What are these?

[_sludgefactory]

I bought some cuc from reefcleaners.org and some of the nerite snails had these weird greyish white egg sacks on them. Now they are everywhere, not like under taking the tank. Just growing in many places, especially on the magnets of my koralias. Any ideas?

I've emailed then to see if they know what they are also. They don't seem invasive it anything. Just curious.

Snail eggs. Nerites.

I agree with^^. I don't know if they hatch. I've never seen any baby nerites or had any extras show up. Most likely eaten.
