He came in with another one about his size in an order of blue legged hermits at my lfs but they wasn't sure on what he was.

he is in a shell that's about 2" long to give you am idea of its size.

It's a Dardanus guttatus (AKA blue kneed hermit) which definitely are NOT reef safe, and for that matter, they're pretty destructive in general. They grow quite large (I had one the size of a small softball).
