My dwarf gourami seems to have a little white tuft of fuzz around his mouth...could this be Mouth Fungus? It wasn't there this morning. He doesn't seem to be eating much either, but it is hard to tell. If this is the case, do you think I should treat with penicillin? Does the fish store sell this sort of thing? Please help if you can before I lose this fish.
