Enclosure size guidance by life stage for Eastern Collared Lizard. General guidelines — always research species-specific requirements and size up whenever possible.
10–20 gal (38–76 L), 20"–30" long (51–76 cm)
30–40 gal (114–151 L), 36" × 18" (91 × 46 cm)

Ferguson Zone & UVB
The Ferguson Zone system categorizes reptiles by their natural UVB exposure needs, guiding lighting choices.
Rocky, semi-arid species are keen sun baskers. Provide moderate-to-high UVB (10% T5) over the basking zone, with rock crevices and caves for thermoregulation and security.
Zone 1
Crepuscular / Shade
Zone 2
Occasional Basker
Zone 3
Open Sun Basker
Zone 4
Full Sun Lover
Temperature Gradient
basking surface
95–110°F (35–43°C)
warm ambient
85–92°F (29–33°C)
cool side
75–80°F (24–27°C)
Humidity
30–50%
Lighting & Photoperiod
10% T5 HO UVB bulb over half the enclosure. Halogen basking bulb on deep heat pile rocks. 12–14 hr photoperiod in summer, 10–12 hr in winter.
Heating
Overhead halogen basking bulb aimed at a deep rock stack — rocks store and radiate heat. Ceramic heat emitter for nighttime if needed.
Decor & Furnishings
- •Deep rock stack under basking lamp (securely built)
- •Cork bark or stone caves
- •Excavator clay for burrowing structure
- •Slate or flagstone basking platforms
- •Shallow water dish on the cool side
Setup Notes
Stack rocks securely — avoid loose stones that could shift and trap or injure the animal. Rock stacks serve double duty as daytime heat reservoirs and nighttime retreats. Provide a humid hide for shedding support.
