How long will corals live in a bag?

[Myka]

Most courier companies including air companies will not guarantee or insure any live packages. So the "claim" you will be making will be to the vendor. If the vendor doesn't have a live arrival guarantee you may be shyte out of luck. Talk to the vendor and ask the vendor what s/he wants you to do - accept the order when it arrives or refuse it.

Having said that though, I have seen corals survive for 5 days in boxes/bags provided the box has stayed at an acceptable temperature for that length of time. Corals are much hardier than fish in that respect.
