Thanks Al. I'm beginning to wonder if there are any absolutes when it comes to sexing young CNBG. My biggest problem is lack of familiarity with the fish. I've never seen a live one, but I hope to change that.

At this point, there seems to be a greater difference between northern BG's and coppers than what I initially thought. At least where gender definition is concerned.

My lack of experience with these southern fish is really showing through.

"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.
