Red-Bellied Piranha (Pygocentrus nattereri)

Pygocentrus nattereri

The Red-Bellied Piranha (Pygocentrus nattereri) is simultaneously the most famous and most misunderstood freshwater fish in the world. Decades of sensationalised media portrayals have cast this South American characin as a mindless killing machine capable of skeletonising a cow in minutes — a myth that bears almost no resemblance to the actual animal. In reality, P. nattereri is a nervous, schooling omnivore that spends most of its time hovering motionlessly in shaded water, startling at sudden movements, and eating seeds, fins, scales, and invertebrates far more often than it devours large prey. This The Fish Collection guide dismantles the Hollywood mythology and provides a rigorous, experience-based care manual for what is, in truth, one of the most fascinating and behaviourally complex aquarium fish available.
