I noticed a little while ago that thses silverish tenticle looking things starting growing on my liverock..they now look orange and my 2 osc clownfish are now all over them..cleaning them and fertelizing them i guess..any advice or insight would be greatly appreciated...i really dont want to lose the fry..I have a domino demsel, sea urchin,bi-colour blenny and a reef lobster also in the tank, as well as button polyps and cabbage leather coral ...do any of these pose any threat to the fry?
