Habitat and Ecology [top]

Habitat and Ecology:P. intermedia is a pelagic species that inhabits pools of clear, well-shaded streams and river margins in slight to moderate currents; with substrates of mud, sand, rock, leaves and fallen branches. It is generally found in loose aggregations in eddying currents or rapids, and sometimes leaps up out of the water to capture flying insects. Young occur in large numbers in the crevices of rocks along the banks, out of the current. After about 28 days gestation, only 5 to 20 young are born. This species is a live bearer, and has a high survival of young.

Threats [top]

Major Threat(s): Logging and deforestation in basin, but not likely affecting this prolific species.
