First time I ever saw anything like it too. It's still hard to believe. I was thinking the peacock bass moved off the nest after spawning and are guarding the hatchlings just a little deeper than where the nest was. That brush hog was the perfect bait, in the right place, at the right time. It was really working. I still can't believe it.
(of course, confidence and skill of the angler had nothing to do with it... right?)
