To be clear - soft corals absolutely survive 2-3 days shipping. It is my preferred shipping option for any soft corals; overnight is a huge waste of money for these animals.Good eye...WILL Coral Typically survive TWO DAY shipping with insulation and heat pack etc?
In this case I’d be selling Frag packs like hardy Zoas (eagle eyes, Fire and Ice, etc) GSP, Armor of God, firework clove polyps. They aren’t high dollar so knowing folks want to bundle or buy high end which I don’t have much off I opted for the bundle attempt.
You use a 72 hour heat pack, so they stay warm the whole time. And winter is the best time for this -- its relatively easy to keep animals warm, but harder to keep them cool. (As a side note its funny how bad some shippers are at temp control. I've received corals in the summer that were packed with a *heat pack* instead of an ice pack. Needless to say they were all quite dead!)
I sometimes even order hard corals with 2 day shipping and have never had any major problems. I don't ship hard corals 2 day though, because there will be enough DOAs the refunds become a pain.
