Green Anole

Overview

Green anoles are small, active, day-active lizards from the southeastern United States ¹². They are often treated as starter reptiles, but they need proper lighting, a temperature gradient, humidity and good nutrition like any other lizard ¹. They are display animals more than pets to handle ¹². With good care they live four to eight years ¹. The shorter two to four years often quoted reflects typical rather than best-case care ².

Natural history

Green anoles live in shrubs, gardens, walls and fences across the southeastern US ²³. They are excellent climbers that spend much of their time in vegetation hunting insects ¹². They switch between bright green and brown with temperature, stress, activity and social signals. Color change alone is not a sign of illness ¹. Males are slightly larger and display a red throat fan, or dewlap, especially during the breeding season ².

Enclosure

• Size. At least 18 × 18 × 24 inches (tall) for one adult. Go bigger for more than one ¹. A 2 × 2 × 2 ft screen enclosure is ideal for a small group ².
• Furnishings. Plenty of branches, vines, cork bark and dense live or artificial plants, with a branch close to the basking light ¹². Use only herbicide- and pesticide-free live plants ².
• Hides. At least two: one warm, one cool ².
• Security. Anoles are escape artists, so use tight doors and a secure screen top ¹.
• Groups. Females can often live together with enough space and visual barriers. Never house two adult males together: they fight, sometimes to serious injury or death ¹².

Temperature & lighting

Use digital thermometers and an infrared thermometer for surfaces. Never use a heat rock ¹.

UVB is one of the most important parts of anole care. Use a linear T5 HO tube (about 5–6% UVB) across much of the enclosure on a 12-hour cycle, and replace it about every 12 months. Compact coil UVB bulbs are not recommended as the main source ¹.

Humidity

Keep humidity between 60 and 80%, with daily misting, live plants, a moisture-holding substrate and good airflow ¹. Many anoles drink droplets off leaves rather than from a dish, so mist daily, but keep a shallow water dish available too ¹.

Substrate

Use fertilizer-free topsoil, coconut fiber, cypress mulch or a bioactive mix ¹. Avoid sand, calcium sand, walnut shell, gravel, and cedar or pine shavings ¹.

Diet & supplementation

Anoles eat only insects ¹.

• Prey. Crickets, small dubia roaches, black soldier fly larvae, silkworms, hornworms and flies. Mealworms and waxworms are occasional treats only ¹.
• Size. Never larger than the space between the eyes ¹.
• How often. Juveniles daily, adults three to five times a week ¹.
• Supplements. Gut-load insects for 24 hours. Dust with phosphorus-free calcium at most feedings and a reptile multivitamin once a week ¹. Use calcium with vitamin D3 only on your vet's advice ¹.

Handling & temperament

Frequent handling stresses anoles ¹. When you must move one, go slowly and avoid grabbing the tail. Anoles drop their tails when frightened, and the regrown tail is different and costs the lizard a lot of energy ¹. Wash your hands afterwards, as reptiles can carry Salmonella ⁴.

Health

Common issues ¹

• Metabolic bone disease without UVB and calcium.
• Internal parasites, dehydration and stuck shed. Never pull off stuck shed; constricting shed on toes and tail needs a vet.
• Mouth and respiratory infections.
• Burns, injuries and egg binding in females.

When to see a vet

Tree of Life recommends a wellness exam every 6 to 12 months and a yearly fecal test ¹. Go sooner if your anole ¹⁵:

• Stops eating for more than a week or loses weight.
• Has trouble climbing, or breathes with its mouth open or wheezes.
• Has a swollen jaw or limbs, or stuck shed on its toes.
• Has trouble laying eggs, or has been injured.

Breeding overview

Females lay eggs, and egg binding is one of the problems vets see in pet anoles ¹³. Keep only one male per enclosure ¹².

Legal & ethics

Most green anoles in the pet trade are still wild caught, though they have been bred successfully in captivity ². Ask for captive-bred animals, have a fecal test done on any new anole, and never release a pet anole outdoors.
