Help with snail ID

[exnisstech]

I'm sure I added these (2 in the tank) but I went through a period of adding CUC to 3 tanks and can't remember it all. I have two of these and they are about ping pong ball sized. What has brought them to my attention is that they are nocturnal. I never see them during the day and when I shine a light on them they retreat behind the rocks.

Thanks. Are yours nocturnal as well? I think I added these guys several months ago but forgot about them until was looking in the tank after lights out last night and saw them. They definatly do not like light and immediately start moving away from it when I shine it on them. They are actually pretty nice looking as snails go. Nice clean shells that would normally be covered in algae if they spent time under the lights like all the other snails.
