Cool on the zoas, Sherri.
Re shipping... the way I've done it is to put the zoas on a scrap of styrofoam and wrap with a layer of paper towel secured with rubber bands. Use a towel that doesn't fall apart when wet.
Dampen the towel with some tank water, and stick that inside a plastic bag. Splash some water in the bag too, and close it all up with a large volume of air.
The water inside the bag equilibrates with its vapor, so the coral doesn't dry out. The thin layer of water on the coral facilitates gas exchange with the large volume of air in the bag.
