I have noticed a couple different frags of zoas that get a real concentrated amount of color. Almost fake/plastic looking since the colors got so bold. I have both multiple frags of a couple that look totaly different from each other and also I have seen it happen to another overtime. As in a couple of months. I do not know if this harms them in any way. The 2 notable ones are GreenBay packers and the flaming rainbows/mandarins. I think I have a pic of one to add but if not I will take them over the weekend and show the difference. Here are the GBP. The brighter ones have not reversed to normal either, they have been side by side for many months now.
