The Ackie Monitor (scientific name Varanus acanthurus) is one of the most popular small monitor lizards in the reptile-keeping world. Native to the dry, rocky regions of northern Australia, this species combines the curiosity and intelligence of larger monitors with a more manageable size and temperament. Whether you’re a beginner reptile lover or an experienced herpetologist, the ackie monitor lizard makes an excellent choice due to its fascinating behavior, striking appearance, and adaptability in captivity.
Origin and Habitat of the Ackie Monitor
The Ackie Monitor hails from Australia’s arid outback, thriving in desert-like conditions filled with rocks, logs, and burrows. This environment has shaped its unique physiology short, sturdy limbs, a spiny tail for defense, and a reddish-brown or yellow coloration that blends with its surroundings. There are two main types: the Red Ackie Monitor (V. acanthurus acanthurus) and the Yellow Ackie Monitor (V. acanthurus brachyurus). Both are similar in care but differ slightly in color intensity.
Size and Lifespan
An Ackie Monitor typically reaches 2 to 2.5 feet in total length, making it a medium-sized lizard that’s much easier to manage than giants like the Savannah or Water Monitor. With proper care, they can live up to 15–20 years in captivity. Their relatively small size, combined with a long lifespan, makes them a rewarding reptile companion for those who can provide the right setup.
Housing and Enclosure Setup
Creating the right enclosure is essential for keeping your Ackie Monitor healthy. Since they are active burrowers and climbers, space and enrichment are key. A 4x2x2-foot enclosure is the minimum recommended for one adult. Include a deep substrate mix (at least 10–12 inches) of soil and sand to allow for natural digging behavior.
A basking spot should reach 120–150°F (49–65°C), while the cooler end should stay around 80°F (27°C). Use high-quality UVB lighting to support vitamin D3 synthesis, which is critical for bone health. The enclosure should also include rocks, branches, and hides to mimic their natural habitat.
Diet and Feeding Habits
The Ackie Monitor is an insectivore, with a diet that includes crickets, roaches, mealworms, and the occasional pinky mouse. In captivity, it’s crucial to dust insects with calcium and vitamin supplements to maintain nutritional balance. Ackies have fast metabolisms and hearty appetites, so feeding them every other day is ideal for adults.
Offering a variety of live foods encourages their natural hunting instincts and keeps them active. Clean water should always be available, though they obtain most hydration from their prey and occasional misting.
Temperament and Behavior
One of the most appealing qualities of the Ackie Monitor is its friendly and inquisitive temperament. While some reptiles are shy or defensive, Ackies are known for being curious and relatively easy to tame with consistent handling. They are intelligent creatures that can recognize their owners and even respond to feeding routines.
These monitors display fascinating behaviors basking, burrowing, and tongue-flicking to sense their surroundings. Observing an Ackie Monitor is like watching a small dinosaur in action, which is a big part of their charm.
Health and Maintenance
A healthy Ackie Monitor shows clear eyes, smooth scales, and an active appetite. Common health issues include metabolic bone disease, often caused by poor lighting or calcium deficiency, and respiratory infections from incorrect humidity levels. Keeping the enclosure dry, clean, and warm helps prevent most problems.
Regular vet check-ups and a proper diet ensure your Ackie lives a long and active life. Avoid overfeeding, as obesity can become an issue for monitors in captivity.
Breeding the Ackie Monitor
Breeding Ackie Monitors can be rewarding but requires preparation. Provide a nesting area with deep, moist substrate for females to lay eggs. Incubate the eggs at around 85°F (29°C), and hatchlings will emerge after 90–120 days. Young Ackies should be housed separately and fed small insects multiple times daily until they grow stronger.
Why the Ackie Monitor is a Great Pet
The Ackie Monitor is often described as the perfect “beginner monitor.” Its size, intelligence, and manageable care requirements make it suitable for reptile enthusiasts who want the thrill of keeping a monitor without the challenges of larger species.
They’re active during the day, easy to observe, and full of personality. With consistent handling and proper setup, an Ackie Monitor can become surprisingly interactive and trusting, forming a genuine bond with its keeper.

Adult Ackie Monitors reach 24–30 inches (2–2.5 feet) in total length, including the tail.
4. Do Ackie Monitors need UVB lighting?
Absolutely. Proper UVB lighting is essential to prevent bone disease and support calcium absorption.
5. How long do Ackie Monitors live?
With the right care, they can live between 15–20 years in captivity.
6. Can multiple Ackie Monitors live together?
Generally, it’s best to keep them singly unless you are an experienced keeper aiming to breed them. Males can be territorial.
