Black Koi – A Variety to Behold

The Black Koi fish is one of many varieties that have been bred over the years. This variety like most of the others, are set apart by their color. First bred by the Japanese, these fish can live for an incredible life span. Some have been said to live for 200 hundred years. The more normal life span is about 25 to 35 years – still a very long life for a fish. As breeding has continued these fish now appear in ponds all over the world displaying brilliant colors and admired by all. When spawning, 1,000 eggs can be laid. The baby Koi known as Fry will start to emerge in about 4 – 7 weeks depending on the temperature of the water. Their color will come somewhat later in about 3 – 12 weeks.

When Koi were first bred by the Japanese from carp mutations they only came in one or two colors.  Now after continued breeding more and more color varieties and patterns have appeared. In the future who knows what might emerge. One thing is for sure. The possibilities are endless.

The Black Koi can grow to 36 inches in length. For this reason, like most Koi they need to be kept in large outdoor ponds. The Magoi species is one of the first all black varieties. They are actually bronze in color but look black when viewed from above. Because this species can grow so large, they are being used to breed other varieties with faster and larger growth potential.

There is more than one variety of Black Koi. The Karasu species is another extremely old variety of Koi. Karasu means “crow” in Japanese and is characterized by black fins and a black body.

The Kumonryu is probably the most popular variety of the Black Koi species. The name means “dragon fish.”  Early breeders thought these fish reminded them of dragons that were depicted in ancient paintings ascending through white clouds in the sky.

Some Koi have the interesting tendency to change colors. The color change is induced by changes in their environment and diet. With changes in the seasons and the change in the temperature of the water, the color of some Koi can change completely. They can be seen turning completely black or white. What’s even more amazing is the fact that they will revert back completely to their original color when the conditions change.

It’s no wonder that having a Koi pond is one of the most rewarding hobbies around. Imagine having fish that will actually change color right before your eyes. Taken care of properly, Koi fish can be enjoyed for many years. It may take a little time and effort to maintain your Koi pond, but the rewards and enjoyment you’ll get is well worth it. Take the time to learn how to take the best care of your Koi fish. They will reward with years of pleasure and enjoyment.
