Veiled chameleon care guide
Chamaeleo calyptratus
Needs airflow above all — screen or hybrid enclosures only, densely planted, with a strong vertical thermal gradient.
Arboreal — vertical height first
Veiled chameleon enclosure size
Arboreal — vertical height first. An adult veiled chameleon should live in at least 24" L × 24" W × 48" H; we build toward 36" L × 24" W × 48" H (3 × 2 × 4 ft, roughly 6 sq ft of floor and about a 180-gallon glass equivalent).
Always housed alone — chameleons are solitary and stressed by sight of others.
- Hatchling / baby
- 18" L × 18" W × 24" H recommended · min 16" L × 16" W × 20" H
- Juvenile
- 24" L × 24" W × 36" H recommended · min 18" L × 18" W × 36" H
- Adult
- 36" L × 24" W × 48" H recommended · min 24" L × 24" W × 48" H
Temperature and heating
Single halogen above the screen top with a basking branch beneath it.
- Basking / warm surface
- 85–95°F at the top perch (adults toward the higher end)
- Warm side (ambient)
- 75–85°F mid-level
- Cool side (ambient)
- 70–75°F at the bottom
- Night
- 60–70°F night drop is important
Lighting and UVB
UVB: Linear T5 UVB 6% over the screen (UVI 3 at top perch). Run lights on a 12 hours photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.
Humidity
Target Spikes to 100% at night, drying to 30–50% by day. Dripper plus heavy morning/evening misting; must dry fully between cycles.
Substrate and depth
Bare bottom or bioactive soil with drainage. Depth: 0–3 in.
Enclosure tips and furnishing
- Dense network of thin branches and vines
- Live plants (pothos, ficus)
- Dripper for drinking
- Laying bin for females
Build list
- 2x2x4 screen or hybrid enclosure — Chameleons need constant airflow; glass boxes cause respiratory infection.
- T5 UVB 6% + halogen above the mesh — UV through screen loses strength — mount correctly.
- Digital thermostat — Every heat source must run through a thermostat — unregulated heat burns animals.
- Two digital probe thermometers + hygrometer — Read the warm side, cool side and humidity directly — stick-on dials are inaccurate.
- Misting system / dripper — They only drink moving water.
- Live plants and vines — Cover is the difference between a calm and a stressed chameleon.
Veiled chameleon FAQ
How big should an adult Veiled chameleon enclosure be?
At least 24" L × 24" W × 48" H, and we recommend building to 36" L × 24" W × 48" H — about 3 × 2 × 4 ft, or a 180-gallon glass equivalent. Arboreal — vertical height first.
What temperatures does a Veiled chameleon need?
Basking or warm surface 85–95°F at the top perch (adults toward the higher end), warm side 75–85°F mid-level, cool side 70–75°F at the bottom, night 60–70°F night drop is important. Single halogen above the screen top with a basking branch beneath it.
