
Black koi fish are koi fish that have the black koi pattern. Many people prefer the black koi compared to other koi fish. Overall, koi fish, which originate from the carp family, are known to live as much as 35 years, although there are reports that carp can live for more than 200 hundred years! A lot of koi ponds around the world have black koi fish just because koi are magnificent fish that live for a long time.
Koi fish were originally bred from carp in Japan. Koi are available in several colors, not just black. Black koi fish specifically were bred from carp fish that had one or two colors. Thanks to the dedication and patience of Japanese koi breeders, koi breeders from all over the world, as well as koi enthusiasts, are able to take pleasure in an amazing colorful array of koi fish today.
The male and female koi fish have characteristics that distinguish them from each other. For instance, the male koi fish have concave anal parts and they are characterized by a breeding spot on their heads. 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 reveal their diverse colors.
Like any other koi fish, black koi have to be placed in ponds that are large enough since koi fish have a tendency to grow up to three feet long. The Magoi koi, which is a well known black koi, is known to grow large very quickly. The Magoi koi may appear bronze if it's viewed from all directions other than from the top. Many koi breeders are making use of 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 called the crow koi. The body of this koi is black and its fins are also black. The Karasu koi's belly may also be white or orange in colour.
Did you know 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 popular for its shifting colors. Although it is regarded 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 entirely white on the following day. This black koi usually goes back to its initial colors when its environment and diet go back to normal or original state.
Among the different kinds of black koi, the Kumonryu koi or commonly known as dragonfish koi, appear to be the favorite black koi of most koi enthusiasts. This black koi is called "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 an excellent addition to any pond. With their changing colors, they can provide unlimited hours of entertainment for everybody. Why, even the black koi fish alone are diverse enough in their color changes!
