Description
The Iguazu Catfish, likely *Rhamdia quelen*, is a large, predatory freshwater catfish native to the Iguazu River basin and other South American waterways. Known for its robust, elongated body and prominent barbels, it is an opportunistic nocturnal hunter. This species requires a spacious aquarium due to its potential size and semi-aggressive nature.
