Why are my pond fish gasping at the surface?
The reason they are at the surface trying to breathe is due to a lack of dissolved oxygen in the water. The low levels of oxygen are mainly due to a lack of aeration or poor water quality, which can then cause the fish to stress. Fish need different amounts of oxygen depending on the season.
How do you increase oxygen in a fish pond?
A very simple way to add oxygen to the pond is to add an air pump. Sitting at the side of the pond, it will pump air through a small hose to an air stone and bubbles will enter the water. When the bubbles break the water’s surface oxygen will then be added.

- Your pond will give off a foul odor.
- You’ll observe a thick layer of algae growing on the surface of the pond.
How do you naturally oxygenate water?
Oxygen enters water through diffusion from air, wind and wave action and plant photosynthesis. Dissolved oxygen levels are increased by supplementing wind and wave action, adding plants to water and exposing water to purified oxygen.

How do you know if your fish is struggling to breathe?
Symptoms of Low Oxygen Aside from actually testing the water for dissolved oxygen, the only indication of trouble will be the behavior of your fish. Fish will initially react to lower oxygen levels by simply moving around less. They will swim less vigorously and even eat less often.
