Guessing GSF genetics in there due to yellow pelvic, anal, caudal fins - but like Eric says could easily be a F2, F3, F4 fish with multiple parental species genetics present. I'm not too familiar with CNBG but have seen some with a yellowish color on fins, but not that pronounced in my super limited experience. Regardless it's a beautiful fish.
