Jello Band Catfish

About

Found in the Cenepa River basin of Peru, a tributary system within the broader Amazon drainage, Aguarunichthys torosus is a hefty, predatory catfish that goes by the trade names 'Jello Band' or 'Yellow Band' catfish among hobbyists. It grows into a substantial fish, adults commonly reach well over a foot in length, and it has the body to match, with a robust, muscular build that lives up to those dimensions. In the aquarium, its personality is best described as assertive: anything small enough to disappear into its wide mouth probably will, and it holds strong territorial opinions toward others of its own kind. Because of that aggression toward conspecifics, keeping a single specimen is by far the more practical approach. Where it can work well is in a community of similarly sized, river-adapted species that can hold their own without getting into direct conflict. The tank needs to be spacious to accommodate both its adult size and its territorial nature. It falls into the intermediate care category, partly because sourcing appropriate tankmates takes some thought and partly because its diet and water quality needs require consistent attention. Not a fish for a crowded or unplanned setup, but a rewarding one for a keeper who plans around it.
