sera Goldy Gran is the staple food consisting of carefully manufactured granules for bigger goldfish and other fastidious coldwater fish. Due to its high quality ingredients such as wheat germ (4%), omega fatty acids and mannan oligosaccharides the food is excellently digestible and provides even very fastidious fancy variants with all required nutrients. The fish thus grow strongly without fattening, and disease resistance is enhanced. The floating granules keep their shape for a long time and do not pollute the water.
