Ouch!
Don't recall any serious disagreement with sellers.
I'd just dodge them if dissatisfied.
Too stingy to share a flathead with someone I didn't like!
Or channel cat. (No blues here).
A bullhead? Maybe. If I only had one and wasn't hungry.
A lake we used to fish trout in at night had some big yellow bullhead. Friend thought some master angler (a program the state runs with a minimum weight per specie for recognition. Length if released) size were in there.
I just filleted them and measured them with a hot oiled skillet!
Bullhead meant we were in too warm of water though so we'd move if catching them.
Buddy feeling the anchor to check how cold it was....About made work out of fishing sometimes. L.o.l..
