I. Symptoms and pathological changes

At the beginning of the disease, pectoral fin, dorsal fin, caudal fin and skin on the body surface were scattered in white spots. Although the sick fish are fed as usual, they often gather in the corner of the fish tank and rub against each other. After a few days, the whole body is covered with white spots, and sick fish often float on the water in a dull state. The serious whole body seems to be covered with white powder, which mostly occurs in spring, autumn and rainy season, especially under the tail of live bait due to lack of light and low temperature. The disease spreads quickly. If not treated in time, it will cause secondary infection and bacterial infection of water mold. In severe cases, this drug will be ineffective and a large number of people will die. Need early treatment.
