We just recently discovered his Crab which we didn't add intentionally but seems to be pretty strong (my wife noticed it because he grabbed a feed tube thing we were using on some corals lower in the tank). He's a red / tannish in color and definitely has hairy legs. We haven't seen him fully out but he seems to be maybe the size of a nickel or so. We've also noticed since we found him, our female Manadrin is not to be found - the male mandarin and others (Midas blenny, helfrichi firefish, 2 clowns) however, seem to be fine thus far. Any ideas on what it is and how to remove it? I've tried using angled tongs a few times and we've also had the baited glass in there the past 2 nights but no luck.
