Sera Goldy is flake food for the daily feeding of all goldfish in the aquarium and the garden pond. Goldfish need less protein and more easy-to-digest carbohydrates than tropical fish. Sera Goldy contains spirulina and wheat germ meal and is thus an ideal food for coldwater fish in the aquarium or in the pond. Feeding Sera Goldy in autumn and early spring strengthens the fish before and after hibernation.
