Looks a little aggressive in the first video, no?

Looks like what is generically called a "gorilla" crab. Definitely bad. I've pulled several from my live rock. A larger one actually chopped off a tube coral polyp. Good luck.

Not positive, can't see eyes or claws but w/ the Hairy legs, I'm guessing gorilla crab, get it outta there.

Oh crap it does look like that. Thank you for the help!

Put it in a sump or 'fuge if at all possible, they're pretty cool but not at all good for your tank.
