I looked at a hole that i have in my live rock and noticed white vine looking structures. Just thought it was some growth that came on the live rock when i purchased it. I turned my power head off and noticed that when i did this about 5 blue colored feathers crawled out of the end of the tubes they were contained in. I also noticed when i ran the Magnetic Cleaner near them, they sunk quickly back into their tubes. There are 3 of them and they all do the same thing. I did not purchase these. They dont quite look like featherdusters i have seen in pictures they are very thin and again only have 4 or 5 feathers all in line. What are they? I was thinking maybe i got lucky and there were eggs on the live rock from the pet store
. If these are anything worth while, how much would they sell for in the pet store? Just wondering what these things are and how i got them or how i can take care of them if i need to as they are beautiful!
