Naw, that's a bad idea.

Get a rubbermaid tub and put tank water in it and the fish. Add the filter to the tub so it will run.
Place the lid loosely across the top so it will be a little dark in there, allowing them to settle down, discouraging jumpers.
This set up will be fine for a couple of hours.

Having the fish out will give you a great opportunity to do a deep substrate vac, or even change it out.

Fill the moved tank with dechlorinated water, adjust the temp and add decor. This will be like a 100% water change.
If your tank has regular large water changes, the params should be very close to the origional anyway.

Don't scrub the tank sides or decorations and for sure, don't clean the filter.

I wouldn't add the old tank water from the rubbermaid tub back in.
The fish were stressed and probably gave off some hormones and ammonia.

Put the filter on the tank and run it for a while. Add the fish and leave the light off and don't feed them until the next day.
When you do start feeding again, do it very very lightly and slowly build up to normal over a week's time.
Test the water for ammonia and nitrite spikes. Be ready to do water changes if you have them.

You'll be surprised how long it will take to move your tank, even if things go perfectly.

Actually, I'd do some good water changes, gravel vacs and a filter cleaning during sseveral weeks prior to moving the tank.
Then fast the fish for a day before the move.

I welcome anyone else with more/better advice for jmm197 to please chime in.
