What is it, a Grammistes blenny? I've had mixed luck with them... apparently there are some CB ones, but I've not seen any. If he's grazing on the rock, I wouldn't worry too much - try some
Mysis shrimp and/or garlic in the food that might encourage him to eat.
Seachem has a new product called "Entice" that's supposed to be an appetite stimulant - it's banana oil or something. I've seen it/smelled it but haven't tried it... but it might be worth a try... at the very least it will do no harm. The purpose of the product is to initiate a feeding response... like I said I haven't tried it but just letting you know it's out there.
