Tramatic Zoa Experience Resulting in Color Advancment?

[Zoaelite]

I'm just wondering if anyone has ever experienced this? I had a regular brown colored Zoo that had grown on a 2 inch rock, I also have a pesky Pistol Shrimp that took that rock into the deep abyss of its lair. Two months later I completely revamped the tank and found the rock. Too my surprise the Zoo's had grown and changed color on me! There in my propagation tank right now before I introduce them to the JBJ's 150W Metal halide. Anyone ever experienced this?
