Emerald crab attacking coral banded shrimp.

So yesterday I went buy my lfs and noticed they had a full grown coral banded shrimp listed for 10 dollars, me being the cheep reef keeper I am I bought it and put it in my DT. tonight right before lights out I was looking at the tank and I noticed my emerald crab(size of a quarter) that I've had without problems for months now had the shrimp by the antenna, before I could get the crab out to my sump it clipped about half of the antenna off(see picture) my question is, will it be ok?

Yes, but more fighting to come. Crabs and shrimp are not the best of friends.
