Moroccan Uromastyx ("niger")

Quick sourced reference values. LOCUS Scales' full breeding/genetics toolset is built specifically for ball pythons — this page is a courtesy reference for other species.

Scientific name
Uromastyx nigriventris
Native range
Morocco
Lifespan
15-20 years (sometimes 25+)
Lifestyle
🌍 Terrestrial, burrowing — deep burrows in desert habitat

Diet: Strictly herbivorous — dark leafy greens (kale, turnip/mustard greens, dandelion), rotating legumes/seeds. Minimal insects for juveniles only, never a diet staple — several recent sources advise against insects entirely.

Feeding frequency: Juvenile: greens daily. Adult: greens every 2 days, legumes/seeds always available.

Substrate: Sand or sand/soil mix, deep (6-8in) to allow real burrows — a very burrowing species.

UVB: Essential, strong desert-type UVB (10.0/12%) — a species that literally basks in direct sun in the wild.

Incubation: Oviparous species. ~58-92 days depending on incubation temperature (84-92°F) — warmer incubates faster.

Clutches per mating: Generally 1 clutch per successful mating per season.
Average egg count: Up to ~20 eggs from a well-established female.

Warm side
52°C
Cool side
29°C
Humidity
25%

The most commonly kept uromastyx species — vivid orange/yellow coloring. Needs one of the largest enclosures in the genus (see adult size), easy to underestimate when buying a cheap small juvenile.

🏠 Enclosure size — Baby/juvenile: 36×18×18in · Sub-adult: 60×24×24in · Adult: 72×24×24in minimum

Common questions

Why does it need such an extreme basking temperature?
Unlike most pet reptiles, this species genuinely needs a 120-130°F hot spot — without that heat, digesting its fibrous plant diet doesn't work well, regardless of its size. Don't under-heat it thinking you're being gentle.
Why does its enclosure need to be so big?
It's one of the larger commonly kept uromastyx species (14-18in) — an undersized enclosure, often sold alongside the animal at pet stores, causes real chronic stress long-term.
Do I really need to feed it insects?
No — it's an almost strict herbivore. A small amount of insects for juveniles is tolerated by some sources, but never a diet staple like with a bearded dragon.
