Reptile Tank Temperature Chart
Reptiles need a temperature gradient to regulate their body heat. Typical basking, warm-side, cool-side and night temperatures for popular pet reptiles.
Reptile temperature guide
| Species | Basking / warm side | Cool side | Night |
|---|---|---|---|
| Bearded dragon | 95–110 °F (35–43 °C) | 75–85 °F (24–29 °C) | 65–75 °F (18–24 °C) |
| Leopard gecko | 88–92 °F (31–33 °C) | 70–77 °F (21–25 °C) | 65–70 °F (18–21 °C) |

| Crested gecko | 78–82 °F (26–28 °C) | 72–75 °F (22–24 °C) | 65–72 °F (18–22 °C) |
| Red-eared slider | Basking 85–95 °F (29–35 °C) | Water 75–80 °F (24–27 °C) | 70–75 °F (21–24 °C) |
Notes
Reptiles are ectotherms: they move between warm and cool areas to control their body temperature, which affects digestion and immunity. Measure with a digital probe or infrared thermometer at the basking spot and on the cool side, and run heaters on a thermostat. Crested geckos are stressed above about 82–85 °F. Care requirements vary by species and source — follow a reputable care sheet or a reptile veterinarian.
Frequently asked questions
What temperature should a bearded dragon tank be?
Basking spot 95–110 °F, cool side 75–85 °F, night 65–75 °F.
What temperature does a leopard gecko need?
Warm side surface 88–92 °F, cool side 70–77 °F.
Do reptiles need heat at night?
Many tolerate a drop to the mid-60s °F; add heat only if it falls lower.
Why does my reptile need a gradient?
So it can warm up or cool down as needed by moving around.
