Feeding time tonight, warmer water, hungry fish streaming towards me as I walked up, empty handed.

Then, when no feed came, began the accusatory stares....silent mouthing of threats...vulgar name-calling....obscene fin gesturing.

This is going to get ugly.

"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.
