I have been having this star polyp coral in my tank for six months now and it has been opening every day since I purchased it. All of the sudden it closed itself up for a few days and will not open. I haven't changed anything I've been doing, so I wanted to see what others have to say about this type of coral not opening. I recently bought a sea hare although it shouldn't have caused the issue. Maybe the past water change stressed it out. All of my other corals (lps
, soft corals, etc.) are fine. If anyone has any suggestions on why it is not opening, I'd greatly appreciate them. I am very concerned for my coral because it has been three days closed now.
