One anole requires a 10 gallon terrarium (18" high with a screened lid). For multiple anoles, use a larger terrarium.
Coconut fiber, moss or bark bedding
Line the habitat with 2-3" of coconut fiber, moss or bark bedding. Remove droppings and spot-clean frequently. Stir the bedding every other week and change every month.
Natural or artificial rocks
Create a hiding place with natural or artificial rocks or wood, and provide live plants and branches for your anole to climb.
Temperature gradient
Anoles require a temperature gradient (warm on top and cool on the bottom). Add thermometer(s) (one on the top and one on the bottom) to measure the temperature, and a hygrometer to measure humidity.
UVB and heat lamp
Reptiles require a 12-hour day/night cycle. Provide your pet with a UVB and heat lamp so that they can properly absorb calcium.
Humidity
Create and maintain humidity by keeping the water dish full, misting your pet and habitat 2-3 times every day, or using an automatic fogger or drip system.

Temperature gradient
Create a cool side and basking spot in the habitat for your reptile.
