I received that photo last month (unlabeled at the time) and was asked about that fish... what a fish! I thought Centropyge bicolor/C. heraldi hybrid... I don't think it's a full xanthic bicolor, as I've seen many... this fish clearly has input from bicolor...dorsal and anal fins... lines on the body..., but the face, overall body morphology, and anal fin coloration appear to show heraldi... heraldi and bicolor are very closely related along with a few other species and share an overlapping range... so that's my postulation...
Joe Russo is a true fish nerd and knows his stuff... he should be commended for bringing fish like this to our side of the pond... It's not an easy business and he's worked hard to get where he is... way to go Joe...
