What good are catfish in a pond? Aside from table fare or as a target species, all they are is competition for your predator species. They really offer no benefit (other than bluegill control) if you happen to have that problem. They are not a desired species to me so I have zero reason to stock them.
As far as taking pellets I would bet once the weather warms it won't take long at all till they'll start taking pellets if you're consistent with time and location of feeding.
