I have these wonderful red plants on 2 of my rocks that have been growing nicely for the past 6 months. About 2 months after I put the rocks in my tank I noticed some of them looked like they were florescent, It lasted a week or so then the glow slowly left them. Now , they are starting to become florescent again and I want to understand what triggers the glowing? they look really great when I just
have the blue light on.
