I don't think pellets larger than 1/4" are really beneficial for HSB until the fish get above 20"-22". At that size then I think the larger pellet becomes more efficient for the larger bodied fish.
Highest protein dog food that I think you will find is in the upper 20's (25%-30%). Compare the nutrient analysis item for item for dog food and high protein (40%-50%)fish food and I am pretty sure you will find more ingredients listed for the quality fish food. For sure, the best quaility fish foods contain different ratios of vitamins and amino acids that fish (cold blooded) need compared to dogs (warm blooded). A well versed nutritional scientist could explain the differences.

Who makes the 9.5mm pellet for the food you use?.
