I just posted about ducks in a stock tank too. But same tank as the other thread. We've been putting a bunch of 2 and 3 lbs and one or two four pounders in this tank. It's fun now to go out with a top water and consistently catch fish. We put 1000 jumbo minnows two years ago and have thrown perch in as well. No catfish. The tank has no real cover for the bait fish, which is good and bad. When you walk over to the shallower end you still see good amounts of minnows. My dad wants to start feeding the fish, but he's curious will it make the bass not bite or be as active when we fish? Is there a good brand to feed fish other catfish really?
