2. What is the scale loss of map fishMap fish is a kind of fish with strong ornamental value. If scale loss occurs, it is likely to be caused by injury. They are fierce in character and often conflict because of competing for territory. Once fighting, it is easy to get hurt.
It is also possible that the water quality is too poor. Map fish do not have very high requirements for water quality, but they pollute the water quality seriously. When there are too many bacteria in the water, they will fall off scales.
It is also possible that they are frightened. Although they are larger, they are less daring. If there is a loud noise around or someone suddenly appears around the fish tank, they will be frightened.
