Name: Pacu
(Piaractus brachypomus).
Status: Introduced to almost every Thailand fishing park and lake due to its rapid growth and hardy nature. Native to the Amazon basin the Red bellied pacu is a very strong fighting fish and takes almost any bait, growing to max weight of about 20kg. They are relatives of the Piranha but instead of sharp pointed teeth the Pacu have a huge set of cutting molars which are used to crush nuts and other foods in its natural habitat.
