The Jack Dempsey (Rocio octofasciata) is a species of cichlid fish that is native to freshwater habitats from southern Mexico to Honduras, but also introduced elsewhere. [3] [4] [5] Its common name refers to its aggressive nature [6] and strong facial features, likened to that of the famous 1920s boxer Jack Dempsey.
Říčan's study suggests that the Astatheros species are more closely related to the Jack Dempsey and rainbow cichlid than to the remaining Amphilophus species. [2] Several species from this genus are endemic to the small Lake Apoyo (6 species) and Lake Xiloá (4 species) in Nicaragua, and are believed to be the result of sympatric speciation. [4]
This species has a specialized diet, feeding on the fry and larvae of other cichlids. [2] It reaches a total length of 17.9 cm (7.0 in). This species is also seen in the aquarium trade and sometimes goes by the name Haplochromis Jack Dempsey. [3] It is currently the only known member of the genus Naevochromis. [4]
Cichlids have a great variety of behaviors associated with substrate brooding, including courtship and parental care alongside the brooding and nest-building behaviors needed for pit spawning. Cichlids' behavior typically revolves around establishing and defending territories when not courting, brooding, or raising young.
