I looked at teh tank earlier today and everything looked great..I've had the lighrts off for about 2 hours now and decided to play around with the flashlight looking at critters...but found long stringy threads instead?? They look exactly like "feelers" or the feeding tentancles that a galaxia or brain would but I have neither and the majority is coming from the rockwork and not on coral? It's limited to the left side of the tank-noticed it right after I put the koralia back into place on that side of the tank. It is on a feather duster, rockwork from, the sandbed upwards in multiple areas(doesn't appear to really have a beginning?) nor like it is coming from one place...can't really get a pic of it because they are so translucent but very long? Any ideas and should I try to remove them? turkey baster?? I have a beautiful sun coral, favia, trumpets and a toadstool in that area(and no, none appear to be coing from teh favia??) And parameters are in check
