Inhabits pools
and runs over gravel and cobble in rivers flowing through
undisturbed forests. Juveniles were most commonly collected
in or near rapids. 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. |
