My anemone was bought three days ago and he was seeming very happy albeit secluded. I figured I would move him to somewhere with similar conditions once he was happy and over the change in salinity and other levels. In the middle of the day I went to check on him and he was much smaller and his tentacles looked flat and a little less colored. From the beginning he was looking a little stressed as the color was slightly different but then it got better but now this. I have seen that they will sometimes deflate to expel stale water is that what this is?
