Also in the Characidae family, Piaractus mesopotamicus is the specie known as pacu in northern of Argentina. This powerful round-shaped fish can get seriously big. Like Pirá Pitá, Pacú are omnivorous, and chances are you might find them surface feeding on fruit or insects—producing perfect sight-fishing scenarios. Finding a big Pacú eating slowly on the surface, under a tree, for instance, can be thrilling Pacú rarely jump, but their size, strength and prodigious runs put them in the hard-fighting class. In general, they’re considered an elusive catch and they’re often compared to permit. Fifteen plus pound fish are typical, but they can get much larger.
