Hi, my tank is about 6 months old and I have 5 “colonies” of zoas as well as a piece of Hollywood stunner chalice and a GSP. They were all doing great until, fully open great colors, new polyps, etc until about a month ago. Three of the colonies are still great along with the GSP but the Hollywood stunner changed colors, a few polyps were closed and now on 3 of the colonies they are all closed. They are all about 3” from the bottom of the tank on the live rock, they get good light and I feed them once a week. Any thoughts or suggestions? They are now all glued in place because I moved them around until I found the sweet spot but now that spot might not be so sweet...

Sorry, forgot to add. Tank parameters as of last week:
Ammonia - 0ppm
Nitrates - 5ppm
Specific gravity - 1.025
Phospates - 2ppm
Ph - 7.86
Salinity - 10.2 dkh
Calcium - 470
Mg - 1170
Temp - 78.4
It’s a 20g long tank with a HOB carbon filter & very small skimmer. I also have a small Koralia powerhead, I believe the smallest they make, 250?
