Diagnostic Description
provided by Fishbase
body depth 2.9-3.7 x SL, anal base 3.2-4.7 x SL, caudal peduncle height 13.3-19.3 x SL. Eye diameter 2.7-4.6 x head length. Uniformly brilliant silver color, sometimes grayish or brownish.
Life Cycle
provided by Fishbase
Builds a nest for the eggs. No guarding or tending has been observed, though.
Migration
provided by Fishbase
Potamodromous. Migrating within streams, migratory in rivers, e.g. Saliminus, Moxostoma, Labeo. Migrations should be cyclical and predictable and cover more than 100 km.

Morphology
provided by Fishbase
Dorsal spines (total): 0; Dorsal soft rays (total): 21 - 28; Analspines: 0; Analsoft rays: 27 - 35
Trophic Strategy
provided by Fishbase
Feeds on insects (Ref. 3681).
Biology
provided by Fishbase
Affinities: P. pellegrini. Generates electric organ discharge (EOD) of short duration that seems to correlate with aggregative behavior of the species (Ref. 14060; 10601). EOD temporal pattern cues have been shown to play a role in species recognition for P. bovei (Ref. 10600). A ratio measure between olfactory and visual receptor areas suggests that this species relies more on visual than olfactory information (Ref. 10839). A fractional spawner (Ref. 10605; 10606).
