Here are some key characteristics and care requirements for the Rainbow Cichlid: Appearance: They are known for their golden to orange bodies with a black horizontal bar and can change color. Size and Lifespan: They typically reach 11-12 cm (4.33-4.72 inches) in length and can live for 7-8 years. Tank Setup: Tank Size: A minimum tank size of 90 cm (36 inches) is recommended for a pair, with a 55-gallon tank being ideal. Larger tanks are needed for groups. Substrate: A sandy substrate is preferred as they like to dig. Decorations: Include rocks, driftwood, and plants for hiding places. Water Conditions: Maintain temperatures between 22-29°C (71.6-84.2°F), a pH of 7-8, and water hardness of 10-20°N (178.57 – 357.14 ppm). Diet: As omnivores, they should be fed high-quality cichlid food supplemented with live or frozen foods and vegetable matter. Temperament and Tankmates: They are generally peaceful and can coexist with other non-aggressive fish of similar size. Breeding: They are pair-bonded substrate spawners and are relatively easy to breed. Both parents care for the eggs and fry.
