ℹ️ Overview
The gulper catfish, also known by its scientific name Asterophysus batrachus, is a predatory fish native to the Negro and Orinoco river basins in northern South America. This species is known for its dark, often black or deep grey coloration and its unusually large mouth, which allows it to swallow prey whole. It belongs to the Auchenipteridae family, first described by Kner in 1858. Though relatively uncommon in the general aquarium hobby, the gulper catfish has gained popularity among enthusiasts of exotic and predatory fish due to its specific care needs and fascinating feeding behavior.
