Awesome fish George! Even though those CNBG foil my efforts to sex them everytime, I'm going to put it out there again...

First BG photo....female.

Second BG photo....this one is confusing to me... chest coloration, round body dynamic, and I THINK I see scale tipping? That small opercular throws me though.... immature male?

Third BG photo....male.

Fourth BG photo....male.

How did I do?

"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.
