It is found in the lower Tocantins and Araguaia Rivers of Brazil.[2][3] The species is notable for being the one of only the members of the genus Serrasalmus that can coexist with others of the same species in captivity, however caution is advised. Gery's Piranha reaches sizes up to 12 inches in length. As of 2018, it is classified as Least Concern by the International Union for Conservation of Nature.[1]
