the other day I noticed that my new Rasta zoas had been closing its polyps. One closed then opened and then the other closed. Something is bothering them. Looks like 2 antenna swaying. The flow is all off in the video and you can see the antennas moving as if there is flow. They also hide when my cleaner shrimp passes by. I’ve already dipped it in reef dip twice, once when i bought them a few weeks ago and again right before I put them back and shot the video. Anyone have an idea what it is?
