So I have a question as it pertains to someone else's fish, water parameters are perfect, tank mates are 1 other green severum, 3 parrots, 1 Oscar, 1 black ghost and a green Texas, his fish has a wond on his head that looks really bad and I honestly don't know the advice to treatment or even what it is, it looks like fighting wounds but I'm not to sure, I was thinking hole in the head disease but I'm not sure about that either, he wants to do melafix but I honestly can't give him the correct advice. Any help would be appriciated.
