Tips for Keeping Pond Fish in Southern Ontario

Depth and Size: Ensure your pond is deep enough to prevent freezing completely in winter. A depth of at least 2 feet is recommended for koi and goldfish.

Filtration and Aeration: A good filtration and aeration system is essential to maintain water quality and provide enough oxygen for your fish.

Feeding: Feed your fish a balanced diet appropriate for their species. During colder months, switch to a food formulated for lower temperatures.

Winter Care: In Southern Ontario, ponds can freeze in winter. Ensure there is a hole in the ice to allow for gas exchange. We would suggest using a de-icer and aerator if necessary.

Predator Protection: Protect your fish from predators like raccoons and herons by providing hiding places and using pond netting if needed.

Choosing the right fish for your backyard pond can create a vibrant and thriving aquatic environment. By considering the specific needs and characteristics of these fish, you can enjoy a beautiful and balanced pond year-round.
