1. Cause: When koi live in seriously polluted water, they will lose their scales. This is because the water environment is not clean, which leads to a large number of harmful bacteria breeding and infection of Koi.
2. Treatment method: In this case, the diseased fish should be fished out in time, put into the isolation tank, and disinfected with salt. It is also necessary to disinfect the original tank and replace the water in the original tank so that the bacteria in the tank will not infect the healthy koi.
breeding density 1. Reason: For general family breeding, if the fish tank is too small or the number of breeding is too large, it will lead to excessive breeding density. When the breeding density is high, they will collide with each other or grab food, which will lead to the phenomenon of Koi scale loss.
2. Treatment method: In this case, a large fish tank should be replaced, or they should be raised in separate tanks to prevent the lack of space for their growth caused by excessive feeding density. Also add 1% coarse salt to the water to sterilize.
1, reason: Koi's courage is relatively small, when they are frightened, there will be a series of abnormal reactions, for example, scales may fall off.
2. Treatment method: In this case, oxygen can be exploded first. Exploding oxygen can improve their metabolic capacity, but do not feed them during this period. Because the frightened koi will have a reaction of loss of appetite, feeding will leave food residues in the fish tank. After they recover a little, they can rest slowly.
