I have had pretty good luck trying to steer my anemonies, they can be quite stubborn though. I lucked out with my RBTA as it moved to a sopt right out in front. My green BTA insists on being covered, most likly due to the fact that it has bleeched. You could wait until its settled and then move the rock it sits on the where you want, but it will most likey just move again. After a few tries it might stay put, but then again....
