Hairy Acro Crab
 

I suppose any hairy acropora crab means bad crab?

Yup ;)

just tell him to shave! lol
put him in your sump. or kill it

Why are the Hairy ones Bad? I thought acro crabs were mutulistic symbiots?

I had a hairy dude on one of my milles that I thought was cool. Kept him for a little bit. Then, I started to notice one of my mille branches getting white patches. Took a flash light too it one night and noticed the little bastard was eating my mille!! Instant banishment to the sump. All my other sps' (that aren't frags) have hairless acro crabs with no signs of wear or tear. In fact, the other guys do what they are supposed to be doing, I can see them cleaning up food bits that get stuck in the acro branches.

the little green/brown hairy guys with white eyes do eventually clear out patches of flesh on your acro.

Thanks everyone. The little guy is now out of the tank. He was hairy & had red eyes. I thought I had lost him because right after I typed the original post he disappeared in to the rock but he came back out to the same sps tonight so I managed to nab him.

I have had a white hairy guy with black claws from day 1. Haven't had the heart to kill him, I guess I'm a bit attached. Hasn't eaten any of my corals and he kinda keeps to himself.
