Crab good or bad?

[Nano]

found this little guy in an acro I bought today managed to get him out with a little shrimp convincing lol. is he good or bad? about 1cm across not one claw is larger the the other
not sure If i should banish it to the sump or put him back in the acro to hide lol
He is not hairy, but smooth, sharp claws, and a pinkish coloration
sorry the pictures not fabulous, still figuring out the dslr

Looks like an acro crab to me. I have lots of them, and they don't seem to bother anything. Just hang out in the acros.

Cool thanks guys, I shall call him Jim guardian of Acroporia p.s. I know its acropora that just sounded better

Sweet find!

I like to discover little critters :-) your lucky.

I was gonna toss him in the sump but he looks much happier in the acro lol

this is his "Crib"
Green Acro with purple tips and green Polyps
can quite get the color for what it is, but the frag is about 4-5" tall and 3" wide and 5-6" long so its more of a small colony a good score for $60 IMO
