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