What is the difference between Yotsushiro koi and Tancho koi

You may have seen such a koi: while you are happily admiring the colorful koi in the pond, suddenly a black-and-white koi swims into your view. It looks like a Karasugoi, with a jet-black body, but its head, left and right pectoral fins, and tail fin are white. Swimming gracefully to and fro, it calms your eyes that have been lost among the jumble of colors, and your mood relaxes along with it. This is the Yotsushiro koi, whose English name is Yotsushiro.

The Yotsushiro koi belongs to the Karasugoi among the variant koi. The Karasugoi was derived from the Konjo Asagi koi; the whole body of the fish is black, dignified and elegant, and it has a certain ornamental value. Based on where white markings appear on the fish body, it is further divided into the Hirehakko koi, the Kamihakko koi, and the Yotsushiro koi.

 

Koi varietiesAmong them, relatively speaking, Hakushu gives people an impression of simplicity and fortitude, and its contrast of black and white seems to have a quiet, antique flavor. The Yotsushiro koi, by contrast, has clearly distinct black and white. Because the pairing of black and white is forever the most fashionable element, the Yotsushiro koi is more concise and stylish to appreciate; black and white contrast with each other and are distinct, unlike the pure black Karasugoi, which looks more profound.

The two "sibling brothers" of the Yotsushiro koi, the Hirehakko koi and the Kamihakko koi, are also very easy to distinguish from each other. The Hirehakko koi shows only a little white at the tips of the pectoral fins, while the Kamihakko koi shows white at the edges of the pectoral fins, the tip of the nose, and the top of the head. From its name, one can see that the Yotsushiro koi has four parts that appear white, namely the head, the left and right pectoral fins, and the tail fin appearing white.
