Morphology | Morphometrics
Body color dull black on back and upper sides of body, silvery white on lower sides and belly; with a markedly black stripe along lateral line. Origins of dorsal and pelvic fins opposite each other and located at the center of body; pectoral and pelvic fins short and small. Head small, pointed and slender; mouth large, corners reaching front edge of eyes and slit slanted (Ref. 45563).
Adults live in upper reaches of rivers, often in groups in search for food. They feed on larvae of aquatic insects, diatoms and filiform algae (Ref. 45563). Utilized for food (Ref. 80318).
