After looking all over the net and trying to find Assassin Snails that were priced good with shipping plus a guaranteeing them I had no luck. I called a animal/fish store in my area that I have had very good luck with and that guarantee their fish for 2 weeks they had not ever carried them or seen them but have special ordered me some at a good price no shipping and a full guarantee so excited. My pest snails are having a population explosion it's like they know their months/years are numbered ( I have to many to even guess how many)
