Hi, After some id help again please! Along with my spotty nerite snails, I also got 50 or so of these Cardina at the weekend. The guy I got them from said they were Tigers, but the banded markings don't seem to be clear enough for me to be sure. The adults are bigger than cherries and snowballs at about 2" or so. Some have an unusual blue tinge to the body. Any ideas please? Thanks.
