Choose a natural high-quality food for your ornamental pond fish with Tropical Koi Silkworm & Astaxanthin. Enhances natural colour. Contains 10% dried silkworm pupae. Diversify the diet of your fish in the warmer weather (15 degrees Celsius and 30 degrees Celsius), when the metabolism of your fish is at its highest. This pellet formula utilizes high-quality easy absorbing sources of protein to accelerate the growth of fish, body development and shape. Low carb diet promotes healthy muscle growth and decreases fat deposition for a fish that is ready for exhibition. Koi Silkworm & Astaxanthin also includes a high content of fatty acid that greatly improve the condition of the skin. Additionally, a high content of astaxanthin and carotenoids from sources such as marigold, peppers, and spirulina, dramatically intensifies colours, like red, yellow and orange in ornamental fish.
