And acclimating..... whatever, I have temp acclimated 4 nems, with no drip, just add them to the tank afterwards. The problem with nems is they are very sensitive to ammonia spikes, as soon as you open the bag the ammonia will spike because of the added outside air. Ammonia levels will kill your nems. I have found a fast introduction to the tank is much better than them sitting in their own ammonia for an hour during a drip.
If you order online I would not drip them, I tried to drip my first BTA from LA and it died that day, the second one I got from them looked bad So I temp acclimated and put it right in the tank, the next morning it was doing fine and is still in my tank.
