Although this fish superficially resembles a piranha and belongs to the same subfamily, the Pacu is a plant-eating species rather than a predator. It is a large fish that is bred commercially both for aquaria and as a food fish, and it is quite unsuitable for most home aquaria. However, in its proper setting, the species is long-lived and well worth keeping.
- Widespread in the Amazon region.
- Around 16in (40cm).
- Peaceful, despite its size; has a keen appetite for plants.
