Reptile POTZ (Temperature Zone) Guidereptile

Determine the Preferred Optimum Temperature Zone (POTZ) for common reptile species and assess whether current enclosure conditions are appropriate. Covers basking temperature, cool side temperature, nighttime temperature, and humidity range for: Bearded Dragon, Ball Python, Leopard Gecko, Corn Snake, Red-eared Slider, Green Iguana, Veiled Chameleon, Box Turtle, Blue-tongued Skink, and Boa Constrictor. Reptiles are ectotherms that require a thermal gradient to thermoregulate; incorrect temperatures lead to immunosuppression, poor digestion, respiratory infections, and failure to thrive. Used for husbandry assessment, new enclosure setup, sick reptile workup (check husbandry first), and client education. Common queries: what temperature for my bearded dragon, ball python heat requirements, reptile tank temperature, is my reptile too cold, POTZ for reptiles.
