Piranhas Fish in England

Piranhas are native to South America and are commonly found in countries such as Argentina, Brazil, Bolivia, Colombia, Ecuador, Guyana, Paraguay, Peru, Uruguay, and Venezuela, inhabiting rivers like the Amazon, Paraguay, and Paraná.

Piranhas can show aggression, especially when in large groups, during times of hunger, or when protecting themselves or their spawning sites, but they generally do not attack humans unless they feel threatened.

Piranhas have several natural predators including larger fish, birds like herons and kingfishers, caimans, anacondas, and aquatic mammals such as otters, which help control their populations in their natural habitats.
