Currently, I've got a 6" male trimac with a community of cichlids in a 1000g tank. He does a little too much chasing and some bullying already so I'm planning on moving him to a 6' 135g tank in my office. Are there any other Central American cichlids that would work long term in a tank that small? Salvini, Cryptoheros, Thorichthys, Amititliana sp perhaps?
