I had 4 convicts (2 females and 2 males) in my tank, one female died and the other one had babies. Now the males are beating each other up. My one single one is beaten up hardcore, his tail is gone, his fins are hardly there and his scales are peeling off. I seperated him and placed him in a different tank and he's doing alright now but still looks just as horrible. Is there ANYTHING I can do to make him better or will it just take time for something to happen??
