This flake is a blend of our four specially formulated flake diets: * Brine Shrimp Flake * Spirulina & Kelp Flake * Mysis and Garlic Flake * Plankton Gold Ideal for marine and freshwater community tanks. The Deli Flake is one package with each one of the four flakes. (Like a tossed salad with four different types of salad leaves) We use all natural ingredients - no artificial colors or preservatives! And you will feel comfortable knowing that all of our flakes are made in small batches to ensure freshness.
