Critter ID Please

I removed this from one of my Favias, and do not know what it is. It was hard to the touch and a bit slimy. Sorry for the rough pictures. Any help would be appreciated.

My guess would be a stomatella snail. They are harmless.

Stomatella snail, just algae eaters.

Yep, stomatella. Did it drop its tail when frightened?
