Design Reptile Vivariums,
Proper Gradients & UVB.
An enclosure database for 16 reptiles: basking temps, UVB requirements, humidity bands, and minimum enclosure sizes — grouped by habitat type. Free, no sign-up.
Thermal Gradient Principle
Reptiles cannot thermoregulate without a distinct hot basking spot and cool retreat zone.
Ferguson Zone UVB Index
T5 linear tubes delivering specific UVI indexes to synthesize Vitamin D3 and prevent MBD.
Substrate & Moisture Safety
Arid loose sand impaction risks versus bio-active humidity retaining tropical mixes.
ReptiHabitat Profiles
Bearded Dragon
Australia's beloved agamid: docile, diurnal, and the most UVB-dependent popular pet — husbandry is everything.
Uromastyx
North African spiny-tails run the hobby's hottest basking zones and lowest humidity — desert specialists in every sense.
Leopard Gecko
The classic beginner gecko: ground-dwelling, insectivorous, and the veteran of the great UVB debate — now generally settled toward low-output UVB.
Ball Python
West African ground python: famously shy, famously picky about humidity and security — husbandry is mostly psychology.
Crested Gecko
New Caledonia's rediscovered (1994) gecko: arboreal, frugivorous, and famously intolerant of heat — cooler is safer.
Gargoyle Gecko
Rhacodactylus auriculatus: New Caledonian, semi-arboreal, more insectivorous than cresties, and famous for a bolder personality.
Red-Eared Slider
The classic turtle: hardy, omnivorous, and chronically undersized-housed — adults need 100+ gallon setups or ponds.
Chinese Water Dragon
Southeast Asian water dragons: arboreal swimmers needing vertical space, 80% humidity, and deep water — the vivarium challenge.
African Fat-Tailed Gecko
The leopard gecko's forest cousin: same gentle temperament, same belly-heat preference, higher humidity bands.
Kenyan Sand Boa
East African sand boas: fossorial (burrowing) snakes that live IN their substrate — deep aspen is the whole enrichment plan.
Leopard Tortoise
African grazing tortoise: herbivorous, sun-loving, and the classic "lives longer than the owner's house" pet.
Corn Snake
The American rat snake that introduced millions to reptiles: hardy, docile, and genuinely beautiful in dozens of morphs.
California Kingsnake
The desert rat snake: bulletproof husbandry, bold personality, and the famous kingsnake superpower — immunity to rattlesnake venom and a taste for other snakes.
Axolotl
The Mexican neotenic salamander: permanently aquatic, famously regenerative, and heat-intolerant — the anti-tropical pet.
Russian Tortoise
Central Asian steppe tortoise: small for a tortoise, extremely hardy, herbivorous, and a burrower that needs deep substrate or outdoor pens.
