They are a hybrid species that includes convict (zebra) cichlids in their dna. Not something you want to add to a ram community tank. A no pair community for a parrot cichlid could work with convicts, jack dempseys, green terrors, some catfish and maybe, MAYBE, giant danios. This would be dependent on tank size what you could keep and each fishes temperament is. And all the same sex no need to hybridize further lol.
