I have an A. MaCmasteri that has contracted a bad case of fungus that started on his dorsal fin and has spread despite treatment. (He was beaten up and the disease started when I moved him to a different tank as a form of protective custody).
I have been using the greenish stuff (Fungus Cure from Aquar. Pharm.). It's main ingredient seems to be "neutroflavin." It has not helped. Any other suggestions? Would salt help?
