As an experienced pond owner and a specialist in garden ponds, one of the most common questions I get asked is whether to feed pond fish during rainfall. In this article, I will discuss the factors to consider when deciding whether to feed your pond fish when it's raining.

Rain and Water Quality

Rain can have a significant impact on your pond's water quality. It can potentially introduce pollutants, lower the water temperature, and cause pH fluctuations. Why is my pond water dirty? To maintain a healthy pond, it's essential to monitor water quality regularly, especially during rain. You can use a hose pipe to top up your pond, but using rainwater is a more eco-friendly option.

Fish Behavior

When it's raining, fish may become more active, especially if the rain cools the water temperature. Koi and other pond fish may swim closer to the surface, making it easier for you to observe their behavior. If your fish appear to be hungry and actively searching for food, it's a good indication that you should feed them.

Feeding Considerations

Before feeding your pond fish during rain, there are a few factors to consider. First, ensure that you're using the appropriate type of fish food for your pond's inhabitants. Be cautious not to overfeed your fish, as uneaten food can negatively affect water quality. If you missed feeding your fish one day, it's important not to overcompensate the next day.

In colder weather, fish have slower metabolisms and require less food. Therefore, it's crucial to adjust your feeding routine according to the season. During winter, you may need to stop feeding your pond fish altogether. If your fish seem uninterested in eating during rainfall, it may be a sign that they're not hungry.


In general, it's okay to feed your pond fish when it's raining, as long as you monitor water quality, observe fish behavior, and provide the appropriate type and amount of food. For more pond-related advice and tips, visit
