Short description
Morfología | Morfometría
Radios blandos dorsales (total): 10-12; Radios blandos anales: 8 - 9; Vértebra: 32 - 33. Distinguished from other species of genus Characidium by the bright yellow fin coloration, and by the absence of conspicuous dark bars along the sides of body in
individuals larger than 3.5 cm SL (vs. dark bars or marks present on the sides of the body in specimens of all sizes in the remaining species of Characidium) (Ref. 76854).
Found mostly in riffles, rocky bed with pebbles and sand deposits (Ref. 76854).
