Hermit Crab ID help

[Dano999]

I ordered a few Scarlet hermits and received one pictured below that does not appear to be a scarlet. From what research I was able to do it looks like a Laurent's Hermit Crab.

Can anyone confirm the ID and let me know if this hermit can be harmful to corals or other inhabitants? So far he is not very active and does not appear to be doing as well as the others.

Thanks

looks like a hairy red leg hermit to me... I forget if they are reef safe or not. I think they get big tho, from what i remember. They get to be large and predatory, but correct me if im wrong. (AKA i think they aren't reef safe)
