Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 4; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 65 - 71; Ryggkotor: 47 - 52. Head width 11.7-13.6% SL; caudal peduncle depth 5.2-5.9% SL; anal fin rays 65-71; and vertebrae 47-52 (Ref. 52514).
Occurs most frequently in large slow-flowing rivers and lakes. Migrates into inundated forest during periods of high water, where it can be found around submerged woody vegetation. Feeds on fishes and crustaceans (Ref. 52514).
