Hi guys!! I need some information on the snails I just purchased from my local pet store. The tag said "mystery snails" but I'm a little confused on what exactly that means. Are mystery snails their own breed? Or are they LITERALLY mystery snails (as in unknown). I've compared them to pictures and taken my own (which i will attach) and the smaller one looks like an assassin snail and the striped one looks like a nerite/zebra (is that the same thing?) But I want to make sure my possible assassin won't kill my nerite. Thank yall!!!
