Zoa dieing, anything I can do?

[Alvin414]

Things happened after I left home for one month (it was very urgent, sorry for all the residents in my tank). My friends helped me refilled RO water but no water change. Had set autofeeder but not worked quite well because of the net cover blocked the flakes.
The result was
1. I lost one green morph. It was bleached so I discard it, I now very regret that because after researching I notice that it has the possibility to recover.
2. My Midas blenny got missing.
3. My Zoa turned brown, smaller and fading away I think.

It will close when I touch it so I believe it has not completely died off.

I have put it in low light medium flow area for 2 weeks I think, but It does not show any sign of recovery.

I can not ID any Zoa pest or disease so far based on research. Realy need some help to save this guy.

Zoas can do that once in a while if a fish ticked them of or a light change or parameter swing I would just do water change put it in high flow to keep and detritus or debris off of it also leave it alone and resist temptation of touching it but I cant tell for sure but it seems to be alright just closed up.
