Dr Ron tips on how to acclimate snail if they're transported in bag full of water.
From RC...
" Remove them from the bag. Let them dry out in a cup or bowl for about 15 minutes. Then take them one by one, and place them in the tank at the water line with the aperture next to the wall. The animals will extend, fasten to the wall and move into the water of their own accord. In effect, they will self-acclimate. "
