Crab Id?

[vertwake]

Just caught this hitchhiker in my new tank.

Anyone know if it is a good or bad crab? Seems like he is a mythrax based on some other pictures I've seen, but am unsure due to the claws... Caught him picking stuff off one of my rocks.

I can't really tell in the pic. Are the claws rounded or pointed -- as in weapons? If rounded, they tend to be more on the safe side, but nothing is guaranteed; I've had emerald crabs munch on my SPS.

The claws are kind of rounded. Look more like ET fingers.

+2 for mithrax. After reading a couple of posts it appears there are mixed reviews on them.
