I just noticed this beast in my tank. It looks kind of like a slug and has a few long hairs on it's back.
Any ideas as to what it could be?

If you look closely, you'll probably see that has a shell on its back. It looks like a stomatella varia to me which is a common (and good) hitchiker. http/www.reefcorner.com/SpecimenSheets/s...tella_varia.htm
