You also need to add about 0.6 teaspoons salt per gallon. Later, you need to change the water after about 10 days and lower the temperature over several days. See the result in 21 days to find out that your fish completely get back to normal or not.

The symptoms are the fins edges turn white and slowly rot away.  The treatment can begin by taking the infected fish out of the tank and cleaning the tank, all the accessories, and also the gravels. After cleaning them, you change the water with around pH 7-8 and ammonia, nitrates, and zero nitrites with not more than 40 ppm. After that, you can slowly put your fish back into the tank and add the antibiotics to get rid of the fin rot.

  1. Loss of appetite

Loss of appetite can become the serpae tetra fish disease that commonly occurs. The symptom of loss of appetite is started by the losing of the appetite of the fish even though you feed them with various fish diets. To treat this loss of appetite, you can start by marking whether your tank is too small for your pet or not. If it is too small, you need to find another bigger tank. If there is no problem with the tank, you need to change the 25% of daily water in the tank for a week. Put the filter in the tank so that it can handle the waste. In a week you can see whether your fish slowly regain their appetite or not.
