I spoke too soon Mark, overnight he turned into a holy terror lol. This morning he was just chasing the rest of the peacocks around relentlessly, so now he's in a time out. I switched him to the Mbuna tank for a bit and after getting chased a bit himself by the zebras now he seems to ha settled down quite a bit. I think I'll let him cool his jets a bit more overnight and then try to reintroduce him into the peacock tank again.
