I have 2 colt corals. I got both at the same time. One attached to a rock within a few days, and is open all the time. the other will not attach, and never fully opens. It is not all the way shriveled, just not spread out. Does anyone have any suggestions on how I can get it to attach, and open? Both are in the same tank. All water parameters are good.
