Florescent orange algae

[tazdvl]

I would post a pic but don't have camera, you have to just trust me on this one I have a small 1/4 inch diameter piece of coralline algae on my heater, I knew they grew in a spectrum of colors but didn't know I had an international orange wearing one . Just wondering if anyone else has ever seen this. Now that I'm typing this I remember a tiny spot this color along time ago in this tank, thought it was just a speck of florescent paint from some cheesy fake coral rock I put in tank. But this is alive and growing on my heater.

Usually coralline when it grows will glow orange under the blue actinics or when you scrape it

My red-pink coralline will do this when I run it over with the cleaning magnet or when my tuxedo urchin snacks on it also when it grows
