Pacu Fish

Pacus inhabit most rivers and streams in the Amazon and Orinoco river basins of lowland Amazonia, where they form part of the highly diverse Neotropical fish fauna. They have also recently been found in the riverine systems of Papua New Guinea, where it is believed the fish has been introduced to aid the local fishing industry. In August 2013 a Pacu was discovered in Scandinavian waters, a fisherman pulled a 21 cm (8.27 inch)specimen from Øresund Sound off Sweden's south coast.
