How and how long did you acclimatize the shrimp?
I doubt the hermits killed the shrimp. However hermit crabs are predators and will kill and eat all the tiny beneficial critters in your tank, rock and sand which is the reason why they are not recommended for reef tanks. It is ok to have a couple as they are interesting to watch.
