My bad, Neon yellow glowing off of a parrot... I assume dye.
In reality, its probably just your crazy camera, but the lighter color the parrot, (usually) means lower the quality.
I dont know the back-round of this fish, so I dont know what its purpose is, Usually breeders who breed light colored parrots, do so to make dying the fish easy (jellybeans). But this very well could be from some rouge parrot breeder out there perfecting breeding yellow parrots. Yellow is rather unlikely for parrots and its not the "desired" color per say, but colors may change as it grows.
