Raise your salinity to 35-36.

2 months is pretty new. Allow aquarium to stabilize 6 months.

What is your ammonia, nitrite, nitrate levels? Ensure you are cycled.

What is your phosphate level?

Stretching zoas is a sign of not enough light, ensure 50 par for zoas.

Lastly zoas to me atleast are tricky sometimes. I have had many melt and die for no reason.

Check out the treads for help and I recommend youtube/google "BRS 52 WEEKS" Watch those videos.

Yes looks like part of the coral.

Your zoa will probably not like nitrate 0.
