The bluestriped fangblenny has a flexible elongate body with typically dusky yellow/brown with white/pale blue stripes commencing either side of the eye and passing along the sides. It can be confused with the bluelined hulafish in Western Australia, and sometimes occurs in schools of that species, but the fangblennies’ tail is normal rather than elongated at the centre. This is the most common of several colourful fangblennies that live primarily in the tropics but are occasionally carried south by currents. They mimic cleaner wrasse by approaching large fish (and divers) as if to remove parasites. When close enough, they dart forward and remove a piece of flesh using two sharp fangs. Rapidly retreating to shelter often in old worm holes in reef the reef where they hide with heads poking out.
