Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 0; Espinhos anais: 0; Raios anais moles: 51 - 68. Diagnosis: adipose fin present; inner side of pectoral spine feebly serrated, with small to very small serrations; 51-68 soft anal fin rays; vomerine teeth usually absent; a dark triangular blotch at base of caudal fin (Ref. 43912, 81643).
Body shape (shape guide): elongated; Cross section: oval.
Confined to large and moderate rivers; sometimes penetrates into estuaries; gregarious schooling species, such schools probably an important prey for several larger carnivorous species (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Maximum TL reported 85 mm (Ref. 43912).
