New Life Spectrum Optimum Flake food is for smaller community fish and surface feeders. This easily digestible food contains whole antarctic krill, spirulina, garlic, whole fish and more. Optimum is the most nutrient-rich flake available.
Rivers to Reef says: This is probably the best flake food on the market. Because they use whole krill this food is more easily digestible for herbivores, omnivores, and carnivores. We usually recommend trying to get your fish (especially larger fish) to eat pellets as they are more nutrient packed, but if you wanted to feed a great flake food, these are the flakes for you.
