Coral banded shrimp ~vs~ Arrow crab

So....what is the life expectancy of an Arrow crab inhabiting the same aquarium as a Coral Banded shrimp? I'm not trying to run some kind of squirrelly fight club or nothing, but over the past couple weeks, I have noticed that my Arrow crab is missing appendages. This morning he had 4 legs and a (9-10 hrs later) he's down to 3 legs. The only thing I figure to be messing with him is that shrimp. Anyone ever seen something like that?

On a separate note, I did also lose my long tentacle nem and I'm beginning to think ole shrimpy is the culprit. I did notice my peppermint shrimp poking around his foot before he disappeared. Thoughts??

How big is your tank? That might be the problem right there. If they're constantly bumping into each other there's bound to be a problem.
