That does look like him for sure.
I tried several times to catch him but he's very wary of anything that gets close. I can probably chase him into a small piece of live rock and then either fish him out or break the rock apart until he's exposed enough for a capture.
Would he be ok in a refugium? Or should I bring him back to the LFS? There's one store in my area that will take any creature back.
Here's a close up of the little fellow.
