Black Slashed Golden Parrot Fish

I just bought a 3 inch Black Slashed Golden Parrot Fish from Somethingphisy.com.  They didn't provide much information about it, but said it was a "new strain" of parrot fish.  Has anyone come across this fish?  I received it, and it has an interesting black streak on both sides and a little of a black streak on its top fin.  The basic color of it is light peach.  If anybody has any other information of this so called "latest strain" of parrot fish, please write about it.

Also, I have a black parrot fish which, after owning it for about 8 months now, "still" hasn't changed colors.  It remains black most of the time.  Occasionally, it will look like a light peach color is trying to pop through, but then it goes back to being solid black again.  Do you think this parrot fish will ever change color, or will it always stay black?  I don't mind the black color.  He looks good next to the other bright orange and red parrot fish I have in the tank.
