Jack Dempsey Fish Guide
The Jack Dempsey (Rocio octofasciata) is a striking freshwater cichlid named after the famous boxer because of its strong facial features and bold presence. It is popular in aquariums thanks to its rich colors (iridescent blues, greens, and golds) and its lively personality. What makes it unique is the combination of its beauty, its somewhat challenging temperament, and the fun of giving it a well-decorated home where it can dig and claim a territory.
