my starry blenny has made a new couch out of my green polyp leatger I've noticed some bald spots on the leather where he lays is this due to to the blenny laying on it and just irritating it or is the blenny eating it? I've noticed debri on the leather I can't tell if it's sand or chucks of the leather but I can blow it away and coral doesn't have any noticeable damage so I don't know
