What is this growing on my rock

[NYAUX]

I have this algae of some sort growing on my rock , should I leave it or take them out ?

It just looks like normal green algae. My snails keep it in control in my tank

I think he's talking about the algae on the lower rock .

That algae looks kinda cool, not sure what kind it is but if it's not spreading like crazy I'd leave it just for looks.

Yes the round looking things I have some more on other rocks too..they look nice but i just don't want them to get out of hand , if its good fo rthe tank i'll leave them . Do you think an angel fish would eat them ?
