GOLDFISH COLOUR PELLET colour-enhancing granules for goldfish. GOLDFISH COLOUR PELLET is a colour-enhancing food in the form of tiny, floating granules, intended for everyday feeding of all species of goldfish and young koi, kept both in tanks and ponds. An exceptionally rich formula of GOLDFISH COLOUR PELLET has been developed to match sophisticated dietary needs of cyprinids, ensuring their proper growth, development and excellent condition. Natural carotenoids, including easily assimilable astaxanthin, intensify coloration, especially red, orange and yellow colours. The immune system is enhanced by stabilised vitamin C and beta-glucan – a natural immune stimulator derived from yeasts.
