These were found in my overflow. They occassionally show up on the glass but are very difficult to photograph. They are clear with small white flecks, and are hard. I've never quite known what species of snail they are, but they're prolific breeders and the babies survive.
they may nerite, i have ceriths in my tank and their eggs look like strings of white beads no clear part to them at all. i just wish mine wound survive long enough to hatch. they breed like crazy but nothing ever hatches, can't figure out who's eating them the shrimp or the fish.
