I really haven’t settled on one type. I used to use Tetramen – I could get it in a really large size from Fosters. Fosters is gone now. My fish love Wardley’s shrimp pellets – they are cheep and probably not the best, but I have used it for years. Right now I’m feeding a mix of Omega One Flakes, New Life Spectrum (2 sizes) and Cobalt pellets. Also organic salt free French Style Green Beans. Occasionally frozen blood worms and brine shrimp. Mircoworms for fry. Any recommendations for better food in larger quantities would be appreciated.
