What is this? Small white squares?

[Afkomjorgen]

Noticed these after moving some rock work around this week. They’re very uniform and bright white or light blue.
May be nothing but I thought I’d ask

Snail eggs. What snails do you have in your tank?

Snail eggs. What snails do you have in your tank?

Oh boy. A bunch. Nassisarius, Cerinth, Astraea, a turbo, fighting conches, Nerite, periwinkles.

 

[Afkomjorgen]

If they were in a shadowed place have I messed them up by turning the rock over?

 

[EeyoreIsMySpiritAnimal]

My guess is nerite, but they'll become fish food.

Thanks that’s cool.
