I was about to post the same thing except it was regarding my corky sea finger gorg. It has gotten really fluffy over the past month but when I feed the tank I tend to watch my fish more than I do my corals (even though I target feed everyone). About a week ago I happened to watch my corky as I was feeding and I noticed the polyps were almost pulsing as it grabbed food. The polyps looked like tiny hands clenching and unclenching. It was mesmerizing. My gsp was the same. I have to get a video of it.
