small white dots not Spirobid Worms

[vayapues]

Working on my... I don't know... fifth tank maybe.
I have done this hobby now for 11 or 12 years.
In a new tank, (about 1 year old) I am getting a lot of small greenish-white dots spreading on the LR. These dots are about the same size as Spirobid worms, but they are not spiral in shape. They do not seem to like the glass at all. Not one of them is attached to the glass. However, they are spreading all over my LR.
Basically, they are tiny, mostly white, with just a hint of green, circular, flat. I would guess green coraline except that they never get any larger... just spread.
Any thoughts on ID?
thanks everyone!!

Do they look like this? maybe snail eggs

That is exactly how they look. Those are snail eggs?

Great tip Meowzer! Odd that I have not had them in a tank before, but then again, in this tank I have my entire CUC as snails. I purchased several different types that I had not used before. Generally I only use a handful of snails, and then several other creatures in my CUCs.
Thanks for the lead.
