The cichlids are easier - 5 gallon buckets, with battery operated air pumps - KEEP THEM WARM, KEEP THEM WARM, KEEP THEM WARM - use bottles of hot water, blankets, keep the car itself warm, etc. DO NOT PUT THEM IN A TRAILER - they will die on the way (I learned this the hard way one time, on a SHORT move.)
The arowana and TSN - extra large styrofoam box, with XL trash bags - 5 or 6 inside each other, filled with a generous amount of water to minimize sloshing, and again, an air pump.
I have done this a few times with no deaths, other than the one and only mistake I made a long time ago, thinking a half hour would not make a difference.
