The small gap between supra-occipital process and basal bones of dorsal fin spine help visually differentiate this species from the similar M.atrifasciatus. It is also distinguished from the similar M.bleekeri by the much less conspicuous and non-indented fontanel, and the lack of dark tympanic spot. (Grant 2009). Habitat: 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.
