In all honesty, those could be polyps of nightmare zoas...did they ever open or did they just melt away. What was the water temp when they arrived...were they still warm? I get the shakes when I think about shipping prized zoas and palys by ANY carrier, especially in this weather. I believe that in this kind of weather, we'd be better off shipping our zoas via the wet paper towel method, placed into a thermos container with a wrapped heat pack....you lose less heat via air than water, the zoas go into "protective" mode (IMO) thinking they have been exposed so they shut up tight and do fine. No slime in the water, no banging around in the container, the wet paper towels act like a big cushion. Looks like the seller is trying to meet you half way, if it really was 36 hours, I think it's fair. I have had some problems with one seller in the past, but I certainly wouldn't say he was being dishonest...sometimes things happen...when there's losses, it's hard to make either side completely happy.
I was lucky enough to win the Jan drawing for the frag pack from Elite Reefs and we have been in contact and I'd rather delay delivery considering the weather than risking some sweet zoas. Elite Reefs has been very understanding about this. We are dealing with live organisms here, every one responds differently to shipping conditions. Selling on line is a tough way to make a living. If both side give a little I'm sure you can work it out.
