When I did my upgrade I switched position of all of my live rock (obvioously). When that happened, all the feather dusters that were growing on the unexposed portions of the rock became exposed. It seems like they like the dark spots.... no? I've been wondering the same thing... how do I get rid of these things? If they get any worse, I'm going to take action.... for now, I'm just hoping that they stay as is.
Copperband butterflies... reef safe? really?
