I got it around 10 months ago. It was the size of my pinkie finger nail. It stayed that size for probably 6 months . The last few months it has really started to explode & color up. It has always been a light shade of orange. Never green.When did you get yours, I got one from him. He did tell me it was barely a splotch on a frag plug though. And again, I think I got over zealous with putting it up high in the tank to the point that it did whiten up quite a bit, still looked good at "night" when blues/violet LEDs hit it mind you, but during the day time a lot of color is missing... it is working it's way back though.
