Water Temperature Guide
70 degrees (21°C) and above: Business as usual
This is your “normal” fish feeding routine for warmer weather. Feed your fish up to four times a day, with their regular high protein food.
60-70 degrees (15.5°C-21°C): Slowing down
It’s time to start feeding a little less as fish metabolisms begin to slow down. Feed only one to two times a day, making sure there is no leftover food. Trim any brown leaves on plants.
50 to 60 degrees (10°C - 15.5°C): Get ready for cold water
Start to incorporate cold water fish food, or add in wheat germ. Wheat germ is easily digestible and full of nutrients and will help with the transition. It might be time to cut back your plants for overwintering.
Under 50 degrees (10°C): Getting ready
Fish do not require food when the water temperatures go below 50 degrees, as their bodies will no longer metabolize it. It's time to remove cold-sensitive plants and move them indoors, or dispose of them properly.
Under 40 degrees (10°C): Winter time!
Any water features that circulate the water should be removed before the pond's water temperature drops to 40°F. If your system freezes with water inside, your pump can be damaged and tubing can crack. You can choose to overwinter fish in the pond as long as there is a hole for air and your pond isn't at risk of freezing solid. All plants should be stored underwater, indoors, or disposed of.
