Snails got stress during shipping please allow them acclimate and adjust to the new home before they can move around. Sometimes it take 24 hours and very rare it take 48 hours for them to recover and come to life. We would suggest you to acclimate the snail the same way as fish and doing drip acclimation. After acclimation, you should slowly drop the snail to the corner of the tank and trick your snail by feeding them at another corner with algae wafer, bloodworm, or invertebrate food should do the trick. Please let us know if the snail haven't move after 48 hours and we will be more than happy to process with the live arrival guarantee.
