The 3.5 ounce container of Hikari Bio-Pure Frozen Okanagan Lake Freshwater Mysis Shrimp is a high quality daily food for freshwater and marine fish species such as American cichlids, marine angels, grouper and stingray. The highly nutritious mysis relicta shrimp are harvested directly from the ancient glacier fed Okanagan Lake, and contains high levels of beneficial linolenic acid, omega-3 and omega-6 fatty acids, arachidonic acid, natural color enhancers, EPA and DHA as well. The outer shell of the all natural cubes provide natural chitosan, a sugar found in shellfish which is quite beneficial to a wide variety of fish. Additionally, the food contains high levels of planktonic algae with a flavour that drives fish wild and is sizable enough for large fish to rip and tear at the food as they would in their natural habitats. All cubes are gut loaded with bio-encapsulated multi vitamins for optimal nutrition and boast a three step sterilization process so aquarists can be confident knowing their aquatic creatures are receiving only the cleanest and healthiest food possible. Hikari Bio-Pure Frozen Okanagan Lake Freshwater Mysis Shrimp are prepared and packaged right on the shores of Okanagan Lake to eliminate the degradation of raw materials during transport as well as maintaining the nutritional content, natural color, taste and texture. The food has been verified by the UAZ Aquaculture Pathology Laboratory as being free of white spot syndrome, yellow head virus, myonecrosis virus and Penaeus vannamei nodavirus. Comes in convenient cubes for easily measured feedings.
