i agree with your decision. just make sure the pH and temp are the same from where the fish are to where you are going to dip them. the easiest way, imo, would be to drip aclimate them from the display tank water, then buffer and raise the temp of the fresh water they will be dipped in. once the fish are drip aclimated to the display tank conditions, dip them in the fresh water for about 10 minutes, then go directly into the display so they don't contact the shipping bag water again. good luck.
