Guppies have specific requirements for water temperature, and the suitable temperatures for different growth stages and scenarios are as follows:
1. Daily Rearing Temperature
Fry
The optimal water temperature is 24-27°C. Higher temperatures help accelerate metabolism and growth.
Adult Fish
Suitable at 22-28°C, with 24-26°C being the range where their body color is most vibrant and vitality is best.
General Range
22-28°C is the safe interval, with 26°C as the ideal temperature.
2. Temperatures for Special Scenarios
Breeding Period
Adjust to 26-28°C to promote estrus and increase egg hatching rates.
Winter Maintenance
Use a heater to maintain ≥20°C. Temperatures below 15°C may be fatal.
Summer High Temperatures
Exceeding 30°C can cause oxygen deprivation; use cooling equipment for control.
3. Precautions
The temperature difference between old and new water during water changes should be <2°C to avoid stress.
Sudden temperature changes easily trigger white spot disease or fin clamping.
Prolonged low temperatures (<20°C) lead to reduced appetite and decreased immunity.
