Coral stopped opening

[MACHO]

Hey guys I have 2 sets of green star polyps and a gorgonian they have completely stopped opening i've had them for a while and i've only moved the gorgonian the gorgonian opens up when the lights are off but closes up when they lights turn on my green star polyps are only opening about half way and my other set of star polyps have stopped opening entirely every other coral looks to be doing fine help please. I’ve posted pics on the corals any help is appreciated all the corals we’re doing fine a month or so ago I keep doing water changes but my nitrates continue to go up I haven’t done anything different I feed the same amount I do water changes constantly.

GSP is almost impossible to kill so no worries about that. Looking at your other corals, I have the feeling it might be linked with your lighting. Those xenias are definitely not getting enough light and look to be reaching for it. Maybe try to put the closed corals a bit higher and see what that gives.
