Salarias sexfilum (commonly known as Spalding's Blenny) is a species of combtooth blenny found in the western central Pacific ocean, particularly the shallow fringing reefs and tide pools of Australia and Indonesia.

It has double vertical brown bands along its belly and a pink ocellus on its chest.

The dorsal fin extends gradually higher than the beginning of the posterior third of the soft portion, creating an arch that seems to be continuous with the caudal fin.

[5] This species is found in parts of Western Australia, Northern Territory, and a small fraction of Queensland, where it is found between Exmouth Gulf and Gulf of Carpentaria.

The blenny is also found commonly in Indonesia, particularly amongst the Lesser Sundra Islands and the Arafura sea.
