That is way too short of an acclimation!!!

I acclimate all critters at least 1 hour by bag method (remove water from
bag, add tank water to bag every 10 min.) and echinoderms and arthropods and
gastropods longer with drip acclimation.
Was that the acclimation instructions given by the shipper?

I purchased some astrea snails which were about 24 hours in transit. I
noticed that the shipping container was quite warm (90 degrees
estimate). It appears that most of the blue-legged hermits have
survived, but that the majority of snails have not moved after a brief
(15 min acclimation) and placement in tank. They are not moving, and
at best react very slowly and sluggishly if I touch the foot. It has
been about 18 hours since I placed them in the tank. Any thoughts on
anything I can do, should have done to keep them alive. Will they
survive or likely die. When I have ordered astrea previously, the
snails have appeared to recover after a overnight in the tank.
