Critter I.D please

[Pred24]

Hello everyone, I have these in my tank (apologies for the poor pictures) I was wondering what they are? They move around when the lights are out, they’re round so I’ve discounted limpets unless they come in round shapes too (I have limpets in my other tank hard to remove from the glass) these come away pretty easily when scraped off. Thanks

Looks alot like Nerite eggs. Do u happen to have any Nerite Snails. Or perhaps if you didnt introduce any, check if there’s any that could be hitchhikers if you bought any live rocks.

Looks like u even have one of the eggs crushed. Only the outline of the egg is left.

I was thinking eggs also, but OP says they move around at night…

I considered that too but the picture is telling me otherwise. Its way too similar to Nerites eggs. Perhaps OP should take a picture again at the same spot to see if the directions of the unknown critter moves.

I do have some nerite’s in there I’ll see if they move around, I do have snails roughly the same size which I’m presuming they’re collonista snails but I’ll look again tonight..

thank you everyone
