I see a lot of coral websites offering a DOA guarantee. Many require you to email within 2 hours of arrival if something is dead. My question is, how do you know if they are dead and not just stressed out. I just received my first shipment of corals via the internet and here are some photos. 2 hours is not much time to dip, get in the tank and see if they open up. Some of these are looking pretty rough, but others are already showing polyp extension.
