Observaciones | Inhabits pools and runs over gravel and cobble in rivers flowing through undisturbed forests (Ref. 12693). Juveniles were most commonly collected in or near rapids (Ref. 27732). Found in small rivers and streams during the dry season. Moves downstream at the onset of the rainy season, but generally avoids turbid waters. Migrates upstream after two months and spawns in July near the mouths of small streams that the young subsequently ascend. Omnivorous, feeding on both animal and vegetable matter, at times consuming toxic fruits in flooded forests, making them temporarily inedible.
