Can my 6" plecco go in the same tank as my 8" Red Devil? I think he might eat it but was wondering if anyone had some experience with this. He's REALLY aggressive and attacks anything that enters the tank. He'll even attack things that aernt alive like rocks and wood just to see if they might possibly be food. He also likes to attack fingers, hands, faces, seriously he attacks anything that gets close to the tank. Also he's in a 55 right now.
