Biologie     Verklarende woordenlijst (b.v. epibenthic)

Adults inhabit 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. Move downstream at the onset of the rainy season, but generally avoid turbid waters. Mature individuals migrate upstream after two months and spawn 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.
