So this algae grows like a leaf BUT it grows flat against the glass, rocks, frag racks, frag plugs. It will grow over at least zoas. I can usually peel it off. I do not have a picture of it in the tank. But I have a piece that I pulled off - it’s dried out. I don’t think my tangs eat it. Not sure if anything does. It’s greenish brown. So think leaf but growth is in a mat.
