Anyone know what this is?

Found this is the bag with pagoda coral I purchased. Anyone know what it is?

Looks like a stomatella snail. Harmless, interesting algae-eaters, technically part of your cleanup crew but too small to have much impact. Very fragile, so be careful not to crush it in moving it. I don't think I've seen pics of black ones before- nice find!

Nice!!! Stomatella snail indeed. Them thing's move fairly quick around an aquarium and they eat up good amounts of algae.
