Use the tuberware containers as mentioned. Go to your LFS and get the large shipping bags that they get when they get shipments in. Line your tuberware containers with these so that it hangs over the edges, then when you put the lids on it creates a seal so there is no splashing and you don't get water all over the place when you start and stop. Drill or melt a hole in the lid large enough for a air hose to fit through, and put an air stone in there. Thats more than enough for the trip you are making. AmmoLock and StressCoat are some good ideas, also adding a few drops of clove oil to calm the fish down another suggestion.
I've moved fish this way from Washington to Nebraska, and from Mississippi to Missouri. It works. Large fish, small fish, its tried and true. Just don't over crowd and you're golden.
I just don't trust myself since last time I did this 14 fish died, some fish was at 7-8in, I want to individual package the bigger fish separately and then the smaller fish 2 per bag. Better safe then sorry.
