Catfish | Upside Down Catfish (Synodontis nigriventris)
The Upside Down Catfish, scientifically known as Synodontis nigriventris, is a unique and entertaining freshwater catfish famous for its habit of swimming belly-up beneath driftwood and decor. Native to Central Africa, this species uses its upside-down swimming behavior to graze on food from the undersides of surfaces.
Peaceful and hardy, Upside Down Catfish are excellent additions to community aquariums and do best when kept in small groups, where their natural behaviors really shine. Their spotted brown-and-cream pattern provides subtle beauty, while their behavior adds constant interest.
