I got this guy on Saturday from a fish store in Palm Bay, Florida. I believe he's a male from his sucker size. He's from Haiti, I think he may be O. Vulgaris. I will post better pics soon, but they're on my other camera. He is primarily brown with a white underside. He changes colors very quickly and changed either completely white or brown/purple with white streaks.

I've got a 92 gallon corner aquarium, all of the water tests have been good. There's 100lbs of live rock in the tank. The salinity is a bit low, but I'm raising it slowly. He was active upon first being in the tank, but since has picked a den and I haven't seen him do much but stick a tentacle out. There are some snails and crabs in the tank, along with four damsels that I assume he will eat. When should I be worried if he doesn't start eating? He's been in his den for about 40 hours now. I'm not sure if he's come out at night though.

Any thoughts would be appreciated!

Awww, really? Poor guy. I will get them out tonight then. He's probably afraid. The guy that sold him to me told me he would eat the damsels. I asked him a few times, too. He seemed quite sure. I'll post better pics soon.

All right, so I got the bastard damsels out finally. Holy crap.

I have tried to put a few crabs in front of his den, a snail, and some thawed frozen krill. He sticks his tentacles out and feels them, then pushes/blows them away. What should I try to feed him next?

Here's some more pics, had to convert them from RAW.

More to come, they will just take forever to convert.

Thawed frozen krill is about the only thing my mercs won't eat. What kind of crabs are you using? Some will eat hermits, some only fiddlers. Frozen or live mysids usually work well, as does cyclopeeze. Give your guy a couple of nights to settle in. He will be strictly nocturnal and easily lost in a 92 gallon tank! You can try using red lights at night to view him. Check Trapper's or Vary's logs (or their offspring) for more details on mercs.
