I have nassarius snails and they lay eggs on my glass every so often and it looks just like that,I've watched them do it.

I'm pretty sure the eggs are much tighter knit though.

My camera is not the best. But I too thought snail eggs and this has not moved all morning. Just want to ensure its nothing bad.

 

[Mikeamadio]

It would definitely have to be some kind of egg

 

[Trio91]

cerith snail eggs maybe? do you have any in your tank?

 

[MadReefer]

I have snails but don't recall which ones. LOL

Looking at a picture they appear to be Cerith snail eggs.

Thanks
