Bicolor Blenny. Goner?

[OCDP]

I haven't seen my Bicolor Blenny for a couple days now... kind of getting worried as to where he would be . Fed garlic and mysis to the tank yesterday, and still didn't come out. I even moved his rock, shook it, re-aquascaped it.. he didn't come out (dunno if he's even in there)

Paramaters are good, just did yet another water change yesterday.. everyone else is out and about happy and healthy.

Any ideas?
