Oh almost forgot..are these your first zoas? If so, be sure to pick up a pair of gloves...thin latex with no powder. Get several pairs...your vet can order them if you want. The reason is some zoas have a palytoxin that is very toxic. Not all have them, and I didn't learn about it after I handled my first ones. I had fragged them and dipped them without a clue. Had a bit of a metal taste in my mouth for a day or so. The gloves will just be a safety thing.
