I just drip acclimate anyways. Never had a problem. Just get a bucket, airline tube with a knot or two, then put the fish in there. You have an option of floating the bag first on the water for 10 minutes to equalize temp. I rinse the bag, though.
After two hours, the water is acclimated. You can either just drop it in or re-float the fish (put it in a ziplock bag and float it again). But I don't bother. I just drip acclimate, then scoop the fish out with a plastic cup, drain the water from the cup, then slide the specimen in the tank. No deaths so far.
We live and we learn
