Enclosure Size
Bigger than the standard 20 gallon long.
The minimum recommended size in advanced husbandry circles is now 36"x18"x18" (a 40 gallon breeder equivalent), with 48"x24"x24" considered better.
You need physical space to create microclimate gradients.
Humidity Gradient (Not Low Humidity)
Stop chasing a single 30% humidity reading.
Build a gradient:
• Hot dry zone: 30–40% ambient
• Cool middle zone: 40–60%
• Humid burrow zone: 60–80% inside a humid hide or under hardscape
• Seasonal monsoon cycling: Increase humidity for 1–2 weeks every few months to mimic rainy seasons
Temperature Gradient
• Basking surface: 90–95°F (32–35°C)
• Cool side: 70–75°F (21–24°C)
• Nighttime drops: Allow temperatures to drop to 65–70°F (18–21°C) at night
• Seasonal cooling: Reduce temperatures slightly in winter to mimic natural cycles
A nighttime temperature of 70°F is not an emergency. It’s normal.
Substrate
A bioactive substrate that holds burrows, drains properly, and supports microfauna.
The 60% topsoil + 30% sand + 10% clay mix or a quality pre made bioactive substrate works well.
Paper towels are not a long term solution. They prevent every natural behavior the gecko has evolved to perform.
Hardscape and Vertical Structure
Wild leopard geckos climb. Provide:
• Rocky stacked structures they can climb on and around (anchor securely)
• Cork bark hides at multiple heights
• Branches and ledges for vertical access
• Leaf litter on the substrate floor
• Crevices they can retreat into
Carbonized cork bark is particularly effective because it mimics the rocky stone wall crevices of their natural habitat while supporting bioactive ecosystems.
Water Access
A water dish is non negotiable.
But also consider:
• Light misting in the morning to provide dew (target hardscape, not the gecko)
• Multiple water sources at different points in the enclosure
• Humid hide always available for hydration retreat
Cleanup Crew
A bioactive cleanup crew of Folsomia candida (temperate springtails) and Porcellio scaber or Armadillidium vulgare (isopods) processes waste and replicates the biological matter rich floor of wild habitat.
Diet Adjustments
We’re not recommending feeding lizards to your gecko. But:
• Increase variety beyond crickets and mealworms. Dubia roaches, hornworms, silkworms, and black soldier fly larvae offer better nutrition
• Take supplementation seriously. Calcium with D3, multivitamin, on appropriate schedule
• Consider low output UVB (Arcadia ShadeDweller or 5.0 T5) for D3 synthesis. The leopard geckos don’t need UVB claim is being increasingly challenged.
