What's up with my Arrow Crab?

[cujo97]

I've had my Arrow Crab for 1 month and for the past 2 days he's been staying in one spot almost all of the time. It looks like he's dead, but then when a fish approaches him he'll move a little. He also hasn't been as active when I feed them as he was when I first got him.
It's bascially a fish only setup, 75gal. pleanty of room, 2 clowns, 1 coral beauty, 1 royal gramma.
Any help and information is appreaciated!

Arrow crabs are very unpredictible in my opinion.Mine is sometimes got every claw and its mouth full of food,then the next day he just sits there.Maybe this is normal.How long has it been doing this?Is it eating?
