Storage containers all the way. I brought my fish from Houston to north Louisiana using rubbermaids and battery pumps. Got em cheap online too. Rubbermaids I got a goodwill for a dollar each. You could put 10 to 15 fish in something at least 20 gallons and an air pump. I imagine you can only move two containers at a time unless you have a taco van so you could use a standard pump at the old home and another at the new home with some valves for diffusion to all containers. All you would need is enough air for 4 containers on each pump for here and there (8) and then 2 battery pumps for transit. If it's cheaper, rig a bilge pump from the outdoor section of walmart to you power supply (12v - cigarette lighter wiring) and just point it so it splashes water. Might make a mess but walmart will take them back when you're done. lol
