I found a snail or slug? that has a tiny shell sort of like a pinky fingernail on its back, the snail is no bigger than a dime and is a light color. It appeared to be grazing on my rocks but there is not much there to eat besides coralline algae but i dont think it was eating. I couldn't tell it had a shell until i touched it. any ideas? sorry no pics I can't seem to find the bugger.
