Can anyone ID what I have here? I think someone mentioned digitate hydroids on the zoa…but what about the other stuff circled? And the stuff growing on the side of the rock? Thanks for any input. Just trying to get it under control before it goes south. I have a lettuce nudibranch (to help with potential hair algae and bubble algae) and a fringeback nudibranch (to potentially help with the hydroids) I wanted a lynx nudibranch but they seem to be impossible to find. Also going to do a lugol’s dip once the solution gets here, in case it is some kind of infection. Not sure if any of that is going to make a difference or not, but worth a shot.
