This little guy has been terrorizing my entire tank full of cichlids and has nearly killed A flowerhorn and a green terror.. I'm trying to figure out why it only chases and trys to kill only the females in the tank but yet only allows the female convict anywhere near it. I thought it was a male but now I'm not sure. Any help is appreciated. I'm trying to get my tank separated cuz of the fish getting bigger and the aggression.
