I typically gut load my crickets with potatoes and carrots. I alternate the days I feed carrots and the days I feed potatoes. I have looked at several different brands/formulas for gut loading crickets. My co-worker makes his own by putting cherrios, fish flakes, and a few other ingredients in a blender and gut loading his crickets in powder form. What is the best mix/brand to use specifically for crickets being fed to a Pacman? Is powder or cube form the best?
