Hi mvergas,

I am not sure exactly what it is but have had many of them and they are harmless algae eaters. I bet greenbean will jump in here, he loves this stuff.

It's a limpet. They're generally harmless grazers, but may occasionally nibble on sessile inverts like sponges, tunicates, and sometimes even corals. They usually don't do much damage though.
