Salminus brasiliensis (dorado, golden dorado, river tiger or jaw characin) is a large, predatory characiform freshwater fish found in central and east-central South America. Despite having Salminus in its name, the dorado is not related to any species of salmons, nor to the saltwater fish also called dorado.
The golden dorado generally prefers water temperatures between 20 and 28 °C (68–82 °F). Is native to warm freshwater habitats in southern Brazil, Paraguay, Uruguay, Bolivia and northern Argentina. One of the best spots is the Parana and the Esteros del Ibera, in the province of Corrientes, Argentina.
