The Jack Dempsey Cichlid (Rocio octofasciata) is a large, aggressive freshwater fish known for its striking appearance and vibrant colors, ranging from blue and green to purple with dark spots. It typically grows to 10-12 inches in length and is highly territorial, making it best suited for experienced aquarium owners. Jack Dempseys prefer warm, slightly acidic water and require a large tank (at least 55 gallons). They are omnivorous, feeding on pellets, live foods, and vegetables. While their bold personality makes them fascinating, their aggressive nature means they need carefully selected tankmates.
