Overview
Family: Serrasalmidae
Pacu are massive, powerful freshwater fish native to South America, closely related to piranhas but far more peaceful. The most common species kept in Australia are the Red-Bellied Pacu and Black Pacu, both of which can grow over half a metre long. They are intelligent, hardy, and social fish that recognise their keepers and can live for decades in large, well-maintained aquariums or indoor ponds. Despite their calm nature, their size and appetite require serious commitment and space.
