Hi! OK I have this Lime Green Neon Algae growing on my base rock, I have examined it closely and there are NO hairs sprouting from it. It looked more like it is encrusting the rock and is hard to remove! Even my turbo snails could not get it off:;dk I have heard that it can be a precursor to Coralline or that some times coralline starts green and then starts to grow purple or pink. I have also heard that there are green strains of coralline. What could it be? In person it looks almost florescent and neon colored! Any help would be greatly appreciated! Thanks!:;thx Here are some pictures!
