Previously included as a member of the genus Cichlasoma, the red devil is often confused with the midas cichlid, A. citrinellus. The two can be distinguished through differences in morphology. As suggested by its scientific name, A. labiatus possesses characteristically large lips, although in reality this is variable and should not be used as a defining indicator of species. Certainly, tank bred fish tend not to have these large lips. More reliable differences include the bigger nuchal hump and mo…

More reliable differences include the bigger nuchal hump and more thick-set appearance in A. citrinellus.
