My mushrooms in "natural" lighting

[lokelani808]

Well, we actually had some sun here today, and it's rays came through the window and hit the saltwater tank nearby. I noticed a little rainbow apearing in my tank over my blue mushrooms, and thought i'd snap some pics before it disapeared. Check it out, true blue rainbow polyps !

That's pretty cool. Never seen a rainbow in a tank before. Nice pics
