What makes our Krill Flake the best flake on the market - ingredients and production. We start with the best marine proteins, add farm-raised spriulina algae and all the required vitamins and minerals as well as some extra natural ingredients to promote health and encourage breeding. Then we flake it so it crisp and thin and you get our Krill flakes. We've had it for many many years as Marine Crave Flakes, now after lots of input from our customers we are promoting it for freshwater aquariums as well. So far, we have found no other flake like it on the market. When you combine forty-five years of hands-on-fish-keeping-experience, terrific ingredients and quality manufacturing right here in the USA, you come up with Xtreme Aquatic Foods. Xtreme Krill Flakes is made with the finest quality ingredients, with Krill being the first main ingredient. The flakes can be easily crumbled in your fingers to suit any size fish which you might be feeding. These flakes are a great source of protein, and this krill based food will help your fish's natural colours really pop. Eagerly accepted by both freshwater and marine fish. The wild caught krill used in Xtreme foods is sourced from either the waters off Alaska or South Africa, depending on time of year. The pink hue of the flakes may vary depending on time of year and krill source area used.
