Aquarium Advice Regular
I saw this thing cruising around the rocks a couple of months ago but did not see it again until today when I was restructuring the rockwork. The first time I saw it, it was about the size of a dime. Since then, it has grown to about the size of a nickle. It mows through algae and moves reasonably fast. It has a conical shell and the only time I saw it on the glass, it looks like the underbelly is completely exposed.
