Jewelled Blenny

Salarias fasciatus is typically olive to brown with dark bars and a large number of round or elongated white spots of different sizes. The blenny has many pale spots, dark streaks that run anteriorly, and several dark bands. It is a small fish, which reaches a maximum length of 14 centimetres (5.5 in) TL. It possesses no notch in its dorsal fin. The dorsal and anal fins are attached to the base of the caudal fin by a skin membrane. Adult males have elongated anterior rays on the anal fin. There are usually dark longitudinal lines on the front part of the body, and small bright blue spots with dark outlines along the rear part of the body.

The Salarias fasciatus lives in reefs at depths of 0–8 m (0–26 ft) from East Africa and the Red Sea to Samoa and the Islands of Micronesia. It is most often found on shallow reef flats that have heavy algae cover.
