shamefaced crab

[windeindoiel]

I just bought one of these, he's about 2.5 inches wide. I was just wondering if anyone has had any experience with these and more importantly, what should I be feeding him? He seems to have acclimated well and after a few days is scuttling all over the front of the tank (which is nice, he stays in view). I'm worried he isn't getting any food though, anyone ever kept these guys before?
