My Zoa looks unhappy

[HydroJ]

The red one are growing out on bottom but the top part has some degree of recession. The green one keeps not fully open. Also it looks like some kind worms living under its coat, I dipped the coral with coral dip twice can’t kill them.
It has been like this for 2 months.
The water: ph-8 kh-8 Ca:380 salinity:1.022
Ammonia and nitrate are not detected—pretty low
Light: nicrew 30w (80% intensity)
Thank you very much!

I'm no expert but salinity is a little low . Post more tank information. How old is the tank ? You need some nitrate and a little phosphate in the water column.

About 6 month, I did feed a lot, both powdered food and frozen fish food. I almost feed every day, I do not know why the nutrients are so low.

Maybe lower the light a little and bring salinity up . Mine close if they get to much flow . Like I said tho I'm no expert.

Cut back on water changes for a bit if you have 0 phosphate and nitrate. And feed more if you can . You need some nutrients in there .

I did all of that, because I read about zoa like some what “dirty” water. The red one start grow out a lot, but the green one still not fully open… I will try to bring salinity up a bit.
