Yes, at night they will exit. I'm pretty sure most snails are nocturnal, as mine never travel all that much during the day time, but at night the glass is covered by them.
Can you describe how you acclimated them? I was really surprised by the method Keys Critters recommended, and others may not be aware of their procedure.
I think mine are just "challenged" mentally. About 30% have moved on, the rest are all stuck together and no one is going to give an inch. I wound up, helping some of them out of their jar today.
As far as acclimation, I got this from Keyscritters about a day before they shipped:
All inverts are acclimated to 1.025 @ 78F.
We pack and ship inverts dry. Before you receive your shipment have a container ready with "old" salt water (this can be out of your current system) that is adjusted to 1.025 @ 78F and well aerated. That is a measure of specific gravity and the measurement is temperature dependent.
Float the bags in this water for aprox 15-20 min to adjust for temperature, then just open the bags, rinse in aged water, and release the inverts into the container.
Proceed with any other acclimation after that if your system is of a different specific gravity and temperature.
So I did a 5-gallon water change the night before the delivery and kept the changed 5 gallons. I adjusted the changed water to exactly 1.025 and left a powerhead in it over night, with the heater set at 78. When the package arrived, I took all the bags and floated them in the bucket and in the fuge. After about 15 minutes, I opened the snail bags and added water, then poured the water and snails into glass jars. Since my tank was barely off the 1.025 mark, I then put the jars in the tank. Apparently the astreas are so excited about their new real estate; they have claimed the jar as their home. I think they are having their own little snail survivor going on and only after a snail is voted off the jar, do they venture into the dangerous openness of the tank.
The crabs and stars were shipped in water and I followed the normal drip acclimation method for these guys.
