During cold weather, fish require food that is high in energy and carbohydrate and low in fat and protein.
A wheatgerm-based fish food is ideal. It can be fed to goldfish and koi in water as cold as 40°F (4.5°C).
Feed fish with a wheatgerm-based food for the months of April/May and October/November or when the water temperature is consistently BELOW 55°F (13°C).
