1. how to treat

fish hemorrhagic disease? After the fish suffers from hemorrhagic disease, it can be soaked in salt water for 10-15 minutes at a concentration of about 2-3%, once every other day until it recovers. The furacilin medicated bath can also be used, the concentration is between 0.01 and 0.02%, and the soaking time and frequency are unchanged. Or after fishing out the fish, dip a cotton ball in mercurochrome and smear it on the affected area once a day, which can also make it recover gradually.

Bacterial bleeding: Bacterial bleeding is usually caused by the deterioration of water quality. If you want to treat it, you need to change the water regularly to ensure that the water is clean and hygienic. The water is usually changed once a week, a quarter or a fifth at a time, and too much can irritate the fish and even cause stress reactions.

2. Injuries caused by fighting: When fish are mixed in a fish tank, it is not necessarily safe. They may fight. Once they fight, some fish will be injured and bleed at this time. After discovering this situation, it is necessary to isolate the fighting fish as soon as possible to prevent them from fighting again, and to sterilize the injured fish.

3. Environmental stimulation: The fluctuation of water quality and water temperature will stimulate the fish to a certain extent. Under this stimulation, the fish will also have bleeding symptoms. Therefore, attention should be paid to maintaining water quality at ordinary times, the temperature before and after water change should not be too high, and a good nitrification system should be established in the water to prevent harmful substances such as ammonia nitrogen from exceeding the standard.
