Algea id?

[magikof7]

I have this algea growing in my Fuge, I actually plucked it off of a Zoa frag I got and stuffed it into a little hole in the rubble a couple of months ago. It isn't very fast growing and doesnt seem to be spreading.
It is a Blue Green color and the Pods love it. I don't believe it is Calupera. (it is too feather like) any idea what it is and if I should keep it or kill it?

This first pic is more true to the color.
