who laid these eggs?

So I haven't gotten any responses on the other forum so I will post here. Just wondering if these are in fact eggs and what could have laid them. I only have LR and haven't added any snails or other inverts.

Thanks!

It looks like some kind of sponge?

I was thinking tunicates.

It does look more like tunicates now that you mention it. Thanks!
