Mayan Cichlid

The Mayan cichlid takes its name (urophthalmus: "tail eye") from the large, light-ringed eyespot on its caudal peduncle. Its olive-green or yellowish body has six or seven dark vertical bands; during breeding the throat and lower body turn reddish–orange. It is extraordinarily hardy: it adapts to everything from fresh water to brackish lagoons, and even to salinity close to that of seawater. For this reason, individuals released into the wild in Florida have formed permanent, invasive populations; it must never be released into the wild.

• At least 300 liters and 150 cm of length for a pair.
• Large rocks, caves and roots; it digs the substrate and uproots plants.
• Moderately hard, alkaline water; there is no need to add salt to the aquarium.
• A 30% water change weekly; a powerful filter.

Omnivorous. Make cichlid granules the staple; vary them with frozen shrimp, mysis, bloodworms and vegetables.

Territorial and aggressive, especially during breeding; it eats fish, shrimp and snails that fit in its mouth.

Good companions: robust Central American cichlids of similar size, large plecos; in a large aquarium.

Avoid: small and peaceful fish, shrimp, snails, calm South American cichlids.
