Cataniapo

Geophagus dicrozoster is a cichlid from tributaries of the río Orinoco in Venezuela, extending to the Casiquiare and the headwaters of the Negro. Commonly traded but rarely under the correct name, it is usually sold as G. altifrons or G. surinamensis, and it is one of the few Geophagus bred commercially. Seven flank bars, the fourth and fifth meeting in a 'Y', and a relatively elongate profile identify it. It appears restricted to acidic blackwater.

Geophagus taeniopareius is a cichlid from the Venezuelan upper Río Orinoco, recorded from tributaries including the Caura, Cataniapo and Ocamo. Known in Germany as the 'Wangenstrich-Erdfresser' (cheek-stripe eartheater), it has been in the hobby since the late 1970s. A dark stripe runs from the eye to the corner of the opercle. It is markedly more aggressive than most congeners and spawns on the substrate.
