Average total length: 
Males 7.6in (20cm), Females up to 7.3in (19cm)
Longevity in captivity: 
Up to 9 years, Average 5-6 years
Longevity in the wild: 
2-3 years 
Temperature at daytime: 
Low 65-77s F (18-25°C)
Temperature basking spot: 
Low 82s F (28°C) 
Temperature at night: 
32-60s F (0-15°C depend from altitude) max; ideally udner 60s F (15°C)
Humidity at daytime: 
Below 50%

Special notes: Can die from basking too long (more than 30min) and at high temperatures.
Nighttime temperature deep drop and fogging inevitable.
Usually high altitude species, temporarily exposed to high UVI while basking.
Simulation of wind necessary.
Pollen builds a shield against bacterial infections.
Tiny flying feeders preferred.
