Reef safe crab???

[CD.Priest]

Hello again, I never bought anything other than the tiny blue leg crabs so I'm not sure how this guy got in there. He has become huge, well huge for what I've seen in tanks.... Can anyone identify what kind of crab it is? Is it reef safe? Just saw him eat a baby snail, they bread in my tank. The shell it's in us prob about 3-4" long. Oh, the snail it ate wasn't the one in the picture. Thanks for all the help.

Looks like a thin stripe hermit, I have a couple and they definitely seem to grow faster than my other hermits. I've had no trouble with him in my reef tank.

They are reef safe but grow pretty big. I have several in my tank.
