Are these snail eggs?

[WRXTerror]

I hope these are Trocus eggs, I found them scattered on my rock work the other day. I used a baster to suck most of them up, but I'm sure I missed some. I was worried that they may be eggs of an unwanted invader but they seem too large. My nassarius snails have laid eggs on the glass before, but they were smaller and almost a pink smudge on the glass. I also have an astrea snail, hermits, and a fire shrimp. Any help identifying would be a help and ease my worries. Thanks

I thought Nerites were freshwater snails? I dont have any of those, I do have narcissus snails. there eggs I've had before, looks like a pink smear on the glass or rocks.

Theres salty nerites.
Can you suck some up and put in a container for a clearer pic?
And im certain trochus broad cast spawn and dont lay eggs.
