Crab hitchhiker in my premium rock order

[Gundy]

Can someone please identify this crab for me. It came in with my rock order from TBS and am not sure if it is safe for my tank. Thanks

It's a mithrax of some sort pics of the claws for better ID.
It's just as reef safe as an emerald crab so make your own judgment there.

Red Mithrax, I had one on my TBS order. It was hell on algae, but I would not trust it over the long haul.

I think it would be fine in the sump.
