What is this eggs from snails??

[Oiva]

Hey guys

Last week my nassarius snails laid some eggs on the Aquarium glass. I have 6 of them, and i have had them for the last two years. However they have always laid eggs on the aquarium glass, but nothing happens after that. They just started laying eggs after i upgraded to a large tank (about 3month ago)

This week, all my glass was covered in white spots, they move around on the glass. I also see that my hair algae is covered in white spots as well.

So my question is this. Are these Baby Nassarius snails?

And sorry for the bad pictures. I forgot my fancy cam at work.

Are those Copepods instead?

Hmm i have been dosing with live copepods 2-3 times a week for my mandarin. But they dont move or look like a copepod. + i have only fed a few pods. I think my two wrasses + the mandarin would keep the population in check.

Spirorbid worms perhaps? (harmless)

The snails have a pretty complex life cycle. Going from egg to several forms on larva, before settling back as a snail. Any other features?
