The optimal water temperature range for Siamese fighting fish and relevant suggestions are as follows:
1. Core Temperature Zones
Ideal range: 24–28°C (Similar to the prime years of humans, when the fish's bodily functions are most active)
Special need during breeding period: Raise the temperature to 26–28°C to promote reproduction
Juvenile fish care: It is recommended to strictly control the temperature at 24–26°C (juvenile fish are more sensitive to temperature)
2. Dangerous Thresholds
Risks of low temperature:
Below 15°C may trigger hibernation or death
Prolonged exposure below 22°C easily leads to enteritis and growth stagnation
Risks of high temperature:
Exceeding 32°C will cause oxygen deficiency and organ failure
Short-term exposure above 30°C may cause "tail burning disease"
3. Seasonal Management Tips
Summer:
Use a fan to blow the water surface to cool down by 2–3°C (avoid direct sunlight)
Winter:
Use a heater to maintain the temperature above 22°C
Notes on water change: The temperature difference should be controlled within 1°C to avoid stress
4. Equipment Recommendations
Select a heater at 1 watt per liter of water (for example, a 50W heater is suitable for a 50-liter fish tank)
Match with a precise thermometer with an error of ±0.5°C
Key reminder: The stability of water temperature is more important than the absolute value, and a sudden change exceeding 3°C may be fatal. Observing the appetite and swimming state of Siamese fighting fish can help judge whether the water temperature is appropriate.
