The swirly things eithereggs or babies snails.

But you have a noticeable flat worm on your glass too.

Its a google photo because my camera wont focus on that small of an object. So no flat worm, just the swirls. How likely are they to hatch? I was going to buy a new batch of snails to help with the hair algae I'm getting, but if they're just gonna repopulate themselves then why pay. lol.
