White circles on back wall glass??

[DothanReefer]

What are these? Noticed a couple days ago, now there are a couple more!? Do I need to remove it? What is it?

preliminary research suggests nerite eggs or some kind of worm egg...I have no idea.

Those Nerite snails are your culprits. Those are the eggs from them and be prepared to have a lot more. Harmless of course but they lay a bunch.

I have 4 Nerites. 70g display with 30g sump. Only 2 clowns and some coral so far. Should I remove them?
