Guide to Water Temperature Management for Chinese Betta and Thai Betta
Key Points for Chinese Betta Water Temperature Control
Optimal Range: 24-28°C (25-26°C is the golden range)
Breeding Period: Need to raise the temperature to 26-28°C (nest-building success rate increases by 70%)
Juvenile Stage: Strictly maintain 26°C ±1°C (temperature difference >1°C is likely to cause spinal deformities)
Risk Warnings:
<20°C: Metabolic rate decreases by 15%, risk of enteritis increases
30°C: Dissolved oxygen drops sharply, tail burn disease is highly prevalent
Water Temperature Requirements for Thai Betta
Suitable Range: 22-24°C (minimum tolerance is 20°C)
Characteristic Differences: More sensitive to low temperatures compared to Chinese bettas
Breeding Assistance: It is recommended to maintain a constant temperature of 28°C
Seasonal Management Tips
Summer Cooling:
Use fans/ice packs to control temperature difference (single cooling ≤2°C)
Avoid direct sunlight (water temperature can rise by more than 5°C suddenly)
Winter Insulation:
50W heater to maintain above 22°C
Daily temperature rise ≤3°C (to prevent stress shock)
Equipment Recommendations
Basic Configuration: Digital display heater + independent thermometer
Advanced Plan: Temperature alarm + protein skimmer
Note: The temperature difference between old and new water should be <2°C when changing water for all bettas. Thai bettas are sensitive to PH value (6.5-7.2 is recommended).
