Well, I moved 1500 miles with oscars, though they were only a few inches long. I put them in a large ice chest and kept them on the front seat of the U-haul truck. Ocationally I would blow air into the water, they kind of lay on their sides, I guess cause they can't see out, when I stopped at a hotel to sleep, just took them inside and hooked up a small pump to pump air in the water all night. Also, had a cat and dog, it was really fun packing in a litter box too, especially when hotel said "NO PETS" Just an idea!!
