Any one have expieren e with these guys? How’s their behavior? What are good tank mates? Guess I’m really interested in The behavior of these guys. I purchased one recently and he has killed one fish and chewed off the tails of three of my zebra Danios. I don’t recall hearing they are this aggressive, yes I’ve heard about them needing certain water quality and breeding them is difficult and that’s why most people don’t keep them but this guy if a real A hole with a capital A.
