What makes Dupla Gel-O-Drops Krill so healthy and nutritious for your fish? Krill are tiny, shrimp-like crustaceans found in the world's oceans, and are a natural food source for many sea creatures, including fish. Krill is packed with high quality proteins that are essential for animal growth. In addition, krill is an excellent source of omega-3 fatty acids, especially EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These fatty acids promote health, strengthen the immune system and improve the basic functions of your fish. The naturally occurring carotenoids in Dupla Gel-o-Drops Krill, especially astaxanthin, enhance the colours of your fish. In addition, krill contains a wealth of antioxidants that help protect your animals' cells from harmful free radicals. This supports the longevity and vitality of your aquarium creatures.
