Hi Everyone! I'm hoping someone can help. Over the past few weeks I've noticed the brown colored growth surrounding my Favia but I'm not sure what it could be. At first I thought it might be some sort of algae but now I have my doubts. It started to spread onto another rock that the coral was leaning against and I don't want it to get too out of control if it's something that needs to go. It's possible that it's nothing to worry about but I wanted to get other opinions.
I've attached a pic. Any ideas??
Thank you!
