I’m having a problem where in the morning my corals are fully out, big and extended specially my Duncans but I’ve started to notice that throughout the day they close up randomly, most of the it is when I go out and when I come back few of my corals are closed up and I have no clue why, all my water fine, I do have a cleaner shrimp and I’ve seen him close up my corals before, so all I can think off is that my cleaner shrimp is doing it. Does anyone have any ideas what it could be or do people think it could be the cleaner shrimp doing it thanks.
