My aquarium includes yellow lab, yellow peacock, aurora, kenyi, venustus and a couple of hybrid. A couple of them love the pellets while others spit them out. Flake food----well they barely look at that anymore. Blood worms they enjoy, but I quit as I read it bloats, and brine shrimp is ok. My question what is what is a good combination of food I can give them everyday to keep them happy and well fed? Also are blood worms ok for a treat?,,,,,say once or twice a week.
