Notas de História Natural:

The two matrinchã species (Brycon amazonicus and B. cephalus) are both omnivores when adults with a preference for fruits and seeds. Adults are most abundant in blackwater and clearwater tributaries whereas young fish are confined to whitewater floodplains. Both species are also migratory and captured by fishing during spawning and dispersal migrations. During the low water period they often migrate to the lower courses of terra firme streams where they remain in pools.
