Help with ID please

Starting seeing these about a month ago and need some help. Its not coralline. That I'm sure of. In the center of these dots there seems to be a yellowish yolk. I'm thinking snails, but I've never seened them move.

I try to keep the front clean but they seem to reappear. They are all over the tank.

In this pic on the lower left side is what usually is left over. Not sure if it was eaten or just hatched?

Do you have any nerite snails? I have one in my tank that puts those all over the tank. Just means the temp, PH and a few water parameter changes that happened make it a good time to spawn. :bunnies: Favorable drop in certain parameters during the night/day cycle cause them to lay more.

I think I did get some about 10 nerites a few months back. Are these eggs or are they baby snails that just dont move?

Heard they multiply quick too. I only have one and he is slowly stopping the egg laying.

Thanks for a the replies. After a little research this is what I found:

Nerite babies: Nerites have separate genders and engage in internal fertilisation. They have a complex reproductive system to achieve this, and to produce nutrition-packed eggs in protective capsules. The white circular egg capsules are sometimes seen in rock pools, under rocks and in moist crevices. Each egg capsule may have more than 30 eggs. These hatch into free-swimming larvae that only later settle down to develop into snails.

So each of those eggs are actually capsules with at least 30 eggs in them. :snail:
