No talent with cameras but it looks exactly like this: http://www.liveaquaria.com/product/prod_Display.cfm?pCatId=591 Black with bright blue spots. It's about 7-8 inches across and has been living quite happily & healty in my 90gal for about a month now. It's pretty cool in that it's out quite often and moves around. I got it from another fellow reefer when it outgrew his tank. Now I'm passing it along because I'm too lazy to keep up against the increased bioload. Pickup is at 08520 (bring your own bucket of saltwater). I'm giving him away for free but I wouldn't turn down a frag of something if you insist
You should have a decent sized tank and secure rockwork cause it does like to roam the tank and wedge itself behind the rockwork at night.
