No. Stop feeding koi, goldfish, and other cold-water pond fish when water temperatures drop below 50°F (10°C).
As water temperatures decrease, fish become less active and their metabolism slows. They cannot properly digest food in very cold water. Feeding them during this time can cause health and water quality problems.
Koi and goldfish can typically go several weeks to a few months without eating during winter.
When should I start feeding again?
When pond water temperatures are consistently above 50°F (10°C) in the spring, gradually resume feeding with an easily digestible food such as Aquascape Premium Cold Water Fish Food Pellets.
Always use the pond water temperature, not the outside air temperature, to determine when to stop or resume feeding.
