    Hello.

    Can someone help me identify what these stuff growing on the rocks are? and are they bad or beneficial to the tank? I attached the pictures. Are they safe to keep?

    Also my bristle worm disappear since last night. I never seen it anymore. Are they nocturnal? Should I expect there are more creatures hiding inside the rock?
