My LFS just moved their entire store (over 60 Tanks) to a new location. They individually bagged every frag/colony and filled Rubbermaid Flat Containers (like 36x36x10") half way with tank water (to keep the vibrations to a minimum) and floated the bags in each one... stacked the containers and then transported them in an empty van and just maintained the air temp inside the van with the A/C to around 75'F ... Some of their corals stayed in a bag for 5-6 hours before being replaced in the new (cycled) systems at the current location.
I inquired about the fish, and they said they used the same rubbermaids, filled with tank water, and transported them as is. They said no more than 6 Fish per container to guarantee oxygen levels... They lost no fish, but a handful of their corals bleached from the move. overall they maintained 95% of everything they moved without loss.
There are a couple other posts about big moves over long distances in the forum that are recent. KeyWord search it and they should pop up to see what responses were in those threads as well.
One way to think about it, is how all the specimens and fish from the wild make it to the suppliers we eventually get our stuff from. Some of those shipments are probably close to 12 hours, in a bag in a box. no environmental stability etc... They are fairly resilient to short-term moves I would imagine considering how many make it to our shores from the other side of the world.
