This huge snail that i got from the lfs after just a day as disappeared, the shell alone was around 1 and half inch long, they told me it was a sand sifting tiger snail, can they live out of water is this a possibility its gone and done one or do they sit under the substrate days on end, can't see his little breather pipe think sticking up anywhere?
