I use the Purina Fish Chow 32% protein mix. I like it predominantly because I think the variety of pellet sizes allow the bait to drop to different levels. I like it because it floats and I get to see the fish strike on top of the water. Dog food has alot of corn products in it that are not easily absorbed by fish and the protein is substantially low to really bulk the fish up. If you want to grow big fish quickly I would spend a little extra on the purina fish chow
50# cost $15.25 at a local feed mill.
