I'm not sure which site you order from, but I get mine from ***********.com, which has a 14 day (up to 30 day for their agricultured corals) guarantee, and are very good about it. Regardless from whom you received this shipment, they should have a CONTACT US link -- call or email them and ask what you want to ask.
Regarding the shipment condition... They should not arrive without water and air within the bag... Any I have received via fed ex standard are triple packaged, and - even when there is a small leak, it IS small...
Shipping and purchasing info aside, I have several zooanthids in my reef. Altho 1 (a yellow colony) opened quickly --- I lost several polyps because it was incorrectly positioned (re: light, water flow)... They are growing back quickly now! Other zoos I've gotten have taken days -- and some have taken WEEKS to begin opening. In fact, I have an ELEGANT MOON CORAL in there that took 2 weeks to perk up a bit (still working on it) and an ORANGE SPOT that after 3 weeks is only now opening up...
Good luck. (Keep me posted, I am still learning and experiencing!)
