The first picture is a little late. Some are already eating!
Fed last night and got a pretty good response and fed more than I normally feed till they almost quit. Fed the smaller pellets and they attacked it again which says to me that only a percentage are eating.
Now if Bob can just get Purina to make a large catfish pellet. My large catfish eat untill the feed gets scattered a little and then quit. Those tiny pellets just get pushed to the side to fast.
