I wouldn't assume that the non-moving ceriths were dead. A lot of times those snails won't move at all for a couple days after shipping and then suddenly they wake up and are good to go. They seem to go into some sort of hibernation thing during shipping. Also, they intentionally ship them in basically no water because those types of snails can survive with just a bit of moisture for several days no problem. I've ordered from them at least 4 times and I've always had at least a 90% survival rate. Considering they give you so many extras, that's pretty good! And yeah mine were always shipped with almost no water and moist paper towels. KPA (another Florida company) ships their snails the same way, so its pretty normal.
