Decorator Crab?

[John0]

I'm curious if this is a decorator crab or not, or if anyone can help me identify it. Also, what can I feed this guy? I've tried to feed him meaty foods but so
far he's not taking them. My tank is relatively new about 2 months some live rock but mostly base rock. I picked this guy up at a local tide pool hehe

It's a hermit crab

Not a decorator...it's a hermit...decorator's are large brown crabs that almost look like a tarantula, they're cool but not reef friendly, they "decorate" themselves with polyps and anything it can grab and put on itself or whatever sticks to it. Decorators are actually really cool we have one in a fish only tank at my work.
