Did my snail reproduce?

I'm fairly certain the bladder snail who hitched a rid on my plants from the LFS did not reproduce. I am still curious as to what these particles are. They did not appear until the snail climbed to the top of my glass canopy directly under my LED fixture. I read that snails lay eggs in warm moist spots. Well these particles are in a small pool of condensation under the led (which gives off a warm radiation). The snail also resides there constantly. Can anyone identify these? I am just trying to be safe because they might just be food particles...



Thanks
