Small, white circles at the top of my tank?

Hello everyone! A few days ago, 3-4 small white circles seemed to form at the surface of my tank. Upon removal, they felt quite hard. Today, one more appeared and I’m wondering what it might be. The only things in my tank are Opae Ula, some MTS, macroalgae and a limestone rock. Any possible insight as well as if this should be a concern would be greatly appreciated!

That's what I thought at first, however many websites seem to claim that MTS do not lay eggs - any other idea what it may be? The shrimp do not seem to be bothered by it from what I can tell. Thank you!
