'Geophagus' pellegriniYellowhump Eartheater
Cichlidae · Regan, 1912
The yellowhump eartheater, Geophagus pellegrini, is a cichlid from the Chocó and Antioquia departments of northwestern Colombia. The species is rare in the hobby, and most fish traded under its name are forms of 'G.' steindachneri or occasionally 'G.' crassilabris. Its yellowish colour pattern separates it from those two, the other members of the 'G.' steindachneri group. It is an ovophilous, maternal mouthbrooder.
Nematobrycon lacorteiRainbow Tetra
Characidae · Weitzman & Fink, 1971
The rainbow tetra, Nematobrycon lacortei, is a small characid from western Colombia, considered endemic to the Río San Juan system. All records appear to come from the Río Calima, where it is apparently restricted to small, isolated forest pools. It is very close to N. palmeri in morphology but has a highly distinctive colour pattern, and adult males are territorial to an extent.
Nematobrycon palmeriEmperor Tetra
Characidae · Eigenmann, 1911
The emperor tetra, Nematobrycon palmeri, is a characid endemic to the San Juan and Atrato basins in Colombia. Virtually all fish in the trade are captive bred, and it is hardy and unfussy about water chemistry. Males are told apart from N. lacortei by their blue iris, and the smaller Inpaichthys kerri, often misidentified as this species, has an adipose fin, which Nematobrycon lacks.
