the quality does make a big difference, but lots of high quality =
lots of waste.
unfortunately, it is a myth that GF need veggies. Koi and GF cannot
digest
carbohydrates which is why peas give them diarrhea.
GF and Koi graze on the little high protein, high fat critters that
live on the green
stuff. They use fat for energy, protein for building muscles.
furthermore, they cannot digest all kinds of meat and fat, land based
animal protein
are too complex. stick to stuff lives in water as food. the best
foods are based on
krill. Ingrid

I could not agree more which is what I was trying to get across. Many
commercial foods are prepared with too much animal proteins. And yes
cereal in ALL fish is mostly roughage.
