if your moving to a diff city id test the water fist and see if its the same as where you live now. also move the fish last. to make it as fast as possible. use rubber made containers or plastic food safe container. the water isnt the important part of your aquarium(s) DONT let the filters dry out. empty out everything from the aquariums even substrate. this will make it easier to carry and also prevent damaging the tank itself from uneven weight causing it to break. other then that there isnt much to moving them.
