Maybe the guy ordered some 'shiners' for forage fishfor his pond and that's where the buffs and quillies came from.
Deb has pictures in her archery shop of some guys holding some really good sized bigheads. I asked her where they shot them and she said "farm pond". Farm pond??
The guy who owned the farm pond ordered some sterile grass carp. Fish were delivered and stocked. Turns out they were bigheads not grassies.
