ID Please
 

I found this critter crawling on the liverock. It's the roundish slug-like thing to the right or the birdsnest frag. I tried to grab it and it started crawling at warp speed and hid in a crevice. It's about 1 inch long by less than 1/2 in wide. Can the ID gurus chime in please?

Your description sounds like stomatella snail...is it in your pics somewhere?

Yes, it's in the middle of the picture, to the right of the birdsnest frag. It's light grey/white. I don't know how to draw on the photos, or else I'd circle it....

I see it, that's a Stomatella snail. They reproduce in the aquarium and are good grazers. Peppermint shrimp will often decimate a population.

Thanks guys, you rock! That's why I love this site....
