It could also be the Meiacanthus ovalauensis, Meiacanthus oualanensis (not sure which spelling is correct) - Canary Fang blenny or Yellow Forktail blennie.
I my documentation, I have only 2 listed with the dark line coming from behind the eye, the Smith's blenny and the Forktail blenny, I would put my money on the Forktail.
Omnivore and likes to eat variety of chopped foods (meats & veggies). Medium maintenance fish and may act semi-aggressively toward other fish. Needs plenty of places to hide & swim, and grows to about 5".
The same is true for the Canary Fang blenny.
