Serrasalmus humeralis

Serrasalmus humeralis, commonly encountered in river systems of the Amazon Basin, is distinguished by its robust body and distinctive humeral spot. Despite its common name as a type of piranha, it is primarily herbivorous in the wild, feeding on fruits, seeds, and occasional small fish or insect larvae. It is important to maintain a stress-free environment with sufficient hiding spaces in captivity. Due to Serrasalmus humeralis's potential for aggressive territorial behavior, they are best kept singly or with very specific compatible species in larger tanks.
