Speaking of bullhead predators (me, in this case). I'll never forget the day when I was sixteen years old. I was fishing a weedline at Hedgefield Lake and I saw my first "bullie ball" swimming nearby. I was fascinated by the seemingly thousands of black whiskered fish swimming in this tight formation. Since I was wading inside of a band of american pondweed the bullheads were oblivious to me as they swam within a foot of me. Like a big stupid heron I crouched and at the right instant I lunged my hand out to grab them, unaware of the spines that awaited me! Not one to generally use profanity I screamed every possible bad word in the book as I looked at the twenty or so bullies that were dangling off of the palm of my hand.
Lesson learned, I guess. Never did that again.
