I don't know if I would do that. Red spots have been known to hybridize with BG. If such occurrences are rare, then perhaps no detrimental effects would be realized. On the other hand, what if it happens regularly in your pond, which becomes more likely when sourcing fish from the wild where you're not sure if you're collecting breeding pairs, or just the more colorful males during spawning.

Red spots don't normally grow too large, and there is also the potential for unwanted hitchhikers when collecting wild fish. If it were me, I wouldn't do it, better to take the kids somewhere different for a day of catching pretty fish. But it's your pond, and I understand the attraction.

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.
