If you are transporting them in the air conditioned mini van in containers, I would not have a problem. We did the same when we moved from Mississippi back to Texas. We used a van with a/c and had the fish in containers with air pumps ran by an inverter. ALL fish survived and we had SW and FW. We had some FW Fancy Goldfish that we near 12" long and 2 Lionfish 12"+. I would have no problem recommending this way as the best way to transport the fish. Hope the move goes well for you, sorry you are having to leave the best place in the world.
