Flakes and pellets will keep your fish alive, but that's about it. The frozen you feed is just so much better
I spend more each month on fish food than I do anything else (well, not counting electricity because that's a 'hidden' cost).
Can you tell us Paul, exactly what you feed your fish.
Today it is not only possible, but relatively easy, to maintain systems with acceptably low nutrient levels whilst also feeding your fish to healthy levels.
