Good morning everyone, there are some small blue spots growing on my rock the pictures aren't too clear so they look Grey. Any idea what they may be ?

Looks very new. How old is the tank? Do you have anything in there with coralline algae on it? It could be early stages of that, which is a good thing. But it will not just show up on its own, it must be introduced into the tank somehow.

I added a green star polyp frag and there is some coralline on the peice of rock it came on. The tank is 2 months old and going through the ugly stage.

Ahh, well it could be from that then. Good luck with the ugly stage, it can be a real bear. I would recommend getting some copepods! Lots of them. And feed them with phytoplankton every few days. They will help a great deal with the ugly phase if you get them in the tank early enough.

I did some research and I'm wondering if they are really small baby sponges. What do you guys think ?

Yeah microfauna in general, keep dosing them, at some point they will explode and you can kiss goodbye to the uglies!!

I have 2 scarlet hermits in my tank that really only come out at night and they ate almost all of the detritus on the rock.
