Jackson’s chameleons, with their exotic horns and incredible color-changing abilities, have become hugely popular reptile pets. Their entrancing appearance and seemingly gentle nature make them appealing for first-time chameleon owners.
But proper Jackson’s chameleon care requires some very specific housing, feeding, and health needs. Beginners need to fully research their care ahead of getting one of these fascinating pets.
With this complete Jackson’s chameleon beginners care guide, new owners will learn everything required for keeping healthy, happy pet Jackson’s chameleons.
Jackson’s Chameleon Care Background
Jackson’s chameleons, scientific name Chamaeleo jacksonii or Chamaeleo jacksonii xantholophus or also as Trioceros jacksonii, originate from the mountains of Kenya and Tanzania in East Africa.

They are also called Jackson’s horned chameleons and Jackson’s three-horned chameleons due to the exotic-looking horns protruding from their heads.
These arboreal lizards live high up in trees and have several key adaptations for climbing and camouflage. Their specialized feet, prehensile tail, independently rotating eyes, and color-changing abilities all help them thrive in their natural habitat.
A. Overview of the Species
Belonging to the Chamaeleonidae family, Jackson’s chameleons are medium-sized lizards that can grow up to 10-14 inches in length.
They are known for their vibrant colors, which range from shades of green, yellow, and blue to rusty browns and grays.
These colors are not only visually stunning but also serve as a means of communication and camouflage in their natural habitat.
B. Native Habitat and Range
In the wild, Jackson’s chameleons inhabit the highland rainforests and montane regions of Kenya and Tanzania, typically at elevations between 1,500 and 3,000 meters.
Their native range includes the Aberdare Mountains, Mount Kenya, and the Ngorongoro Conservation Area, among others.
C. Unique Features
One of the most distinctive features of Jackson’s chameleons is their horned casques, which are bony protrusions on their heads. These horns are more pronounced in males and play a role in territorial displays and courtship rituals.
Additionally, Jackson’s chameleons are one of the few chameleon species that give birth to live young, rather than laying eggs.
Of the nine different Chamaeleo chameleon species, Jackson’s is one of the most commonly bred and sold worldwide as pets. Their small size, unique appearance, and supposed docile temperament make them very attractive to reptile enthusiasts, especially beginners.
However, Jackson’s chameleons are not necessarily easy or low maintenance reptiles.
There are several very specific care requirements new owners must get right in order to keep them healthy. Doing thorough research beforehand is crucial.
Choosing and Purchasing a Jackson’s Chameleon
Before acquiring a Jackson’s chameleon, it’s essential to understand the different subspecies, learn how to sex them, and identify signs of a healthy specimen.

Purchasing from reputable breeders is highly recommended to ensure the chameleon’s well-being and authenticity.
A. Subspecies and Variations
There are three recognized subspecies of Jackson’s chameleons:
- Trioceros jacksonii jacksonii (Typical Jackson’s Chameleon)
- Trioceros jacksonii xantholophus (Yellow-crested Jackson’s Chameleon)
- Trioceros jacksonii merumontanus (Mount Meru Jackson’s Chameleon)
Additionally, various color morphs and patterns exist within these subspecies, adding to the diversity of this species.
B. Sexing Chameleons
Determining the sex of a Jackson’s chameleon is important for breeding purposes or if you have a specific preference.
Males typically have larger horns, a taller casque, and a more pronounced bulge at the base of the tail (hemipenal bulge). Females, on the other hand, have smaller horns, a less pronounced casque, and a smaller overall size.
C. Selecting a Healthy Chameleon
When choosing a Jackson’s chameleon, look for signs of good health, such as:
- Clear, bright eyes
- Firm, well-muscled body
- Alertness and responsiveness
- Smooth skin without lesions or discoloration
- Healthy appetite and appropriate weight
D. Reputable Breeders vs. Pet Stores
It’s highly recommended to purchase Jackson’s chameleons from reputable breeders rather than pet stores.
Breeders typically have a better understanding of the species’ care requirements and can provide valuable information about the chameleon’s lineage and history.
Additionally, captive-bred chameleons are more accustomed to captive conditions and less likely to carry parasites or diseases.
Jackson’s Chameleon Enclosure
In the wild, Jackson’s chameleons live high up in trees and come down to the forest floor infrequently. Their housing needs to mimic this arboreal habitat.

Enclosure Type
The best enclosures have plenty of screened and ventilated areas for proper air flow. Glass tanks or terrariums retain too much humidity and do not allow enough air circulation.
Well-ventilated screen, mesh, or wire reptile cages work best for Jackson’s chameleons. Some options include:
- Screen/mesh reptile cages
- Custom-built wire enclosures
- Modified wardrobe cabinets with screen panels
- Screened terrariums
The sides should be primarily mesh for optimal ventilation. Any solid walls or glass should be limited.
Size
Jackson’s chameleons are relatively small, only growing to 8-10 inches as adults. But they are active and need ample space.
For an adult, the minimum enclosure sizes are:
- 2 x 2 x 4 feet for one chameleon
- 3 x 2 x 4 feet for a pair
Bigger is always better if possible. More room allows you to create proper temperature gradients and gives your chameleon room to roam and climb.
Substrate
Since Jackson’s chameleons live arboreally and come to the ground rarely, substrate is not a huge factor. Simple, easy to clean options are best.
- Reptile carpet
- Paper towels
- Sheet moss
- Lizard litter substrates
Avoid loose substrates like sand, bark, or coconut husk that could potentially get caught in their eyes.
Decor & Furnishings
Unlike some reptile pets that spend most of their time on the ground, arboreal Jackson’s chameleons need vertical space to climb and perch.
Provide an abundance of climbing branches, vines, live or artificial foliage, and other perches at various heights inside the enclosure. This allows them to fully exhibit their natural climbing behaviors.
Make sure to use solid, sturdy decor items that can fully support the weight of an adult Jackson’s chameleon without tipping over. Avoid thin, flimsy plastic plants and weak branches.
Live plants help increase humidity levels and provide visual barriers, but do require proper lighting and care themselves. Some good options include pothos, ficus, and hibiscus.

Jackson’s Chameleon Temperature & Lighting
Maintaining the proper environmental conditions is crucial for the health and well-being of your Jackson’s chameleon.
Temperature, lighting, and humidity levels must be carefully monitored and adjusted to mimic their natural habitat.

Basking Spot
Jackson’s chameleons are ectothermic and rely on external heat sources to regulate their body temperature.
They need a focused basking spot reaching 85-95°F (29°C to 35°C) provided by an overhead incandescent or halogen busking bulb or ceramic heat emitter. This gives them a warm place to raise their body temperature throughout the day.
Place the basking lamp above a high perch so the chameleon can get right beneath it if needed. Keep a temperature gun on hand to measure basking spot temps.
Ambient Temperature
The ambient temperature range in the rest of the enclosure should be 70-80°F (21°C and 26.5°C). This gives your chameleon a gradient so they can thermoregulate by moving between warmer and cooler areas as needed.
Use a digital thermometer/hygrometer to monitor ambient temps. The room temperature can help maintain suitable ambient temperatures.
Nighttime Temperatures
At night, temperatures can be allowed to drop about 10°F lower. But should not go below 65°F.
A ceramic heat emitter connected to a reptile thermostat helps maintain appropriate overnight lows if needed.
UVB Lighting
Jackson’s chameleons require UVB light for critical vitamin D3 synthesis and calcium metabolism.
Use a linear tube UVB bulb rated for at least 10% UVB output. Length should be 2/3 the enclosure length. Place the fixture 6-12 inches above the highest basking perch.
Replace UVB bulbs every 6 months, as output declines over time. Provide 10-12 hours per day of UV exposure.
Day/Night Cycle
In addition to heat and UV lighting, Jackson’s chameleons need a proper photoperiod or day/night cycle. Nighttime temperatures should range from 60°F to 70°F (15.5°C to 21°C).
Provide 10-12 hours of daytime light and 12-14 hours of darkness at night. Use timers to regulate the day/night cycle.
Here’s a useful overview table…
