In the wild these lizards are primarily nocturnal, remaining in burrows during the day to emerge at dusk and for part of the night. Vivariums with a large floor space of at least 150 x 90 x 60 cm are necessary. Gila monsters do best in plain cages with a sand substrate. Provide suitable rocks and retreats for the lizards. A thermostatically controlled ceramic heat source or alternatively a spotlight can provide heating with the appropriate wattage. Captive Gila will enter a low dish of water and soak there for long periods.
