Matt, after taking a look at the ingredients and analysis of the Tropheus Lovers Flake food, I'm curious as to what would lead you to believe that this formula is a "really high quality food"?
Ken's Premium Tropheus Lovers Flake
While I understand that flakes require a binding agent, IMO there is no need for the soy flour, oat flour, corn gluten meal, or a massive amount of dried brewers yeast (the second ingredient listed by weight) What you have is a food that appears to be very high in starch/carb content. Also, going off of that ingredient list the only reason that food is green, is due to artificial coloring. IMHO that formula is at best a middle of the road food.
Someone earlier on in this discussion mentioned the earthworm food, yet when you take a close look at the earthworm sticks the amount of actual earthworms is somewhat questionable.
Ken's Premium Earthworm Sticks
Ingredients: white fish meal, fish protein concentrate, wheat flour, soy flour, gluten, dried brewer's yeast, frozen baby brine shrimp, plankton, shrimp, krill powder mix, earthworms, kelp meal, dried spirulina, fish oil, lecithin. The following vitamins/mineral supplements a, d-3, b1, b12, choline hcl, & biotin methionine. Vegetable protein. Thiamine (source of vitamin b1). Asorbic acid (source of vitamin c). Guaranteed analysis: crude protein 45.0% min., crude fat 4.1% min., crude fiber 4.2% max., moisture 8.2% max. All natural ingredients, except for some artificial coloring. No preservatives.
This is not about one brand vs other brands, nor am I questioning the results anyone has experienced with any of these products. My comments are soley geared towards assisting hobbyists in making informed decisions when researching the topic of fish food/nutrition.
