The Yellow Sabretooth Blenny has a single long-based dorsal fin. The mouth can be opened very wide to expose a pair of large curved canines at the front of the lower jaw. The species is yellow above and white below. There are three dark stripes on the head and body.
The species may be a mimic of the venomous Lined Fangblenny Meiacanthus lineatus.

Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
