With superior color enhancing capacity, Hikari Bio-Pure Freeze-Dried Krill are an excellent treat for arowana, turtles, frogs, koi, and most larger freshwater and marine fishes. Made using pharmaceutical freeze-drying techniques, this product is as close to fresh as humanly possible and has a texture and taste not previously available in freeze-dried food. This krill is multi-vitamin rich to reduce stress and stress related diseases, and is nitrogen charged to reduce oxidation prior to opening. Once opened, oxygen absorbers reduce oxidation, which means less waste and lower cost per feeding. Freeze-Dried Krill are packed in whole pieces, which promotes feeding by hand and allows you to dispense the right amount of food, therefore eliminating over-feeding and water clouding. In addition, they are free of parasites and harmful bacteria, and are made with reduced salt content to reduce potential long term health problems.
