green moss on rocks

[kefbmm]

Tank set up now for 1 year and now growing green moss on rocks. It's not hair algae or cyano. Is this bad?

Sounds like some sort of turf algae? If it doesn't take advantage and screw up the whole tank and you think it looks nice, leave it be.

Thanks! But if it takes over the rock, what would eat it?
