General: The Peacock Bass (Cichla monoculus) is a member of the Cichlidae family that will not fail to impress with a colorful eyespot, and attentive behavior. This Cichlid can live past ten years, reach a length of over two feet, and weigh well over ten pounds.

Fecundity: The Peacock Bass (Cichla monoculus) can produce up to 15,000 eggs per clutch. The female will lay eggs on a flat surface where the male will fertilize them. The hatched fry will be relocated to a nest where the parents will guard the offspring.

Aquarium Diet (Carnivore): Feeder fish, Ghost Shrimp, Crayfish, Crickets, and Earthworms. Please only feed terrestrially-based foods such as Chicken, and Beef Heart on rare occasion as they can cause digestive issues within Peacock Bass.

Compatibility: The Peacock Bass (Cichla monoculus) will likely attempt to consume anything that will fit in its mouth. The Peacock Bass can be kept as an individual, or a pair.
