Was it shipped OVERNITE? That is a huge part. I have had boxed show up wet, adn the corals be fine. Zoas especially should have no problem recovering from an overnite journey like that. Without pics or positive proof of death on delivery, I would never give that person a second thought other than they are unwilling to take responsibility for the risk at hand. Once you ship an item, we all know the carrier is not going to handle the item as well as we would like, and it is not our responsibility unless INDESPUTABLE EVIDENCE is given. Tough stuff for the buyer. They should have taken the time to do it right instead of accuse you.
