A couple months ago I got an anenomie for my 20L (against all your advise I know). It did fine for a few days, then it curled up it's tenticles and hid itself in the darkest part of the tank! Several times I had thought it was dead, but each time it moved into a small patch of light and recovered a little. Finally it attached to a hermit crab shell and got moved into the bright part of the tank again, and it's doing a lot better again... That was a little more than a week ago, and it already looks a LOT better. What I want to know is how do you get these things to attach to rocks. I want to get it anchored to something before I move all my livestock into my new 55 (as soon as it cycles, probaly a month from now.) I appreciate any advise, thanks.
