Adult size: 10-18 inches (25-46 cm) depending on speciesLifespan: 15-25 years

Overview

Uromastyx are herbivorous lizards from North Africa and the Middle East, known for their spiny tails, colorful patterns, and basking behavior. They are diurnal, heat-loving lizards that thrive in hot, arid environments and make fascinating pets for keepers who can provide very high temperatures.

Ambient Temp

80-90°F (27-32°C)

Basking Spot

110-130°F (43-54°C)

Night Temp

70-80°F (21-27°C)

Humidity

20-35%

UVB

Required: strong 10.0-12.0 UVB covering most of enclosure; may need two bulbs

Lifespan

15-25 years

Enclosure Sizes by Life Stage

Life StageMinimum Enclosure Size
Hatchling0–3 months20-gallon long (30x12x12")
Juvenile3–12 months40-gallon breeder (48x18x18")
Adult12+ months4x2x2 ft or larger

Housing

Enclosure type
Terrestrial PVC or wood enclosure; retains heat better than glass; large footprint required
Substrate
Sand, sand/soil mix, or excavator clay (4-6 inches deep). They burrow extensively. Tile at basking area helps maintain heat.
Hides
Multiple hides; snug burrow-style hides preferred; dig boxes appreciated
Notes
Minimum 4x2x2 feet for adults. Provide large basking area, multiple hides, and open space. They need more length than height. Use PVC or wood enclosure to retain heat better than glass.

Temperature

Ambient / cool side
80-90°F (27-32°C)
Basking spot
110-130°F (43-54°C)
Nighttime
70-80°F (21-27°C)
Heating method
Basking bulb, deep heat projector, or halogen bulb; multiple heat sources may be needed

Humidity & Lighting

Humidity range
20-35%
Maintenance
Desert species requiring LOW humidity. Ensure good ventilation and avoid misting.
UVB
Required: strong 10.0-12.0 UVB covering most of enclosure; may need two bulbs
Photoperiod
14 hours on / 10 hours off; longer photoperiod supports healthy basking behavior
Lighting notes
REQUIRES strong UVB 10.0-12.0 covering most of enclosure. May need two bulbs. Also needs bright white basking bulb. UV output is critical for these desert species.

Feeding

Staple food
Dark leafy greens (collard, turnip, mustard greens), seeds, lentils
Variety
Dried flowers, commercial Uromastyx mixes; NO insects, fruit, or spinach
Frequency
Feed fresh salad daily or every other day for adults. Juveniles need daily feeding. Remove uneaten food.
Supplements
Dust vegetables with calcium (without D3) 2-3x per week. They can synthesize D3 from UVB. Multivitamin 1x per week.
Notes
STRICT HERBIVORE: Feed dark leafy greens (collard, turnip, mustard greens), seeds, lentils, dried flowers. NO insects, fruit, or spinach. Many commercial mixes available.

Water & Hydration

Water bowl
Provide water dish but they rarely drink; most hydration from vegetation
Notes
Provide water dish but they rarely drink. Most hydration comes from vegetation. Mist vegetables before feeding.

Handling

Disposition
Generally docile once settled; spiny tail used for defense; warm up before handling
Recommendations
Generally docile once settled but can be skittish. Handle 1-2 times per week. Their tail is spiny and used for defense. Move slowly and let them warm up under basking light before handling.

Common Health Issues

Metabolic bone disease from insufficient heat/UVB, impaction, respiratory infections from low temps, and vitamin deficiencies from poor diet.

Special Notes

Uromastyx can live 15-25 years. Multiple species vary in size and color. They NEED very high temperatures - this is not negotiable. May brumate in winter. Extremely food-motivated. Males are territorial and more colorful. They defecate urates (white solid uric acid) instead of liquid urine to conserve water. One of the few reptiles that can thrive on a completely herbivorous diet. High heating costs should be considered.
