I call him killer, because he will try and kill any tank mates as soon as you add him. He is in solitary confinement in a 25g right now, but hope to move him to a 180g w/ other CA cichlids. He is about 6-7'' long and feel this tank is too small for the long term. I did give him a swordtail to chase around. He hates swordtails more then any other fish lol..
