I have never seen this anywhere and can't find it on the Internet. It has grown on a rock pretty much in the dark has arms that look like individual feathers. Does not retract when touched. Deep Blue in color with a dark green/blue on the underside. Really kind of pretty just don't know if it is bad for the tank.http://img.tapatalk.com/d/13/12/24/zu7ahe8u.jpghttp://img.tapatalk.com/d/13/12/24/e8aqy8um.jpghttp://img.tapatalk.com/d/13/12/24/ute4u6e6.jpg

Could it be a feather starfish?

2nd feather starfish, I've seen them in red but not blue. Other than color it's identical

I think scutterborn recently found one in his tank that just appeared out of the blue.
