Goldfish's scales are raised because of squamous disease. It is usually due to poor water quality or viral infection that causes goldfish to become sick. Therefore, when goldfish suffer from scaly disease, the owner must first change the water in the fish tank, raise the water temperature to about 30 degrees, and add an appropriate amount of coarse salt. For disinfection and sterilization, if there is no effect, potassium permanganate solution should be used for treatment.

Tip:

When raising fish, the owner must regularly change the water in the fish tank, and the stocking density should not be too high. Too high a stocking density will cause the water quality to deteriorate rapidly, and the unfinished food of the fish must be removed after each feeding. Residues and excrement are cleaned up to prevent the water quality from deteriorating and affecting the fish.
