The Cooper Creek catfish, Neosiluroides cooperensis, also known as the Cooper Creek Tandan is a species of catfish (order Siluriformes) of the family Plotosidae, and is the only species of the genus Neosiluroides. The species’ scientific name Neosiluroides came from the genus Neosilurus to which the Cooper Creek Catfish bears some resemblance. The second part of its name, cooperensis, is a reference to the sole location of the species in the Cooper Creek Catchment. It is an eel-tailed freshwater fish that resides in the Cooper Creek system of the Lake Eyre drainage in southern Queensland, Australia. This species grows up to about 46.0 centimetres (18.1 in) SL.
