the makers of spectrum have basically formulated a specific diet with the right amount of nutrients.
they fed their fish certain nutrients, all measured out.
x amount of carbohydrates
x amount of protien.
etc etc
then they tested the fish poo, to see what nutrients were used and what was left over in their poo
by doing so they worked out exactly what nutrients a fish needs, and at what levels each nutrient should be supplied
what they found is carnivores and herbivores need the same amount of nutrients, the only difference is the way they get it (one eats fish, the other plants)
they then come up with a nutrient rich pellet which is the perfect balanced diet for nearly all fish.
thats why spectrum gives good natural colouring, it doesnt foul your water like other foods, and you dont need to supplement your fish's diet with other foods to try get the right nutritiion to your fish.
in a nutshell its a scientifically balanced and complete nutrition formula
