The suitable water temperature range for goldfish in winter is above 10°C, and the optimal water temperature is between 18 22°C. Within this temperature range, the activity level and appetite of goldfish will remain in a relatively ideal state, which is beneficial to their health and growth.
The Impact of Temperature on Goldfish
Below 10°C: The activity level and food intake of goldfish will decline significantly, affecting their healthy growth.
Below 5°C: The vitality of goldfish will decrease, influencing their growth.
Below 0°C: Excessively low water temperature may cause goldfish to freeze to death.
Winter Care Tips
Insulation Measures: You can use straw curtains, cotton curtains, or heaters to insulate the fish pond or fish tank to avoid overly low water temperatures.
Feeding Management: Goldfish have a decreased appetite in winter. Feed them in small amounts but multiple times to avoid indigestion.
Water Change Management: The frequency of water changes can be reduced in winter. Generally, change the water once a month, and control the amount of water change each time to be between 1/4 and 1/3. Pay attention that the temperature difference should not exceed 2°C.
Water Quality Management: Keep the water quality clean. Regularly clean the dirt in the fish tank and use a filtration system to maintain stable water quality.
Disease Prevention: Pay attention to the stability of water temperature and water quality to prevent goldfish from getting sick.
Through proper temperature control and scientific care methods, goldfish can grow healthily in winter.
