Round white flat worms or sponge?

[JFinlay]

Hello! Looked thru the common hitchhiker page and can’t find anything on what these might be, possibly sponge? They’re just small round flat white blobs, there’s a bunch more than I took pics of on the backside of the rock. Probably 20-30, not sure what they are and would just like an ID. Tank is 3 months old

Okay. My are a more translucent. I asked about them yesterday and was told they were Nerite snail eggs.

Interesting, that would make sense I do have 10 Nerite snails and whatever they are doesn’t seem to move at all, just multiplying
