Short description
Morfologia | Morfometria
Robust body, with moderate depth; slightly oval. Gonopodium long with apex not reaching the base of the tail. Sides with 8 - 10 dark bars, especially evident in males and young. Ground color is brown, dorsal fin has a black blotch posteriorly (Ref. 36880).
Inhabits slow flowing waters that are only rarely deeper than 30 cm and connected to standing marshy area; over muddy bottoms (Ref. 26130, 36880). Lives between 35 and 600 m elevation at temperatures of 23-30°C. Swims in small groups near the surface of turbid waters, on the shoreline or among the undergrowth. Feeds on unicellular algae, diatoms, ooze and sometimes insect larvae (Ref. 36880).
