I had one place deliver Gambusia mixed in with FHM, and were 500 short on the count. Needless to say I scratched them off of my supplier list.
I pretty much inspect and count from new places I do business with. I inspect all fish I put in customers ponds, while tempering.
None of my places have bullheads to mix in. I once got an lmb in a bg load. And sometimes res and bg intermixed. Even when I get junk harvests, I'll get bullfrog polliwogs, crawdads, gsf, res and bg. Normally I'll get those for free. A known reputable hatchery or farm should not have bullheads to begin with. That is the first time I ever even heard that.
