Parachromis dovii, the wolf cichlid, rainbow bass, or guapote, is a species of cichlid native to Central America, where it occurs in lakes, rivers and streams in Honduras, Nicaragua and Costa Rica.

[1] It is one of the largest cichlids, reaching up to 14 kg (31 lb) in weight and 80 cm (2.6 ft) long.

[2] P. dovii is important to local commercial fisheries, is sought after as a gamefish,[2] and is sometimes kept in aquariums.

[4] The fish is named in honor of John Melmoth Dow (1827–1892) of the Panama Railroad Company.

While they are noted for their relatively high intelligence and lifespan of up to a few decades, they require special care due to their large size and high levels of aggression even by cichlid standards, meaning that few — if any — tank mates are possible.
