It usually takes about seven days to cure fish enteritis, and it takes about ten days for serious cases. There are many reasons for fish enteritis, which may be fed deteriorated food, irregular feeding at ordinary times, or too much food fed at one time. Therefore, in the daily feeding process, we must pay attention to regular and quantitative feeding of food, and it is best for fish to finish eating within 3-5 minutes after each feeding.

1. Stop eating and isolate: After a fish gets enteritis, it should be stopped first. Sick fish often have a bad appetite and don't eat it after feeding. However, if these foods become residual bait, they will continue to pollute the water body, which is very unfavorable to the health of fish. In order to prevent the disease from spreading or bullying, the sick fish should be isolated and raised in a separate fish tank.

2, the old three types: For enteritis, the old three types should be used for treatment first. The so-called old three things are changing water, heating up and adding salt. Changing water should be changed every other day, so as to maintain water quality as soon as possible. Heating up can promote metabolism, but it should not rise too high at one time, preferably 2 ℃ every day, and the concentration of salt should also be paid attention to, which is usually five thousandths.

3. Medicinal soaking: If the illness is serious and the old three can't achieve the therapeutic effect, it is necessary to take a medicated bath. The commonly used drug is furazolidone, and 4-6 tablets should be added for every 100 liters of water. After three days, if the feces are normal, you can stop taking the drug and change the water.
