Slug?

[RevJDA]

I found this animal "grazing" on the live rock in my 24 gal nano tank. I'm wondering if anyone can identify it for me. It looks like a slug. Is it, or ist it a parasite. I have been watching it whenever it appears. Nothing seems to be harmed by it. Once in awhile it will "puff" out a milky substance into the tank. I'm assuming it's some type of waste.

Does it appear to have a flat (slightly curved) shell on top? It would probably be a stomatella snail then. If so, they are good grazers.

It may have a shell. If it does it is certainly not as hard as a snail shell. It does appear to be a grazer. Do you know where these snails are found in nature?

I found this site with more information on the stromatella varia.

The really cool part of these snails is that they bradcast spawn frequently in the aquarium. Free food for your inverts AND they eat algea. Im surprised they are not sold in pet stores!!!
