what is wrong with those they dont want to open up?
parameters are as follows
PH = 7.8
Salinity = 1.23
Nitrate = 0
Nitrite = 0
Temp = 77
Calcium = 450
they are inthe tank now over a week.
The larger ones have been inthe tank longer they have opened before but since placing the others shut close? Are they being social with the others??
Could it be light? Though I read Zoas are not as light sensitive or am I wrong?
I have 2 36W T8 12000K and 1 blue reef T8 light
here are some pics

I'll take a stab at it. Zoas are funny, I have found that they tak a long time to adjust to your tank, once they feel comfortable then they are at their best.
Your lights I don't know if they are enough, some zoas like alot of bright light and others are fine with med light.
what size is your tank?

Get a magnifying glass and inspect them very carefully. You are looking for nudibranchs and their eggs. Here are some pics to guide you. They may be different colors as they take on the color of the zoas they are eating.

There are buffers you can buy to increase alkalinity. You need to test for it though first before adding anything. Buy a KH testing kit. Not the kind where it just gives you a range, but one that gives you the actual dKH number so you know how much buffer to add because you do not want to get carried away. 8-11 dKH is ideal for reef tank, but I am sure everyone has their own special number they try to hit. I use Kent marine superbuffer-dKH, but I used seachem before and that worked good too.

I would say it is your pH and lighting.. if you have only 72W of 12k.. you should have 3 watts per gallon and you said you have a 165 gallon? That is aobut 1/5 the light needed.

I'm going with not having enough light. you have regular florescent bulbs which will not support coral life. you need a light up grade badly
