1. Suspend feeding: After a fish gets saprolegniasis, the first thing to do is to suspend feeding, because at this time its appetite will be affected by injury, it does not eat much, and the food it feeds will become residual bait, which will lead to deterioration of water quality. Do not worry about the fish will starve to death, this kind of animal hunger-resistant strong, cured after feeding is not too late.
2. Change water regularly: In order to improve the condition of the water body, it is necessary to change water regularly for the sick fish. Change water every other day should be carried out once, each time do not change too much, of course, if the drug has been used, the amount of water or to a larger number, while changing the water will continue to add medicine.
3. Appropriate warming: Saprolegniasis is easy to suffer from when the temperature is low. If you want to treat it, warming is also necessary. Raising the temperature can stimulate the resistance of the fish, but also accelerate the metabolism, so that it will discharge harmful substances, which is very helpful for its recovery.
