Hey there. Im new in forum and not an expert in hoby. There is something like snake skin, may be a kind of mushroom covering my zoa rocks. I couldn't manage to identfy it. Can you help me to identify and if it is bad thing how can i get rid of it?

That's a tough one. Myself I would wait and watch because they are so unique and uncommon. Most don't last long term in the average system. However a few types can overcome a coral. If the Zoanthids are not closing or stressed I would wait.
