I'm assuming these are what I think they are

[Mrs. PL-Reef]

but I figured I'd check here anyway, better safe then sorry... I think my snails had a little fun last night after we lost power, these are everywhere in my tank, on the glass, on the rocks, on my zoas... I know they're not nudi eggs as I have already fought that war, and considering that the snails were right next to them I'm assuming I'm about to have a new population of snails. Any one have an idea on the time frame for the eggs to hatch, or anything I can do to help them? Thanks.
Sorry the pictures aren't the best...

yep those are cerith eggs.

from what ive heard they are impossible to raise do to them having a prolonged planktonic developement stage.

mine have started to lay and havent stopped yet, been like a month or so now.
