DISTRIBUTION/HABITAT: Tropical. South America: Amazon and Orinoco River basins in open water of large rivers and seasonally flooded forests.

DIET IN THE WILD: Insects and decaying fruits and vegetation that fall in water. (Do these fish celebrate the inevitable last flight of a bola butterfly?)

REPRODUCTION: External fertilization. Although parents abandon their eggs, pacu are brood- hiders, minimizing the chances of the clutch being discovered by predators.
Lifespan to 25+ years.

CONSERVATION: IUCN Red list; Not evaluated CITES No special status

REMARKS: Because pacu are closely related to piranha, sharing their coloration and shape, Hollywood producers have been known to use the pacu as a stand-in for piranha. Actors are appreciative of the pacu’s preference for vegetable matter.

Pacu’s dentition allows them to crush fruit, nuts and seeds. Their teeth are cusped and resemble human molars, and they also have very powerful jaw. Can cause serious bites.

Like the tambaqui, an important aquacultured food fish in South America.
