Tetra Color Crisps first three ingredients: fish meal (probably by-products=heads, bones, scales, etc.), dried yeast, corn starch, not a good start to any fish food, definitely not high quality. Next ingredients are shrimp meal (again, may be by-products), wheat gluten (boosts lab protein tests, even if it isn't available to the fish), brown rice (again, protein boost), and potato protein (again, increases lab protein tests). This food also includes artificial colors.
There are MUCH better foods out there, feed as good as you can.
Their veggie flakes are about the same except algae meal is the fourth ingredients (my be very little compared to the first three ingredients). I guess that is where the spirulina is since it isn't listed elsewhere in the ingredients.
Both formulas contain ethoxyquin.
