What are these things?

Hi all, can someone ID these green discs? They showed up a week or so ago. Three of them as far as I can tell. They haven’t moved. Are they harmful? Thanks

I’m not sure what they are - do you think you could get a close up pic of one under white light?

Looks like algae spores. Please post pics again under white lighting for positive i.d.

I did a water change today and the water level allowed me to take a close up, also they are hard, calciferous. Honestly they feel like a montipora. Not saying they are but that’s what they feel like

I'm not sure what it is, but montipora or another coral may not be a bad guess. The only other thing I can think of at the moment that it might be is a bryozoan such as the Alcyonidium sp. (the first specimen pictured) in the link below:

That looks very close! That's pretty neat. Biodiversity for the win
