Stupid question. How do I get my open brain coral to stay put. Almost once a week I have to move it. I dig a small hole in my substrate and place it In just to try and keep it in place. It then puffs up so much it essentially lifts itself out and always makes a slow move until it is pressing up on the front glass of the tank which is a place I would like it to stay away from. I can't imagine that it is doing this on purpose but it is very frustrating.
