Got this beauty about a week ago and have been admiring it ever since. From the moment I got it it has been open and large (about 5inches in diameter). Suddenly today all the polyps went in and it closed up. I wasn't too concerned at first until I noticed a few polyps on one side were hanging off. What could be causing this?
I did a water change yesterday (10%) and added some NTLABS Marine trace element replacer (the appropriate dosage) to the water. Could this be the problem? I also added some NTLABS Marine Parazoryne as I noticed white spot on one of my YellowTail Damsels. However this is supposed to be safe with corals.
It's a 55 gallon tank with live rock and sand, jewel protein skimmer, filter and the works, powerheads, etc.

I know the nitrate levels are high but I have been doing frequent small water changes and it's not changing. Any ideas? I don't think I'm over-feeding.
I have 2 YT Damsels and a Coral Beauty. Could this be the culprit? Or maybe my hermits? I also have a flowerpot that is doing fine. I just got this coral and love it when it's open and don't want to lose it. Is there a possibility it is molting? I read some toadstools do that...
It's usually much more open than it is now...
