Yes, please post water parameters. Where are they in your tank? How much flow? What lighting do you have? Did you check for zoa-eating nudis and sundial snails?

What kind of lights were they under at the store? You may consider lowering them to the sand right in front of the glass so you can get a good look. It's possible they aren't used to your MH's.

No it's the lights really. Zoas are pretty hardy. They will do fine on the sand under MH's but most place them on their rocks so they will spread.

relax and give them some time. i traded with someone once, and it took 3 weeks for them to open.

They won't starve for a few weeks. Just give them time to open.
Also, something that no one has mentioned yet... the phosphate of .25 is pretty high, you might be in the future experiencing cyanobacteria, as well as some hair algae and other problems that aren't as pretty either. Get your phosphate levels down!

I am experiencing similar issues with mine. I am currently in the process of upgrading my lighting but, for future referrence, what is a good method of lowering phosphates?

I use a phosphate remover... it is a white substance... I forget the name but your local fish store should know what you are talking about.....
