Orinoco Peacock Bass are named for the Orinoco river of Venezuela and Colombia, from which they originate. Like other Peacock Bass species, Orinoco Peacock Bass are found living in relatively strong flowing Amazonian rivers where they use the cover of branches, driftwood and plant vegetation to ambush a wide variety of prey items.
The waters of their native Orinoco river are very warm year round with temperatures reaching upwards of 86° when the sun is at its peak, and with nighttime temperatures still hovering around the 80° mark. Orinoco river waters conditions are acidic with a pH range of 5.0 to 6.5 and a water hardness between 5 to 15 dH; as well as, fast flowing with a large volume of water passing down from the mountains on its way to the ocean.
Cichla orinocensis have evolved perfectly for their environment with long sleek bodies and powerful pectoral and anal fins, which they use to maintain ambush positions in rapidly flowing waters and ambush prey. Orinoco Peacock Bass are becoming much more available within the aquarium hobby as their size, pattern, coloration and aggressive feeding habits have made them very popular with aquarium hobbyists interested in keeping larger New World Cichlid species.
