Overview

  • 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.

A good fit for

  • Keepers wanting an active, affordable display lizard
  • People happy to watch rather than handle
  • Naturalistic, planted-vivarium enthusiasts
  • Those wanting a small diurnal insectivore

Common mistakes to avoid

  • Housing two males together (constant fighting)
  • Bare tanks without plants and climbing cover
  • Missing UVB, causing metabolic bone disease
  • Relying on a water bowl instead of misting
