Species description
Geographical Origin and Habitat:
This species is native to Cuba and the Bahamas, but it has been widely introduced and established in other tropical and subtropical areas, such as Florida, Hawaii, Taiwan, and parts of Central America. It mainly inhabits open areas, forest edges, urban parks, gardens, and rocky areas, preferring to climb on tree trunks, low shrubs, and fences close to the ground.
Taxonomy and Genetics:
Belonging to the family Dactyloidae, Anolis sagrei is a highly adaptable species that displays significant genetic diversity depending on its population of origin. It is a classic example of a trunk-ground ecomorph, having evolved to exploit the lower to middle layers of vegetation. Several wild subspecies exist, but the Cuban variant is the most common in captivity.
Behavior and Habits:
It is a diurnal, highly active, and territorial reptile. Males defend their territory vigorously through ritualized displays like push-ups and extending their bright orange-red throat fan (dewlap). They are agile climbers but spend a significant amount of time on the ground or low branches hunting for insects, showing a very alert temperament.
Morphology:
It has a slender build with long hind legs and toe pads equipped with microscopic lamellae that allow them to climb smooth surfaces. Males reach a total length of about 18-20 centimeters (including the tail), while females are significantly smaller (12-15 cm). Males also feature a small dorsal crest along their back, which they can raise when excited.
Care, breeding and tankmates
Terrarium Setup:
A single male or a pair requires a vertically oriented terrarium of at least 50x40x60 cm. The interior should be furnished with numerous climbing branches of various diameters, sturdy live plants (such as Pothos and Snake Plants), and cork bark for shelter. The ideal substrate is a bio-active mixture of coconut fiber, peat moss, and sphagnum moss topped with leaf litter.
Lighting and Heating:
Providing a UVB light source (5.0% UVB lamp) turned on for 10-12 hours a day is essential for vitamin D3 synthesis and calcium absorption. Heating should be supplied by a basking bulb to create a localized hot spot of 30-32°C near the top of the enclosure, while the cool zone should stay around 24-26°C. Nighttime temperatures can drop to 20°C.
Humidity and Hydration:
Average relative humidity in the enclosure should be kept between 60% and 80%. This is achieved by misting the terrarium with dechlorinated water twice daily, preferably in the morning and evening. Anoles rarely drink from water dishes; they prefer to lap up water droplets that gather on leaves and enclosure walls after misting.
Feeding and Supplementation:
They are insectivorous predators. The diet should consist of small live insects such as crickets, fruit flies (Drosophila), small roaches, and occasionally mealworms. Feed items must be dusted with a pure calcium supplement at every feeding, and with a calcium + vitamin D3 supplement twice a week to prevent bone diseases.
Compatibility:
Males are highly territorial and must NEVER be housed together, as they will fight to the death. A single male can be housed with one or two females, provided the enclosure is large enough and has plenty of visual barriers (dense foliage) to allow the females to hide from the male's persistent advances.
Health and Common Diseases:
The most common health issue is Metabolic Bone Disease (MBD), caused by insufficient UVB exposure or lack of calcium supplementation. Other risks include internal parasites and respiratory infections caused by low temperatures or inadequate air circulation. Always ensure the terrarium has proper ventilation screens to prevent stagnant air.

The catalog's scalar value is 7.5 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 7.5 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
