The green anole is a small, agile, diurnal lizard native to the southeastern United States, able to shift between green and brown and known for the male's pink throat fan, or dewlap.
It is inexpensive and widely available, but its small size belies genuine husbandry needs.
Anoles are fast, fragile and easily stressed, with a tail that drops when grabbed, so they are best treated as a watch-don't-touch species.
They live only a few years and are often kept poorly in bare tanks.
A well-planted, correctly lit vivarium lets their natural behaviour show.
Housing
House anoles in a tall, well-ventilated, heavily planted vivarium of at least 45x45x60 cm for one or a small group, with abundant branches, vines and foliage for climbing, basking and hiding.
Vertical space and dense cover reduce stress in this arboreal species.
Provide a basking spot of about 28-32C under a heat lamp with a cooler gradient below, and a UVB source, as anoles are diurnal and need it for calcium metabolism and to prevent metabolic bone disease.
Maintain humidity around 60-70% by misting once or twice daily; they drink droplets from leaves rather than from a standing bowl.
Diet
Green anoles are insectivores that eat a variety of small, gut-loaded live insects such as appropriately sized crickets, fruit flies, small roaches and black soldier fly larvae.
Prey should be no wider than the space between the eyes, and active hunting is part of their enrichment.
Dust insects with calcium regularly and with a vitamin/D3 supplement on a measured schedule to prevent both deficiency and excess.
Feed most days, adjusting for body condition.
Mist surfaces so they can drink, since dehydration is common when keepers assume a water bowl is enough for this droplet-drinking species.
Health
A healthy anole is alert, brightly coloured when relaxed, well-muscled and active during the day.
Metabolic bone disease from inadequate UVB or calcium is the most common serious problem, alongside dehydration, stuck shed from low humidity, and stress-related colour darkening and hiding.
Because they are small and secretive, weight loss and illness can be missed, so observe appetite and body condition closely.
A dropped tail regrows imperfectly and is a sign of rough handling.
Persistent dark colour, lethargy, sunken eyes or a soft jaw should prompt a visit to an exotics vet familiar with small lizards.
Temperament
Green anoles are quick, alert and entertaining to watch, with males displaying dewlaps and territorial push-ups.
They are not handling pets; they are easily stressed, dart rapidly and can drop their tails, so interaction should be limited to maintenance and observation.
Socially, males are strongly territorial and must never be housed together, as they fight and display constantly.
A single male with one or more females, or a small group of females, can work in a large, well-planted enclosure with multiple basking and hiding spots, provided you watch for bullying and stress.

Keepers wanting an active, affordable display lizard
Most reptile emergencies are husbandry emergencies first. Before you panic, check the temperatures — but check them with a thermometer, not a hand.
Go now
Open-mouth breathing, or bubbles and mucus at the nose or mouthGo now. Raise the warm end to the top of the species range in transit. Respiratory infection in a reptile is usually already established by the time it is visible, and it advances fast at the wrong temperature.
Now
Prolapse — any tissue protruding from the ventGo now. Keep the tissue moist with clean lukewarm water. Do not push it back in. Exposed tissue dries and dies quickly, and the window for a simple repair is short.
Now
Gaping, gasping, or unable to right itself when gently turned overGo now. Loss of the righting reflex signals a neurological or metabolic crisis.
Now
A burn, or a blackened patch on the belly or sideGo now, and unplug the heat source before you leave. Contact burns from an unregulated mat or an unguarded lamp are among the most common injuries in captive reptiles.

Today
Tremors, twitching, jerky limbs, or a rubbery jawCall today. Note your UVB bulb type and when it was last replaced. Almost always a calcium and D3 problem, and almost always a UVB problem underneath that.
Today
Retained shed over the eyes, or a ring of stuck shed on the tail or a toeRaise humidity and offer a damp hide, then call if it is not clear within a day. A constricting ring cuts off circulation and the digit or tail tip is lost.
Today
Sudden weight loss, or a visibly sunken or triangular body shapeCall today, with the weight history. A reptile that has lost condition has usually been unwell for a while.

Refusing food beyond the species' normal fastCheck what a normal fast looks like for this species before worrying — for several snakes it is weeks, not days. Then log it and book if the fast is unusual for this animal. Feeding anxiety drives more unnecessary vet visits than any other reptile question, and also masks the fasts that genuinely matter.
Check the guide first
Before any non-emergency call, write down the four numbers a vet will ask for: the thermostat probe reading, the warm-end air temperature, the cool-end air temperature, and the hottest accessible surface. Surface temperature can run well above the air above it.
This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a green anole eat that?
Reptile diets split hard by species. An insectivore and a grazing tortoise share almost nothing, so check the species guide as well as this list.

That food is not on our list. Reptile diets are narrower than they look — check the species guide, and ask an exotics vet before offering anything unfamiliar.
Dust feeders with a calcium supplement to the schedule in the species guide. A reptile can be eating well and still be starving of calcium.
