Protein requirements for goldfish and koi fish feeding is primarily determined by water temperature. In cool water, 42° to 70°F (6° to 21°C) fish will feed but do not require a high protein food. Feeding excess protein does not benefit the fish and will convert to poisonous ammonia. This is especially dangerous in cooler water because the bacteria that comprise the biological filter are inhibited by cooler temperatures.
