The sharphead eartheater, Satanoperca acuticeps, is a cichlid from the central Amazon basin in Brazil, including the lower rio Negro and rio Branco. Relatively rare in the trade, it is sometimes confused with S. daemon and S. lilith but has three dark flank blotches (vs. two in S. daemon, one in S. lilith). Unless breeding it is surprisingly peaceful, and it is very rarely bred in aquaria.
