Cobalt Aquatics has worked hard to bring you the ultimate solution to daily feeding of your herbivorous tropical and marine fish with Ultra Spirulina Flakes. This algae-rich flake food has been augmented with 20% spirulina content, a superbly nutritious food especially great for fish with more delicate digestive tracts. Also included in the formula are astaxanthin, paprika and garlic, all of which intensify coloration, boost immune system functionality and improve palatability. Ultra Spirulina Flakes also include Cobalt's base formula, featuring Cobalt's special BLUE flake, which is packed with a tripled concentration of vitamins designed to promote overall long term health and resilience. Healthy probiotic bacteria is another key ingredient in this formula, with Bascillus sp. bacteria helping to form the foundation of a healthy digestive system in fish. This is one of the best balanced, most advanced nutritional formulas on the market for daily herbivorous fish feeding, and Cobalt has made sure it does not cloud your water or add needless waste to your ecosystem!
