polarbear Posted January 10, 2010 Share Posted January 10, 2010 Is the white spong looking stuff that grows in the tank good or bad? Its growing under some of the rocks where there is not light. should i be worried? Quote Link to comment Share on other sites More sharing options...
muddybluewater Posted January 10, 2010 Share Posted January 10, 2010 Good. They are filter feeders Quote Link to comment Share on other sites More sharing options...
Derry Posted January 11, 2010 Share Posted January 11, 2010 It also looks pretty cool when it grows enough to protrude beyond the underside of the rock. There's very little true while in a tank, and I love the big patches of sponge that I have in mine. Quote Link to comment Share on other sites More sharing options...
