Do not EVER leave water in the fish tank when moving it.
Put any live plants in a zip lock bag with some water in it. Or wrap in wet newspaper and place in a sealed plastic bag.
2-1/2 foot square styrafoam Shipping containers from fish shops are ideal - it is how fish are shipped. Ask your fish shop.
Also dumpster dive at fish/pet shops as many throw them out; they don't want to be bothered with providing to aquariusts.
If you don't use a fish shop plastic bag , be careful as some plastic bags for trash have anti-mold or anti-smell coatings that could be harmful to fish.
If you put much more air than water you are probably good for such a trip. Close the bag to avoid sloshing water out.
Probably best not to feed the fish for 48 hrs prior so as to not have fish poop foul the bag and reduce the oxygen.
When I shipped killies all over the USA/Hawaii I use "bag buddies" from Jungle labs to oxygenate the water.
But I ship killies in only a few ounces of water and LOTS of air in the bag - for about 3 days shipping time.
The insulated box is important to keep the fish from getting too hot or too cold.
Some people use airstones in a slightly open bag to allow re-oxigenation of the water. There are battery operated pumps
or some people use 12-volt invertors. I personally don't think such is necessary if your water to air ratio is about 1/8 or better.
