Husbandry requirements

Veiled chameleon — origin: Yemen and Saudi Arabia — high plateaus.

Terrarium temperature gradient

Night min18 °C
Cool side22–24 °C
Warm side24–28 °C
Basking spot30–35 °C

Hot spot with no direct contact (risk of burns)

Enclosure (adult)
60 × 60 × 120 cm

Mesh (screen) terrarium, densely planted

Ventilation critical; strictly individual housing

Humidity
50–70 %

Misting 2×/day + a dripper; let it dry out between the two

Substrate
Bare floor or a draining bioactive substrateAvoid loose substrate (impaction)
UVB
Recommended

ESSENTIAL — UVB (Ferguson zone 3) + a hot spot

Water source
Always available

NO water bowl — drinks droplets; a dripper/misting are mandatory

Origin
Chamaeleonidae

Yemen and Saudi Arabia — high plateaus

Feeding & health

Diet

Insectivore (also nibbles plants) — Crickets, dubia, hornworms, silkworms — gutload + calcium; non-toxic plants

Calcium without D3 frequently + occasional D3/multivitamins if UVB is present

Breeding
Oviparous

Clutch 20–80 eggs/young. Females lay even without a male → a laying bin is essential; risk of egg retention

Health watch points
  • MBD (lack of UVB/calcium)
  • Egg retention / follicular stasis (females)
  • Dehydration
  • Stress
  • Thermal burns
  • Respiratory infections (too humid/poorly ventilated)

Frequently asked questions

Answers to the most common questions about keeping the veiled chameleon.

Where does the veiled chameleon come from, and is it suitable for beginners?▾
It hails from the high plateaus of Yemen and Saudi Arabia. It is of intermediate difficulty and not ideal as a very first reptile: its ventilation, hydration and UVB requirements, along with the fragility of females, already call for a certain level of rigor.
How big does it get, and do males differ from females?▾
Sexual dimorphism is pronounced: males reach 35-60 cm and sport a large casque, while females stay smaller, between 25 and 35 cm, with a much smaller casque.
What kind of terrarium is needed?▾
Plan for a densely planted mesh (screen) terrarium of at least 60 x 60 x 120 cm, with height taking priority since the animal is arboreal. Ventilation is critical, and each individual must be housed strictly alone.
Can it be handled or kept with others?▾
No: it is a solitary, territorial animal, best regarded as one to observe rather than handle. Handling stresses it, and two individuals will not tolerate each other, which requires individual housing.
What does the veiled chameleon eat?▾
Mainly insectivorous, it eats crickets, dubia roaches, hornworms and silkworms, all pre-fed (gutloaded) and dusted with calcium. It also nibbles non-toxic plants, which helps with its hydration.
How do you get it to drink?▾
It does not drink from a bowl but licks droplets off the foliage. A drip system and misting are therefore mandatory; without them, dehydration sets in quickly.
What temperatures and humidity should be maintained?▾
Provide a basking spot of 30-35 °C, a warm zone of 24-28 °C and a cool side of 22-24 °C, never dropping below 18 °C at night; the lamp must stay out of direct reach to avoid burns. For humidity, aim for 50-70% with two mistings a day plus a dripper, letting things dry out in between.
Is UVB essential?▾
Yes, UVB lighting (Ferguson zone 3) combined with a basking spot is essential. It enables vitamin D3 synthesis; you then supplement regularly with calcium without D3, adding D3 and multivitamins occasionally.
Is a laying bin needed even without a male?▾
Yes, absolutely: females lay eggs even without a male present, with very large clutches of 20 to 80 eggs. A laying bin is essential, and controlled feeding helps limit both egg overproduction and the risk of retention.
What substrate should be used?▾
Favor a bare floor or a well-draining bioactive setup. Loose substrates should be avoided, as they carry a risk of impaction if swallowed while catching prey.
What is its life expectancy?▾
Males live 5 to 8 years, while females tend to live 4 to 6 years, with the wear from repeated egg-laying explaining this difference.
What health problems should be anticipated?▾
The most common are metabolic bone disease (lack of UVB or calcium), egg retention and follicular stasis in females, dehydration, stress, thermal burns, and respiratory infections encouraged by excess humidity or poor ventilation.
