Well I have been in this hobby for 29 yrs now and by far the best food in my experience is Ken's fish food, I have witnessed excellent results with my Tanganyika's with this food, I feed high proteins so pay attention to what you are feeding whether they are Carnivore or Herbivore will depend on your foods.. Plus Ken's is reasonably priced, I use the 2mm pellet super grow which is a higher protein along with Earthworm Flake and Super brine shrimp flake also higher in proteins, I feed all of my Catfish species Ken's earthworm sticks and Grow sticks which is a really great bottom feeder food..
If I were to use another food it would be New Life Spectrum which is a great food as well and my third choice would be the Omega food brands.. Caution do not smell the Ken's earthworm pellets they are pretty smelly but my catfish love it and if it smells that bad than it has to be a good food..
But yeah the above information is right on with the foods that are low budgeted like aqueon, Top Fin, Wardley and a few others pretty much crappy and are full of fillers, Also watch the frozen foods they are mostly water for the price and is debatable if they retain much nutritional value you will get a better quality food as a pellet form than anything else..
Of course this is my opinion only.. And we know what opinions are..
