Tonight's candidates: A male RES and a male BG x RES hybrid. Since this is PondBoss and details matter, the RES went 10.25" and 14.4 ozs, and the hybrid was 10" and an even 15 ozs.

Outermost gill rakers on BG x RES hybrid.

Outermost gill rakers on RES.

BG x RES rakers

RES rakers.

Both together....RES on top, BG x RES on bottom.



In all of the photos I was doing my best to show the maximum extension of the rakers, to display length. I can also provide photos of the second row of rakers, if it would help.

"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.
