Just got GBR last week.He has a sopt on his tail that looks like a fungus.I put him in the QT tank.Read some where that you must be extra carefull when medecating them. New to fish keeping so any advice would be greatly appeaciated and welcome.
Oh, it seemed like the sequence of events was that the fish developed the problem and then was put in a QT.
If its small and caught early, water changes should take care of it. However, I would get the med now so you have it if you need it. The second it gets worse I would medicate, and if it doesn't start improving after several water changes, then i would medicate.
