That's a really nice fish! Not going to comment on the color as the base color could be a lighter shade of anything and still look reddish with that pink light.
I would believe a seller claiming they fade later in life at 6" or so but not anything about fading skipping a generation etc. Either way awesome project. Very interested to see what color holds with the pearls in this cross!
I was attempting a super red syn type fish, hoping for the red and pinks of the bifa to pass down with the fading gene to achieve solid color, huge, vieja looking fish.
