I was looking in the rocks today to see where a blue Chromis was hiding and noticed I have tons of little feather dusters that where not there before. I counted at least 12 or so in a 4 inch area and I have a lot of rock so there tons of them. Can they cause a problem if there gets to be to many or do I just have to feed my tank like crazy. They are only around 1/2 total height right now.
