Distribution & Habitat
Melanotaenia susii is currently known only from Susi Creek. Susi Creek is located on the road from Sorong to Ajamaru, 12 km after the frontier post between Sorong and Sorong Selatan Regencies. Susi Creek is a karst resurgence of less than 3 metres width with a course of a few kilometres before disappearing in a subterranean outlet. The habitat locality consisted of clear, shallow and slow flowing water. The creek flows over limestone boulder and muddy bottom with many dead tree branches, and is bordered by dense forest. Physical water parameters at the collecting locality on May 2007 were: water temperature 26°C; pH 7.7; conductivity 330 µS.
