Not attached to the glass and don't move.
We do have two Nerites......a Black Mystery and a Mixed one. I looked online for pictures of Nerite Snail eggs and the white spots look pretty much like the pictures, so I guess we have some Nerite Snail eggs. The tank isn't covered with them, but there are quite a few. Will have to wait until they hatch, if they hatch, and then take them out with the baster I use for the tank. I can't get the eggs, if that's truly what they are, out with the baster bc they appear to stick to the gravel and some of the plants.
We had a snail outbreak a few months ago, but I didn't see any white spots like these. Just one day, tiny snails started showing up in the tank. I use a baster then to take them out. Believe or not, I got all 18 of them out! I'm retired, so I had the time to get each one that I'd see.
We did get the Mixed Nerite a few weeks ago, so I suppose that is the one who done it. Anyway, I have a Tiger and Zebra Nerite Snails coming to me shortly. This Black Mystery and Mixed one just aren't cleaning the plant leaves that fast.

If they move they are limpets, a pest snail.
