Correct booze, they are not treated by any means, par latter maybe a antibiotic for any potential bacterial infections. You set up all tanks the same, so they even look the the same. And the water in all of them comes from the same batch mix. I use to run 5 - 10 gal tanks. And before the first move make sure they are eating. You still have to wait the 4 wks for the display tank to rid itself of Ick before returning the fish. This method causes almost no stress to the fish brought about by hyposalinity, copper, FW dips, anti-malarial meds etc., or what ever. My display tanks never knew what the word "Ick" meant
