I recently bought at a frag meet a nice piece of LR with 5-6 mushrooms on it. The day after adding it to my tank I noticed these guys. In case the picture does not help. The have ~5-8 leafs coming out of a very small tube. There are about 15-20 in a tight cluster. They are not changing in size and at night they disappear. Are they some type of tube worm/ flower duster. Thanks.

Some form of tube worm would be my guess, I think I tried to ID the same thing a couple of years ago and never got a definitive answer. Most likely they are harmless filter feeders that will do well with little or no intervention from you.
 
If the polyps are jagged as they appear in the pic, you might try googling Cornularia and see what you come up with.

Yep it is a species of Cornularia. From what I read they can form mats and are safe. Seem to be growing with only 80W NO, interesting. Thanks again.
