i have had my crocia 4"for about 9 months but it seems like the purpleish color is fadeing in color slightly.is this due to something.water parimeters are good.i have a 125t with it on the sand bed and am running 2-250-10k.any ideas folks?

how tall is the tank? with the crocea on the sand bed it may not be getting enough light.
