Green legged hermit crab reef safe?

[Pdm2476]

Anyone have any experience with these?

 

[Calappidae]

Can you specify? There are numerous types of green legs but with different names.

Yellow tip hermit crab and green line hermit crab are what come to mind for me.

Those tiny blue-leg or red-leg crabs are safe. I don't know about anything with green legs, though...
I do know my LFS has a green hermit with a shell the size of a kiwi fruit. About 2" long, in other words.
