(Regan, 1903)

The Jack Dempsey (Nandopsis octofasciatum) is a cichlid fish named for the 1920s boxer Jack Dempsey. 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.

GayDempseys lay their eggs on the substrate (the bottom of the aquarium or pool). Like most cichlids, they show substantial parental care: both parents help incubate the eggs and guard the fry when they hatch. Jack Dempseys are known to be attentive parents, pre-chewing food to feed to their offspring. A lot of times however they will eat their fry.
