I have Caulerpa in my fuge and I have what looks like a bunch of feather dusters groing on it. I also have a few hydroids so I know the differance and its noticable. These look like little feather dusters with tubes and theyre kinda purpleish/white and brown, could they be somthing else?. If they are feather dusters should I put them in my display?? Reason I ask is im getting rid of the Caulerpa and going to Chaeto soon.
