I don't want to interrupt Bill, as he is far more knowledgeable than myself, but the orange tipped fins are usually indicative of a hybrid sunfish of some sort. Both males and females will display this coloration to some degree.

From your pics, I feel you definitely have Hybrids of some makeup in your pond. To be honest, I am not sure what to make of those last pics. HBG can show a lot of variation naturally, so they may be "standard" MBG x FGSF. I think you could be looking at a backcross of some sort, or a generation/s removed from the original F1's.

Again, trust what Bill says... I'm still trying to figure out all of this HBG stuff as I go....

"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.
