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.
