There's a YouTube channel that I follow, Carrasco Ranch. He has a Catfish pond (Blues and Channels), and whenever he posts a feeding video, hundreds of FHM always come up to the feed. Anecdotal of course, but that stuck out in my mind when I mentioned a Catfish pond. I just don't see Catfish coming up to the shoreline in less than a foot of water to chase around minnows like BG/LMB do. Of course they'll eat them, but Catfish aren't great predators. Not like other species anyway.
