Caring for Your Fish in Winter and Spring: Tips for a Healthy Pond

Keep your fish happy year-round

Pond fish, like koi and goldfish, need special care during the colder months to stay healthy. As winter continues, your fish enter a state of dormancy, and it’s the perfect time to focus on creating a safe, balanced environment for them. With proper care now, you’ll ensure they thrive when spring arrives.

Winter care for your pond fish

In winter, maintaining your pond’s health is essential, especially as ice starts to form. Here are a few key tips to keep your fish safe and happy:

1. Keep a hole in the ice:
   Use a de-icer or aerator to maintain an open hole in the ice. This allows harmful gases to escape and ensures oxygen can enter the water.

2. Ensure proper oxygenation:
   Position an aerator near the water's surface to circulate air and improve oxygen levels.

3. Monitor water quality:
   Check your pond’s water quality periodically, especially after heavy snowfall. If you need to add water, ensure it’s dechlorinated if pulling from city water.

Preparing your fish for spring

As temperatures start to rise and your pond wakes up from winter, it’s time to transition your fish back to an active season:

1. Schedule a professional pond cleanout:
   A thorough cleanout removes winter debris, refreshes the water, and creates a healthy environment for your fish.

2. Wait to feed your fish:
   Hold off on feeding until the water temperature reaches 10°C. Start with an easily digestible cold-water fish food to accommodate their slower metabolism.

3. Watch for signs of stress or illness:
   Monitor your fish closely for any signs of sluggish behavior, sores, or other health concerns. Addressing issues early ensures a healthy transition into the warmer months.
