Foods arnt made equal by any means and ingredients are everything.
Just look at the ingredients for new life spectrums BETTA formula:
Whole Antarctic krill meal, whole herring meal, whole wheat flour, algae meal, garlic, soybean isolate, beta carotene,*spirulina, vegetable and fruit extract (spinach, red and green cabbage, pea, broccoli, zucchini, tomato, red bell pepper, kiwi, apricot, pear, mango, apple, papaya, peach), vitamin a acetate, DL alphatocophero (E), d-activated animal sterol (D3), vitamin B12 supplement, thiamine, riboflavin supplement, pyridoxine hydro-chloride, calcium pantothenate, L-ascorby-2-polyphosphate (stable C), choline chloride, copper proteinate, ethylenediamine dihydroiodide, cobalt sulfate, ferrous sulfate, manganese sulfate.
