Very nice looking Grammodes, one of my favorite cichlids, the only thing is you can't put another cichlid in the tank with them, they are very aggressive...
I know people who kept them long-term with Vieja, Amphilophus and Urophthalmus. You just need a big tank. 500 gal or more. With enough space they tend to more relaxed with other fish and bother only about their own species.
