Recommended Tank Sizes
Enclosure size guidance by life stage for Desert Iguana. General guidelines — always research species-specific requirements and size up whenever possible.
10–20 gal (38–76 L), 20" × 10" (51 × 25 cm)
30–40 gal (114–151 L), 36" × 18" (91 × 46 cm)
50–60 gal (189–227 L), 48" × 18" (122 × 46 cm)
75+ gal (284+ L), 48" × 24" or larger (122 × 61 cm or larger)
Ferguson Zone & UVB
The Ferguson Zone system categorizes reptiles by their natural UVB exposure needs, guiding lighting choices.
These reptiles bask in direct sun for extended periods. Provide moderate-to-high UVB (10–14% T5 or Mercury Vapor bulb) covering 1/2 to 2/3 of the enclosure, with shaded retreats.
Zone 1
Crepuscular / Shade
Zone 2
Occasional Basker
Zone 3
Open Sun Basker
Zone 4
Full Sun Lover
Temperature Gradient
basking surface
100–110°F (38–43°C)
warm ambient
85–95°F (29–35°C)
cool side
75–80°F (24–27°C)
Humidity
20–40%
Lighting & Photoperiod
10–14% T5 HO UVB bulb spanning 1/2–2/3 of the enclosure. Basking bulb (halogen or incandescent) on the warm end. 12–14 hr photoperiod in summer, 10–12 hr in winter.
Heating
Overhead halogen basking bulb (preferred) or ceramic heat emitter for nighttime heat if needed. Under-tank heat mats are a secondary option for belly warmth.
Decor & Furnishings
- •Flat basking stones under the heat lamp
- •Cork bark or rock caves for hides (one on each end)
- •Excavator clay burrowing mound
- •Dry branches for climbing opportunities
- •Shallow water dish on the cool side
Setup Notes
Provide a deep substrate layer (4–6 in / 10–15 cm) for burrowing. Use a temperature gradient from basking zone to cool side. Offer a humid hide (damp sphagnum moss) to aid shedding, even in arid setups.
