I have two discus fish and they have waste strining behind them and one fish is actually reacting quite badly. I have been doing water changes and treating them with and internal bacterial infections medication that is supposed to work;however, it is not. Any advice from any experts out there
Make sure your water parameters are correct, you dont want a sick fish suffering even more with higher levels of ammonia or nitrite. also make sure your temp is around 30 degrees celcius - about 82 -84 farenheit. keep the water clean like youre doing. Someone else might know what good meds there are to help your fish.
