Just set the fish tank in the refrigerator and knock a couple of holes in the side for piping and the fish would be fine. Just be sure to go thru the side and not the back with the piping and drill from the OUTSIDE in. Less chance of hitting a Freon tube that way.
Oh…and it is a good idea NOT to indulge in alcohol before or during this “experiment” :drinking:

Hindsight IS 20/20 :puke:
