The Jack Dempsey cichlid (Rocio octofasciata) is a truly iconic and striking freshwater fish, renowned for its vibrant personality and beautiful, ever-changing coloration. Originating from the slow-moving waters of Central America, this species is a popular choice for experienced aquarists seeking a robust and engaging centerpiece for their large aquarium.Adult Jack Dempseys typically reach an impressive size of 8-10 inches, developing a deep, stocky body. Their base coloration is usually a dark gray or brownish-purple, heavily adorned with iridescent blue, green, and gold spangles that shimmer under proper lighting, creating a captivating spectacle. As they mature, their colors intensify, and males often develop more elongated dorsal and anal fins. However, their most famous feature is their temperament; named after the famous boxer, Jack Dempsey cichlids are known for their assertive and territorial nature. They can be quite aggressive, especially during breeding or if kept in an undersized tank.Therefore, a minimum tank size of 55 gallons for a single specimen, or 75+ gallons for a pair or community setup, is essential. They thrive in well-filtered water with a temperature range of 75-82°F (24-28°C) and a slightly acidic to neutral pH of 6.5-7.5. Provide plenty of caves, rocks, and driftwood for shelter and territory demarcation, but ensure stable, heavy decor that won't be easily rearranged, as they are notorious diggers. A varied diet of high-quality cichlid pellets, flakes, and occasional live or frozen foods like bloodworms, brine shrimp, and small earthworms will keep them healthy and vibrant. While they can be housed with other large, semi-aggressive to aggressive cichlids or robust species like larger plecos, careful consideration and ample space are crucial to prevent conflicts. The Jack Dempsey is a magnificent fish for those ready to commit to its specific needs, rewarding its owner with a dynamic presence and a truly stunning display.

Very aggressive, especially when mature.
