Μαλακές ραχιαίες ακτίνες (συνολικά) : 7 - 9; Μαλακές εδρικές ακτίνες: 8 - 19. Body extremely compressed; lateral line strongly decurved; scaleless keel along belly from pelvic to anal fin; dorsal- fin origin behind pelvic-fin origin; mouth small, upturned on pointed snout; appears silver in clear and turbid water, and gold side and fins in coffee-colored water; fins red in southern hemisphere; dusky stripe along side, herringbone lines on upper side of young. Scales on lateral line 44-54; dorsal fin with 7-9 rays; anal fin with 8-19 rays, usually 11-14; rakers on 1st gill arch 17-19; and pharyngeal teeth 0,5-5,0 (Ref. 86798).
Inhabits vegetated lakes, ponds, swamps, backwaters and pools of creeks and small to medium rivers (Ref. 86798). Can tolerate low oxygen levels, high turbidity and high temperature; omnivorous but principally feed on plankton, insects and mollusks (Ref. 27549).
