There are also many other great gamefish throughout the Amazon depending on the specific fishery.  Each river in the Amazon system has it's own particular mix of game fish.  Among the more notable Amazon denizens are the huge arapima (pirarucu) and the glittering, prehistoric-looking aruana.  The arapima must come to the surface periodically to gulp air in order to survive.  Picture a 100 pound plus scaled giant surfacing near your boat in a glass smooth lagoon!  Many of the rivers contain giant red-tailed catfish ('pirarara'), sometimes exceeding 100 pounds.  These monsters can be caught using a piranha as bait (you'd better have stiff gear or be prepared to follow these leviathans down the river).  Some fisheries contain the fast and acrobatic 'matrincha'.  Suribim are large, aggressive catfish that happily strike a plug.  Amazon rivers are also home to beefy 'pacu', toothy 'bicuda', streamlined 'pike cichlids' (Crenicichla sp.) and lots of small but feisty piranha.
    Some of the best trophy peacock bass rivers do not offer a wide variety of 'incidental' species.   If you're after a mixed bag and not specifically seeking trophy-sized peacock bass, consider one of our amazing variety trips such as the Rio Travessao in the Brazilian highlands, with it's mix of payara, trairao, bicuda, peacocks and giant catfish, all accessible from one camp.
