Upside-down catfish

Upside-down catfish

The name upside-down catfish is most commonly used by aquarists to refer to the mochokid catfish "Synodontis nigriventris" alternately known to ichthyologists as the blotched upsidedown catfish.cite web|url=http://www.fishbase.org/comnames/CommonNamesList.cfm?ID=9599&GenusName=Synodontis&SpeciesName=nigriventris&StockCode=9922|title=Common Names of Synodontis nigriventris|accessdate=2007-06-18] However, a number of other fishes may also be known by this name:

*"Brachysynodontis batensoda" - Giant upside-down catfish.David Sands (1986). A Fishkeeper's Guide to African and Asian Catfishes, pp 40-41. Salamander Books ISBN 0-8610-1211-9.]
*"Mystus leucophasis" - Asian upside-down catfish.cite web|url=http://www.planetcatfish.com/catelog/species.php?species_id=21|title=Synodontis contractus|accessdate=2007-06-18]
*"Synodontis angelicus" - spotted upside-down catfish.cite web|url=http://www.fishbase.org/comnames/CommonNamesList.cfm?ID=9536&GenusName=Synodontis&SpeciesName=angelicus&StockCode=9859|title=Common Names of Synodontis angelicus|accessdate=2007-06-18]
*"Synodontis aterrima" - Sometimes sold as "Synodontis nigriventris" in the aquarium trade but not identified as a separate species by retailers.David Sands (1986). A Fishkeeper's Guide to African and Asian Catfishes, p 58. Salamander Books ISBN 0-8610-1211-9.]
*"Synodontis contracta" - Big-nosed upside-down catfish, sometimes sold as "Synodontis nigriventris" to aquarists, a species with which it is easily confused.cite web|url=http://www.planetcatfish.com/catelog/species.php?species_id=414|title=Synodontis contractus|accessdate=2007-06-18]
*"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").David Sands (1986). A Fishkeeper's Guide to African and Asian Catfishes, p. 67. Salamander Books ISBN 0-8610-1211-9.]

The name dwarf upside-down catfish is also used for small (around 10 cm) species of the catfish genus "Synodontis". In the aquarium trade, the name is almost always applied to "Synodontis nigriventris" or species with which it may be confused, such as "Synodontis aterrima", "Synodontis contracta", and juvenile "Synodontis nigrita" (adults of which are around 20 cm so are not "dwarf" species at all).David Sands (1986).
