Name this macroalgae...

I've got this nice macroalgae growing on a piece of LR. Its a dark reddish color and seems to fluoresce blue under the actinics. You can see it in the foreground of this pic in front of the fish.

I want to say gracilliaris.

I was going to say Galaxaura, but I think rather, that it is Champia spp. Champia spp. is known for it's blue-green 'flourescence' underwater. There's a (bad) pic of it on this page:
