I'm with ewest on the fish in the second photo, it shows both male and female characteristics.

The pinkish hue on some bluegills is sometimes referred to as grapefruit coloration by those who obsess over all things lepomid. Not that I know, and/or socialize with anyone who fits that description.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
