📖 Overview

Facultative air-breathing in the genus ; Adults inhabit rivers and streams. Often occur in mixed schools with M. mysticetus which congregate around tree limbs and other solid objects, browsing the hard surfaces for zooplankton, crustaceans, aquatic insects and some plant debris. Move into the flooded forest during the flood season. Oviparous, distinct pairing possibly like other members of the same family . May be sold fresh or smoked on a skewer .
