 Re: fish in Live Rock
If the rock is not supplying all of his nutritional needs and you're supplementing his diet you might be able to bait him into a trap. I've seen fish traps at the LFS that could easily fit into a 10 gal tank. Another thing you might try (just a theory of mine) would be to slowly lower the water level until he comes out of his hiding place and can't get back in, then pull the rock out. You could make a sort of fountain using a small power head to keep the rock wet without it being completely submerged.
I've also read that when all else fails some people have had good luck with a properly sized hook with the barb crimped or filed off. (catch and release)
Just make sure you have a new home ready and waiting for him when you do catch him
