Are They Mating???

[FishGeek]

They arent great pics (the camera focused more on the corals) but you can sort of tell. Are these snails mating???

This one you can sort of see the snails better but this is the one where they released.

I can't tell what's what in the pics, but I thought I had my only stomatella snail mating once. He went up to the tallest rock's peak and stood on his "tippy toes" if you can imagine a snail doing that. Next, he released a lot of tiny little green pelletized "stuff." Turns out it was a "concentrated waste material." Pretty cool if you ask me, but now after six months, I've noticed at least a couple more smaller stomatellas.
So your snails could be mating if there are two or they could be doing something else.
