Update, yes, it was the 200 snails for 20 bucks, well, I did the 100 for 18 or somethin. Actually got about 150, and maybe 10 didn't make it/empty shells. Now, I bought several nassarius snails from liveaquaria.com and these are not the same. These snails were larger and in a brown shell. Very health lookin but... they are getting eaten like crazy, hermits, peppermint shrimp, and even my small cow fish, weird, my white nassarius are way smaller and get left alone. At this rate the 150 will be eaten in a few days. Good snack.
