Who knows about fish feeds? I normally feed Silver Cup fish food but I can only buy it from my supplier 85 miles away. I stopped in a local Tractor Supply and they had Nutri Source catfish food (13.00 bucks 50 lbs) and my bass hate it. I watched them take it in then spit it out. The feed was about 1/8 to 1/4 in diameter. Purina fish food is something I can get close by also. Does anyone feed this? Hey Greg did you get my e-mail sent to your company about my feeder?
