I agree with Paratilapia polleni. My boyfriend used to have a female and they are aggressive though so watch them. I also agree with True Parrot Cichlids or, if you can source them, True Green Terrors(Andinoacara stalsbergi). Don't be fooled into buying Gold Saums(Andinoacara rivulatus) thinking they are GT's. GT's have white along the dorsal and tail not orange.
