Couldn't resist getting yet another snail today. Probably shouldn't have, but I did. Got an Ivory Mystery this time. The snail collection is now 1 Blue Mystery 1 Ivory Mystery 2 Black Racer Nerites 1 Horned Zebra Nerite The Blue Mystery immediately checked out the new friend (pictured below). After that, the Ivory started exploring it's new home. I thought my Blue was big. The Ivory is HUGE!!! The last picture shows the difference between it (biggest snail) and the Horned Zebra Nerite (smallest snail).
