Sorry Scott. GFC is Game Fish Chow by Purina. It is 32% protein and has multi sized pellets to cover all sizes of fish.

"What is the difference between carnivorous and omnivorous fish foods? "

Usually the % protein and its source. Omnivorous don't need as high a % protein and their food has plant material as a higher protein source as opposed to fish meal. Fish meal costs more than plant material (usually soy products).

CC will do fine with AM 500 as a supplemental food source.
