The Upside Down Catfish (Synodontis nigriventris) is a well-known and highly adaptable freshwater catfish native to Central Africa, particularly the Congo River Basin. This small, peaceful Synodontis species gets its name from its unique swimming style — often gliding upside down to feed from the water surface or underside of driftwood and leaves. With its mottled brown-and-cream body pattern, playful personality, and excellent community compatibility, the Upside Down Catfish is a favorite among aquarists.
