I discovered nudis on my Daisy Polyps and Im not sure whether to bother removing them or not, or even dip it in Coral RX. They are the same colour as the polyps, and the polyps does not seem to mind much, since they remain open even though the nudis crawl up them. My problem is whether or not the nudis will spread to other corals ( I have various zoas, button polyps, palys etc. in my tank) and harm them. Could this nudis only be limited to the Daisies? I discovered quite a few.
See picture below.
Thanks
