I got a green bubble tip anemone from my LFS for 3 days now, and sometimes, when I wake up, the anemone is face down on the sand bed. I just pick it up and then place it on a rock again. It then extends is tentacles and is fully puffed up, but today... I noticed that the mouth is slightly gaping open, and its also swollen. Is this bad? How can I fix it if it is bad?
