I need help quick to save my sebae anemone. Tonight I came home and notice that my 1" frag rock with the sunny-d frags was missing. It was on top of a rock cave overlooking the anemone in the sand below. I looked everywhere and even took a few of the rocks out and could not locate the frag. I thought that maybe the sebae ate the rock, but there's no way right. Well, after looking for an hour, I pulled the sebae from the sand and sure enough in it's mouth, I could see the corner of the square rock. The anemone is only 4-5" when fully expanded. So the mouth is not big enough for me to pull the rock out. What do I do? Do I risk tearing the mouth and get this frag rock with the paly out?
