No. I knew that and let them sit and continued acclimating until this morning. A few,5 or 6 of the Nass snails yesterday, but nothing this morning. Also the bottom plate, don't know what it is called, sitting wide open on all of them. When freshwater snails are found like that it means they are dead, at least that has been my experience with them. Most survived so I guess I am OK, and they are cleaning like crazy, I just hate for anything to die I guess. Have not heard any more from R2G, except that they will be issuing a store credit. Hopefully I will find out how much Monday. This was a learning experience for me as I have never ordered live critters before. Next time I will know what to expect.
