However, a number of other fishes may also be known by this name:Brachysynodontis batensoda - Giant upside-down catfish.Mystus leucophasis - Asian upside-down catfish.Synodontis angelicus - spotted upside-down catfish.Synodontis aterrima - Sometimes sold as Synodontis nigriventris in the aquarium trade but not identified as a separate species by retailers.Synodontis contracta - Big-nosed upside-down catfish, sometimes sold as Synodontis nigriventris to aquarists, a species with which it is easily confused.Synodontis nigrita - False upside-down catfish, very commonly sold as Synodontis nigriventris in the aquarium trade and only recognised as a different species once the fish matures (adults are more than twice the size of adult Synodontis nigriventris).
