Give them room
Modern care guides recommend at least a 40-gallon (about 90 × 45 × 45 cm) enclosure for an adult. More floor space means a better temperature gradient and more room to explore.
Heat with a gradient, and always use a thermostat
Leopard geckos regulate their temperature by moving between warm and cool areas. Heat one end of the enclosure with a heat mat or an overhead heat source, and leave the other end cooler.
Every heat source should run through a thermostat. It stops overheating and is the single most important safety item in the setup. Check temperatures with a digital thermometer.
Three hides, minimum
Provide a warm hide, a cool hide, and a humid hide (a hide with damp moss inside) to help them shed. Add climbing branches and plants for enrichment.
Lighting and feeding
A day/night light cycle helps, and many keepers now add low-level UVB. Feed live insects and dust them with a calcium supplement. Use shallow dishes so insects can't escape, and keep a water dish available at all times.
