I've got a 7 inch green terror that likes to think he is in charge of the tank, and will challenge my 9 inch oscar to a fight he can't win. They will do the old mouth lock, and typically the damage is minor. But last time the oscar took quite a chunk out of the terrors lower lip. He's got a chunk of bone or tissue of some kind sticking out of his lip. I'm not sure what fish have in their lower lips, but whatever it is, it's really sticking out. I'm not sure what to do about it. Seems like it's too far out to heal over. Trying to clip it off seems overly traumatic ? He still eating alright, and is not showing any obvious signs of distress. Needless to say he hasn't tried to pick a fight with the oscar since then. Any advice?
