Nice wolf! Unfortunately, if your wolf is the same size as the oscar and JD then he won't have a problem tearing them up tonight. I strongly advise keeping the wolffish separately as eventually the wolf will be the only fish in the tank if not too small initially.

I'm glad to hear the encouragement on the tankmates. I'm a little scared of letting him into the main tank. He's in QT for the moment. The LFS had him on worms so at least he isnt used to eating fish. I read one thread saying they dont get super aggressive until they're about a foot. Any thoughts on that one?
