Just got my first bimac

The little guy is acclimating right now. I can't believe how small he is, his arm span is only 2"-2.5". I have a couple hermits and a hitchhicker crab in the tank with him now but I am worried the crabs might be too big for him. The hitchhicker crab's shell is about 3/4" wide, is this too big for the little octo? Would small ghost shrimp be a better size for him?
Heh, yeah I know but I think the little guy will be worth it. I put two emerald crabs in this morning and now I can't find them, hopefully he is eating but I haven't seen him since he went in the tank.
