I have had 2 snails just die and be gone this last week, The shells are still there but they are not. Do they leave the shell and look for another and get attacked and eaten in the process? 1 is an Astrea and the other is a Turbo. I found the astrea upside down one day at the bottom of the tank and had a HC on top of it but when I pulled it out the snail was not there. The Turbo I found upside down this morning before I left for work and 2 HC nearby it but didn't see the snail in it either. I will remove it when I get home. Any ideas or somebody have this same issue before?
Thanks!
Thanks!
