Upside-down catfish, Synodontis nigriventris, is a species of catfish. It is particularly noteworthy because of its habit of swimming upside down most of the time. Upside-down catfish originate from the Central Congo basin of Africa.[1]

Appearance and anatomy

Upside-down catfish are small, reaching a maximum of 9.6 centimetres (4 in).[1] Like other members of the mochikidae family, they have large eyes, a large dorsal fin and three pair of barbels. Upside-down catfish are adapted to spend most of their time upside-down. This is reflected in the fish's pigmentation—their bellies are darker than their backs, a form of countershading.[2]

Ecology

These fish are mostly nocturnal, and feed on insects, crustaceans, and plant matter.[1] These fish lay eggs.[1] The young fish do not swim upside-down until they are about two months old.[3]

In the aquarium

The upside-down catfish is well suited to aquariums because of its small size (typically 9 or 10 cm or less) and peaceful demeanor.[2] They should be kept in schools of 3 minimum for best effect. They should be fed a variety of good quality flake food, tablet food, frozen bloodworm and livefood as daphnia. Provide caves or ledges to them to loaf in.
