When i was adding a new live rock in my tank i saw it come out but it ran away real fast and tonight I finally saw him posted up in one of my live rocks. It has been over 2 weeks since i last saw him and my main concern is if this hairy crab is going to do some damage to my reef tank.

I'd appreciate any info or advice on these hitchhikers. It really looks very very similar to WITFULL's pic he posted. Here's the link of the pic that he posted on this thread:

Thanks for any help.I'm a newbie in this and so far i'm loving it but there is always something new i learn about my tank everyday and today it was this mysterious crab hiding in my live rock.
