Well, all turned out well for my CUC. I "jumped the gun" a little when I didn't see much movement right away and thought that I didn't acclimate them correctly. But, as we all know, snails are slow. After about 2 days they all distributed themselves around the tank. A few are still in the same position I initially put them in. I figure I give them a few more days and if I don't see any movement should I remove them from the tank? If they did not survive will leaving them in the tank affect anything?
Again, thanks for all your responses. This forum is the best!!!
