I bought a Acara cat that was about 7inches one time when I was about 4hrs from home and I still had to stop at a friends house on the way and drop him off all together he was in the bag for about 6hrs but I just had the guy at the petstore put him in a huge bag like the kind the get there feeders in and a ton of water I checked on him a few times and he was fine all the way home. If you got a descent sized rubbermaid tub and just made sure you freshened the water(dumped out old and filled with new from same spot your cathing your fish) then he or they,as long as your not trying to take to many, should make the ride just fine. If your still iffy on that idea put one of those battery operated airstones in the tub to. Good luck, Man I wish I could go fishing but its already to cold here.Oh well theres always next year.
