I was sitting at my desk and just happened to look back at my tank, well to my surprise there was this huge black crab leg sticking out from a crevice of a rock grabbing at fomr food on the rock. It was black colored with grey fuzzu hair, never got to see the rest of the crab, as soon as i spum arounf it jetted back in cover. Any ideas as to what kind it is, or how to draw it out to trap it. I switched to a predator tank about 3 months ago and had never seen this crab in the 3 years of reef keeping previous, but i always knew i had something in there, now i know, but what is it. Any help appreciated....it was ugle, **** ugly..... >_<
