Where the name comes fromEdit
from the Ancient Greek νῆμα (nêma), meaning 'thread', in reference to the extended filamentous rays in the caudal-fin of member species, and βρύκω (brúkhō), meaning 'devour, gobble, bite, chew, gnash', a term which was originally used in reference to possession of fully-toothed maxillae but subsequently applied to the generic names of many characiform species in order to demonstrate their putative relatedness.
Nematobrycon lacorteiRainbow Tetra
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
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.
