For mild diseases, measures should be taken in time. First check whether the fish has floating head and stop eating. If there is no floating head and no food, you can take the first use of sprinkling the topical medicine and then feeding the medicine. Otherwise, you must first take oxygen or water quality improvement measures before the floating head disappears before you can splash drugs. For severe diseases, fish and shrimps generally float on their heads and are accompanied by a large number of deaths. At this time, it is not possible to simply decide on the use of drugs. The cause of death should first be ascertained and measures such as water exchange, aeration, or water treatment should be taken to alleviate the disease. With improved conditions (decreased number of dead fish), disinfectants and insecticides can be spilled. If the disease is severe enough to directly sprinkling drugs with relatively high toxicity, such as disinfectants and insecticides, it will only increase the number of deaths and lead to greater losses.
