Upside-down catfish, Synodontis nigriventris, is a species of catfish. It's particularly noteworthy because of its habit of swimming upside down most of the time. This is reflected in the fish's pigmentation—their bellies are darker than their backs.

The upside-down catfish is well suited to aquariums because of its small size (typically 9 or 10 cm or less) and peaceful demeanor. It fares best in schools of up to half a dozen.
