I had planned on putting in some snails in my pond once the algae started to grow and early last week I noticed I had quite a bit of algae on the rocks and such, so on Wednesday I placed an order for 20 Japanese trapdoor snails from an internet site. On Saturday, they arrived at my house. I was surprised at how little water was in the bag. In fact, there were only drops of water, with a damp folded up napkin in there. I don't know if that was bad or not, as I've never ordered anything that is alive off the internet before. However, I had assumed they would be in water, not by a damp cloth. Anyhow, they only sent me ten snails, despite me ordering twenty and the packing slip that came with it saying 20. I'm sure this was an honest mistake and I'll be calling tomorrow to clear that portion up. However, what was troublesome was that only 3 out of the 10 were definitely alive when I received them. Three of them were quite obviously dead when I got them (meat out of the shell dead), and four of them literally have not moved an inch since putting them in the pond two and half days ago. Their trapdoor is in place, but there has been absolutely no movement whatsoever. How long should I give them? I don't want them to rot in my pond while I try and figure out if they're alive or not. Are there any good ways of determining whether or not they're alive? I can't help but wonder if the shipping container was inadequate and contributed to their deaths. What do you guys think?
