Zoas can be finicky sometimes, but also one of the hardiest corals out there. Remember that they are photosynthetic and not all zoas like the same amount of light. A lot of the "designer" zoas (thats what I call the high end ones) can be very picky when it comes to placement. I have had zoas that opened as soon as 20 mins after introduction and others that took 2 weeks. It really just depends . Maybe they don't like the flow. Just a couple options for you to look at.

Turn a flashlight on tonight and look to see if there are any little nudibranchs crawling on them. These pests are vicious and will target the higher end zoas. I have dealt with them before.
