Anybody else's cyano fluorescent?

[damsels are not mean]

For years I had red cyano that would come and go in small patches. I never paid attention to it. Recently, I have seen this green stuff partially beat out the red for space and I am not sure why. It may have come in on a new frag. Anyways it looks green under the whites but under windex it turns red and with fritz glasses it appears to really glow. The glow is stronger on camera.

Cyano under certain light will be red, green, blue and even yellow. Skimmate and type of food fed will transition colors
