Tandamus Catfish

Tandanus Catfish (Tandanus tandanus)

A true Australian native, the Tandanus Catfish (also known as the Eel-tailed Catfish) is a robust, hardy bottom-dweller with a distinctive eel-like tail and a calm, steady demeanour. Growing large and long-lived, it's best suited to big tanks housing similarly sized Australian or native species.
