sera Goldy Color Spirulina Nature is the color food consisting of gently manufactured granules without dyes and preservatives for bigger goldfish, fastidious fancy variants and other finicky coldwater fish. The balanced and easily digestible composition with valuable ingredients such as spirulina (10%) supports the natural color formation of the splendid animals in a directed way. The colors become more intense and pure, and are clearly separated against each other. Healthy development and disease resistance of the fish are being supported. The floating granules keep their shape and do not pollute the water.
