Acro Crab?

[lachrimae]

Is this a good or bad hitchhiker? Not sure if it's the same as the "good" acropora crab:

I've noticed that there are some spots on the acro that look like they've been chomped on but it's hard to tell for sure. I don't want to rip this guy out of there and kill him if he's not the culprit.

Thanks,

Mark
