Black is one color that is never out of fashion. Black is classy, black is smart, black is evergreen, black is dignified … black is black. From cars to apparels to pets, the color black has a kingdom of its own. And the world of Koi is no exception. Among Koi lovers, be they professional breeders or hobbyists or simply Koi enthusiasts, black Koi has done the imagination of many. There are many who specifically look for black Koi. And why not, a black Koi swimming gracefully along the other bright colored ones is a sight to relish. Apart from its color, two other reasons that have added to the popularity of the black Koi are its larger size and its ability to change color. The color change occurs due to a change in water temperature (seasonal) or due to a change in their food.
And 'logic' can well be the third reason. A black Koi is less visible to predators against the dark background of the pond. So the color is an insurance policy, is not it? Feel like LOL? Well, it was meant to be a joke!
It is important to note here that there is no difference between the colored Koi and the black Koi. They are just the same. 'Black' is just another color in which Koi is available. You can get an 'all black' Koi or a black with some colorful marks. Some Koi varieties have been classified into various categories based on their black color.
These are listed below.
– Karasu – This can be called an all black Koi as the parts of its body that are visible to the spectators' eyes are black. However, the belly of this fish can be white or orange. Since the upper body and fins are completely black, this Koi is also called 'crow Koi'. Also, Karasu literally means crow in Japanese.
– Matsukawabake – This Koi is a mixture of black and white. It can turn completely black (or white) in certain circumstances, due to seasonal color change.
– Showa Sanshoku / Sanke – It's a black Koi with red and white markings. But sometimes the white on the body increases so much that it can get confused with Taisho Sanke, which is a white-skinned Koi.
– Utsurimono – This black Koi has a red, white or yellow marking.
– Kumonryu – It is a black doitsu scaled fish with curling white markings. It is also known as the dragon fish because of the resemblance it bears to the pictures of dragons depicted in oriental paintings. These are famous for changing color with season.
In addition to these there are some varieties that are not actually black but appear to be black, when viewed from the top, due to their very dark tones.
These include the following varieties.
– Tsumi Goromo – This is a type of Koromo Koi. It has a very dark burgundy high overlay, patterned in a manner that creates the effect of a grape bunch. Due to this extremely dark color it appears to be almost black.
– Magoi – This fish has deep bronze scales and thus appears to be black. Some do not consider this to be a true Koi. As they are free from the stagnating effects of breeding for color mutations, they can grow really huge.
Due to this quality their blood is being reintroduced into some Go Sanke bloodlines to maximize the growth potential.
Could you ever imagine that 'black' could be so 'colorful'? In the magical world of Koi, colors are like refraction from a prism; a slight change and you have a different set of myriad colors!
