Banded Bottlenose Catfish

Ageneiosus vittatus is a sizeable, active predator in the auchenipterid genus Ageneiosus, found in the Amazon basin of Brazil and Venezuela. It is distinguished from A. inermis by its pale vertical banding across a silvery body, giving it a subtly different but equally impressive appearance. Like all members of the genus, it is a mid-water open-space swimmer with a powerful build and predatory habits.

In the aquarium, Ageneiosus vittatus requires the same large-volume, powerful setups needed by A. inermis. It is highly active, especially in the evening hours, and should be fed large meaty items two to three times per week. A diet of whole fish, prawns, earthworms, and large frozen invertebrates keeps it in excellent condition. It will consume any fish small enough to engulf.

This species is best reserved for aquarists with experience managing large predatory fish. It can be housed with arowanas, large cichlids, and other robust catfish. Its banded pattern adds visual interest to a large predator display, and its bold, assertive behaviour makes it an engaging centrepiece fish.
