What should I do if a Tancho Sanke koi shows symptoms of illness?

The Tancho Sanke koi has a body made up of three colors of markings. White is the base color; there are black markings on the body, and the black markings must not extend over the head, making the body look like a Shiro Bekko; a single red spot on top of the head makes it a "Tancho Sanke."

If red appears anywhere other than the head, then it cannot be called a Tancho Sanke koi. In other words, to be a Tancho Sanke, in addition to the color markings already present on the body, what matters more is that only a single red spot on top of the head qualifies it as a "Tancho."

1. First, look at the distance between its eyes. Whether the distance between the two eyes is wide enough; koi whose eyes are set relatively far apart will usually grow to a larger size; the base of the pectoral fins all the way to the tip of the snout, that is, whether the length of the head is long enough; then check whether the distance between the eyes and the mouth is too short.

2. The mouth should be somewhat thick; thin-mouthedkoiare very difficult to raise into large fish.

3. Whether the cheeks are evenly full, and the top of the head must be full; koi with a flat top of the head are less ideal.

4. Pectoral fins that are too small, too pointed, or triangular are not considered good. The body shape from the pectoral fins to the caudal peduncle must be very smooth, with no sudden bulges or hollows.

5. The caudal peduncle should be thick and strong; from the caudal peduncle one can also tell whether a fish's build and development are good.

6. When viewed from above, besides having an appropriate width, the fish's body must also have an appropriate side height, and the highest point should be slightly in front of the dorsal fin. If the highest point of the side height is in the middle of the dorsal fin, making it look hunchbacked, it is not up to standard.
