The problems I'm having just keep piling up. My Red Bellied Pacu has become very aggressive lately. My Albino Oscar did a dumb thing and wen't to go bite the Pacu, but the Pacu got him by the jaw, and ripped it up pretty badly. Now he has beaten up the Channel Catfish so bad, that I had to take him out of the tank so he could heal. One of his barbels (Whiskers) was completely torn off. Any idea if it will grow back? He has a long time to heal yet, ripped fins, bitten face, ect. Things were going great, the Pacu had lived with the Channel for a little more than a year now with no issues, so this just started to happen.
