How far have you moved your aquarium? I once moved mine from NYC to Chicago in 2 days in the hatch of my Honda Civic. Everything made it! 800 miles! Tips: Coolers, double bag fish with extra water and air from an oxygen tank from your local fish store, wet towels on rocks to keep them damp, and try to bring at least some of original tank water if you can. Watch the temp in the car. May need heat packs.
