went to another state to visit daughter. found a couple nice peices of coral i wanted and then since it was a holiday weekend and gonna be three days before we came home I asked about that. the girl said no way would they survive 3 days in a bag. I asked about oxygen and she said they just closed the bag but coral wouldn't last but 4 or 5 "HOURS" in a bag before dying. I know better than that, but I skipped the buy this trip. I regularly buy one day to bring home the next night and haven't ever had trouble, but I didn't want to chance 3 days.. what is the common opinion here? corals ? live rock? what is considered a normal safe time frame for most of you?
