Identification

[don12345]

Hello! Need help identifying. I’ve been a reefer for around a decade and have never seen this before. Maybe some of the more advanced reefers have come across this. Apologies if this is posted in the wrong area. The smaller white circles. Water Params normal, lots
of crabs and snails.

Looks like either nerite snail eggs OR sponge.
If uncomfortable , scrape off outside of tank and discard

I would have guessed sponge. Pure speculation.
