My leporinus has developed an very carnivourious attitude, and he recentally took my ghost catfish ( 4 inches) down and is eating him this very second.
Sorry to hear that. I had one once,it was given to me for free. It had the same kind of attitude till i put him in with fish that were bigger than him. He smartened up real fast after that and didnt want to pick on anyone any more. Sorry for your loss
