I had been treating my beta for mouth fungus for over a month and it seemed like his condition improved. Then last weekend when I went to feed him I noticed that half his upper lip was gone. I, on the advice of a friend, went out and bought him some stronger antibiotics. They have helped to clear up the fungus but the fish still has a nasty mouth wound and won't eat. What can i do to help him? Is there something soft I can feed him?
