Emerald Crab

I don't have any experience with ric's so I don't know if this would work for you but with some of my other corals (leathers, zoas, etc) if I have trouble getting them to attach I toss a little sand or a shell or something on top of them (just enough to weigh them down) for a few days, then blow it off with an eyedropper or whatever.

My emerald crab is my favorite part of my tank, he's so much fun to watch. But if he ever pulls some crap like that, he's going for a time out! haha! Looks great on the rock though!
