In the aquarium

O. niger is a popular aquarium fish species. In the hobby, it goes by many names, including black talking catfish, razorback catfish, mother of snails catfish, ripsaw catfish, and black doradid. This species grows to a large size and are often bought by unsuspecting aquarists when small. They will rapidly outgrow smaller tanks, so the aquarium should be as large as possible. O. niger is especially light shy and should be provided with sheltered areas to hide. Although these fish are peaceful, very small tankmates are still at risk of being eaten. This species readily accepts prepared foods. O. niger has not been bred under aquarium conditions.
