Hawkfish + arrow crab = trouble?

[leafyseadragon]

I have a longnose hawkfish and a chromis in my tank, and I'd like to add an arrow crab I saw at the LFS. I know longnose hawkfish may attack/eat hermit crabs and ornamental shrimp, but what about arrow crabs?

Am I giving the hawkfish a new tank mate, or dinner?

arrows are huge, i'd assume it would be fine but i have no idea at the end of the day

it's up the the hawk, but as leo mentioned, if you purchased a larger one, it might be ok.
