Shell no snail ?

[Emma_fish]

I have found that one of my snails is gone there is just a shell left ? My other snail is fine though anyone know what’s happened ?
Help would be appreciated

Possibly a shrimp or hermit crab, some snails can't right themselves and if they aren't turned over they will die and be eaten leaving just the shell

Ah it was behind my arch so I couldn’t see it to right it I will get snails that can right themselves in future

It usually isn't to much of an issue except for when you first put them in the tank, that being said I had to undo some of my rock work for a turbo who had fallen just yesterday
