Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6 - 7; Anal spines: 0; Anal soft rays: 17 - 24.

Adults inhabit rivers and lakes to at least 400 m elevation (Ref. 2847) at temperatures ranging from 26 to 32°C. May have migratory habits. Mainly diurnal. They feed primarily on large insect larvae and emergent and terrestrial insects, and also crustaceans excluding prawns.
