Cichlasoma octofasciatum

The Jack Dempsey cichlid is named for the 1920's boxer of the same name. The name alludes to its aggressive nature. Like most cichlids it is territorial, especially against its own kind and similar species. The fish was once very popular due to its striking appearance and personable mannerisms.

Like other Cichlasoma species the Jack Dempsey originates from Central America. In the aquarium it may reach about 8 inches long. The coloration changes as the fish matures from a light gray or tan with faint turquoise flecks to a dark purple-gray with very bright blue, green, and gold flecks. The dorsal and anal fins of mature males have long, pointed tips. Females lack these exaggerated tips.

Jack Dempseys are known to be attentive parents, pre-chewing food to feed to their offspring.
