Tramatic Zoa Experience Resulting in Color Advancment?

[maxxxim]

Zoas do it all the time, well atleast IME. I've heard people getting some cool looking morphs just by spliting a colony, leaving one piece alone and moving the second one into a new location in the tank. I had a small colony change colour twice on me... 1st was when I brought it home from the store and then again when I upgraded tanks. It went from blue to pink to purple
