Introduction to the Timor Monitor
The Timor monitor, also known as the Spotted Tree Monitor, is a small species of monitor lizard native to the island of Timor in the Indo-Australian Archipelago.

Origin and Natural Habitat
The Timor monitor is native to the tropical jungle on the island of Timor, which is shared between Indonesia (West Timor) and the sovereign state of Timor-Leste (East Timor). In the wild, these lizards inhabit hot, humid jungles with numerous trees to climb and foliage to hide in. They have also been known to adapt to climbing rock walls and hiding in crevices in areas where forests have been cleared.
Appearance and Physical Characteristics
The Timor monitor has a classic monitor lizard appearance, with a sleek body, long neck, and elongated head. Its prehensile tail can account for as much as two-thirds of its length, and it has five long, sharp-clawed toes, sharp teeth, and a long tongue. The coloration of the Timor monitor varies from black, dark gray, or dark green, with irregular, transverse bands of golden-yellow or occasionally bluish eye spots. These bands become rings on the tail, and their bellies are straw-colored with numerous small, dark speckles.
Males and females look extremely similar, making it difficult to distinguish between the two. Timor monitors are diurnal and arboreal, meaning they are active during the day and prefer to spend their time in trees. They are known to be timid creatures, hiding at the slightest sign of danger.
Size and Lifespan
Newly hatched Timor monitors measure approximately five inches long and experience rapid growth throughout their juvenile years, eventually reaching their adult size of 16 to 24 inches. In captivity, it’s possible for Timor monitors to reach up to 30 inches in length. These reptiles have a relatively long lifespan, with the potential to live up to 20 years in captivity when provided with proper care.
Temperament and Behavior
Timor monitors are known for their solitary, shy, and nervous demeanor. They require plenty of hiding spots within their enclosure to feel secure and are best kept on their own. Males should never be housed together, as they will engage in aggressive combat.
While wild-caught specimens tend to be highly nervous around humans, those raised in captivity may tolerate some handling. Timor monitors are unlikely to attack humans with their teeth, claws, or tails. However, they may defecate on perceived threats and will generally attempt to escape and hide from danger. Due to their highly intelligent nature, these lizards thrive in stimulating environments with ample opportunities for mental and physical exercise.
Housing and Tank Setup
To ensure the health and happiness of your Timor monitor, it’s essential to provide an enclosure that closely replicates its natural environment. This includes a hot, humid, and leafy jungle-like setting with ample vertical space and climbing opportunities.
Enclosure Size
Although hatchlings can be temporarily housed in 20-gallon tanks, it’s best to start them in an adult-sized enclosure to minimize stress from frequent habitat changes. The minimum enclosure size for an adult Timor monitor is 240 gallons, with an emphasis on vertical space to accommodate their arboreal preferences.
Lighting
Timor monitors require a consistent 12-hour light/dark cycle, which can be achieved using a timer. UVB lighting is essential to prevent health issues and should be housed in a reflector on the same side of the enclosure as the heat lamp. Additionally, plant grow lights can be beneficial for these lizards, as they mimic the natural sunlight they would receive in the wild.
Temperature and Humidity
Daytime temperatures within the enclosure should range between 79 and 90°F, with nighttime temperatures between 71 and 75°F. Smooth transitions between daytime and nighttime temperatures are crucial to prevent chilling. A basking spot with temperatures between 120 and 130°F should be provided, ideally using halogen heat bulbs positioned about one foot from the basking surface. The enclosure’s temperature should be monitored using a digital probe thermometer.
Humidity levels should be maintained between 70 and 85%, with occasional peaks around 90%. Automatic misting systems can be used to mist the enclosure twice daily when the lights are off, typically around dawn and dusk. If additional humidification is needed, a cool mist humidifier controlled by a humidistat can be utilized at night. Use distilled or disinfected water to prevent contamination, and measure humidity levels with a digital hygrometer.
Substrate and Decoration
Hatchlings can be housed on paper towels or astroturf, while juveniles and adults require a more naturalistic substrate. A mixture of mulch, coco peat, small-grained gravel, and jungle soil is ideal, with a depth of at least one foot to accommodate their burrowing tendencies. Chemical-free leaf litter can be added to enrich their environment further.
Provide plenty of sturdy branches and vines for climbing, as well as multiple hiding spots, such as cork rounds and live or artificial plants. A large, well-hidden water tub should also be incorporated into the enclosure, allowing your Timor monitor to soak and play as desired.
Cleaning and Maintenance
Regular cleaning is vital to maintain a healthy environment for your Timor monitor. Replace the substrate entirely every three to four months, and remove feces, urates, and contaminated substrate daily. Change the water in their tub as needed, and clean the container with a reptile-safe disinfectant. Always remove your Timor monitor from the enclosure before cleaning to prevent stress and potential injury.
Diet and Feeding
Timor monitors are primarily insectivorous, meaning their diet consists mainly of insects. A wide variety of live insects should be provided, with gut-loading to ensure maximum nutritional value. Feed juveniles daily, and adults three to four times per week, offering as much as they can consume in five to ten minutes.
Appropriate food items include grasshoppers, crickets, roaches, fly larvae, mealworms, beetle larvae, adult darkling beetles, silkworms, and centipedes. Dust insects with vitamin and calcium supplements, especially for younger monitors. Adult Timor monitors may occasionally be offered a pinkie mouse, feeder guppy, or raw egg, but take care to avoid overfeeding and obesity.
Handling and Interaction
While captive-bred Timor monitors may tolerate some handling, excessive handling can lead to stress. Handle them for short periods, starting when they are hatchlings, and use feeding tweezers to build trust. Due to their timid nature, Timor monitors are not recommended for beginners or children.
Common Health Issues
Timor monitors are generally hardy creatures but may experience health issues such as obesity, calcium deficiency, digestive problems, or infections if not properly cared for. To prevent these issues, provide a balanced diet, calcium supplements, UVB lighting, a clean enclosure, and proper temperature and humidity levels. Minimize handling to reduce stress on your Timor monitor.
Breeding
Breeding Timor monitors in captivity can be achieved by simulating the natural conditions that trigger mating, such as decreasing temperatures and increasing humidity. A gravid female will lay five to 11 eggs in a dug-out pit, which will hatch after approximately 90 to 120 days, depending on the average temperature. Hatchlings grow quickly and reach sexual maturity around five to six years of age.
Choosing and Buying a Timor Monitor
When purchasing a Timor monitor, seek out a reputable breeder and expect to pay around $200 for a healthy specimen. Timor monitors are an excellent choice for reptile enthusiasts with intermediate experience who appreciate a small, beautiful monitor lizard that requires minimal human interaction. However, those seeking a more sociable dwarf monitor may wish to consider an ackie or mulga monitor instead.
In conclusion, the Timor monitor is a fascinating and unique reptile that can thrive in captivity with proper care and attention. By providing a suitable habitat, balanced diet, and appropriate environmental conditions, you can ensure that your Timor monitor lives a healthy and happy life.
