When goldfish are suffering from oxygen deficiency, the following methods can be adopted to address the issue:
Increase Oxygen Supply: You can use an oxygen pump or air pump to increase the oxygen content in the water. These devices produce bubbles, which help dissolve more oxygen in the water, thus meeting the breathing needs of goldfish.
Replace Water Quality: Regularly change the water in the fish tank to ensure the water is clean and contains sufficient dissolved oxygen. You can treat the new water with a de - chlorinator to avoid the harm of chlorine to goldfish.
Control Stocking Density: Reduce the number of goldfish in the fish tank to avoid over - stocking. This can decrease the oxygen consumption in the water and maintain the oxygen content in the water body.
Increase Water Flow: Install a filter or water pump to increase the water flow. This helps distribute oxygen evenly in the water and improves the breathing efficiency of goldfish.
Adjust Water Temperature: Use a thermometer to monitor the water temperature and ensure it is within the suitable range for goldfish (usually 18 - 24 degrees Celsius). If the water temperature is too high, you can lower it through a cooling device or adjusting the indoor temperature.
Isolate Individually: Isolate the oxygen - deficient goldfish in a separate basin to reduce its stress and make it easier to observe and handle its condition.
Add Appropriate Amount of Salt: Add an appropriate amount of salt to the water (a concentration of 3‰ - 5‰). This can help regulate the osmotic pressure of the water and reduce the burden on the goldfish's kidneys.
Blow with Cold Air: Gently blow the water surface with the cold air from a hair dryer to lower the water temperature, thereby increasing the oxygen content in the water.
Measures to Prevent Goldfish from Suffering Oxygen Deficiency Include:
Clean the Fish Tank Regularly: Keep the fish tank clean and avoid the accumulation of waste, which may affect water quality.
Control Stocking Density: Arrange the number of goldfish reasonably according to the size of the fish tank to avoid over - stocking.
Increase Water Mobility: Maintain good water flow through a filter or water pump.
Pay Attention to Temperature Changes: Avoid the water temperature being too high or too low and keep it within the appropriate range.
