Nanay Dorado Catfish (Brachyplatystoma rousseauxii)


Although many large Amazon catfish are known as “Dorado”, this species is among the largest growing and most distinctive. With its uniform metallic silver coloration and torpedo-like hydrodynamic shape, the Dorado is an impressive fish, but one suitable only for enormous custom aquariums or large indoor ponds. In the wild, this fish inhabits deep stretches of turbid, sediment rich rivers and streams, where it relies on its sensitive barbels to find and catch prey. Like many of the giant Amazonian catfish, they are sensitive to water quality and will require massive filtration and regular large water changes to thrive. A fish for experienced, specialist aquarium hobbyists with the resources to keep them long term only.
