Red piranha

The Red piranha, also known as Pygocentrus nattereri, is a species of freshwater fish notable for its reddish tint, especially under the belly and around the face, which contrasts with its darker back. Originating from South America, particularly from the Amazon Basin, the Paraguay-Paraná, and Essequibo Basins, this species is well recognized for its sharp teeth and somewhat aggressive reputation. Despite its fearsome reputation, the Red piranha is of significant interest in the aquarium hobby, although it requires experienced handling due to its specific care needs and potential aggressiveness.
