The Peacock Bass (Cichla orinocensis), also commonly known as the Peacock Cichlid, is a freshwater fish native to South America (where it it is known as the "pavon"), and introduced to Singapore and Peninsular Malaysia deliberately by anglers as a popular game fish. In the United States it is quite common in South Florida both in man made waterways and in the Everglades. An aggressive fish which preys on smaller native fish, it has been identified as a potential cause for ecological imbalance in its adopted habitats.

A member of the Cichlidae family, the large fish can grow 62cm in length, and can be identified by dark vertical bars on its body, as well as what resembles "peacock eyes" on the adult's tail fin, a feature which gave it its common name. The males have a prononced hump or bump on their foreheads once they reach adulthood, a feature not uncommon among cichlids.

As aquarium fish they are voracious and predatory, eating any smaller tankmates but are not too aggressive towards fish of similar size. They will only eat live foods.
