ID this crab please

So I've spotted this guy several times. Each time I find him he is bigger. Up until tonight I was never really able to get a pic of him. He was out on the back of my rocks scrapping coraline off my overflow to eat. What the heck is he?

The pics are not the greatest as he was in a place that I couldn't get a good view of all of him, but hopefully someone has seen him before.

Mythrax crab. Reef safe.
His claws look cup shaped to me.

Maytrix crab. Reef safe.

Ummm mythrax? ;) I wouldn't be so sure... It's hard to tell!

I just looked that species up. All it shows are the Emerald crabs.

I'm leaning towards Xanthid crab of some kind.Not reef safe if it is one.

They look cup shaped to me also or at least flat and not pointy.

Well, he has been hiding in my Frogspawn every night, so he should be easy to get out. I just hate the idea of moving it though becasue it's so big.
