Ackie Monitor Resource Hub

Complete ackie monitor care guide with 150°F+ basking setup, 12-18 inch deep substrate requirements, diet, handling, and why ackies are the best first monitor.

Lifespan

15-20 years

Origin

Australia (arid scrublands and rocky outcrops)

Habitat & Setup

Tank Size

4x2x2 feet minimum (roughly 120 gallons) — larger is always better

Substrate

12-18 inches of 60/40 organic topsoil and sand mix, packed firmly and kept slightly moist at the bottom

150-170°F surface temperature

Cool Side

75-80°F

Night

70-75°F

Humidity: 60-80% in burrows

Achieved through deep, slightly moist substrate — surface can be dry while burrow humidity stays high

Diet & Feeding

Insectivore/Carnivore

Schedule

Juveniles: daily; Adults: every other day with occasional fasting days

Supplements

Calcium with D3 every feeding for juveniles, every other feeding for adults; multivitamin 1x/week

Recommended Gear

Habitat Gear

Zen Habitats 4x2x2 PVC Reptile Enclosure
View on Amazon

Minimum recommended size for an adult ackie — PVC retains heat far better than glass, which is critical for reaching 150°F+ basking temps

Heating

Philips 90W PAR38 Halogen Flood Light
View on Amazon

Halogen flood bulbs produce the intense focused heat needed for 150°F+ basking surfaces — far more effective than standard basking bulbs for monitors

Lighting

Zoo Med ReptiSun 10.0 T5 HO UVB Lamp
View on Amazon

Strong UVB output essential for calcium metabolism — T5 HO provides adequate UVB even through the deep substrate zone

Monitoring

Etekcity Infrared Temperature Gun
View on Amazon

Absolutely essential for measuring basking surface temperatures — ambient thermometers cannot read the 150-170°F surface temps ackies need

Digital Thermometer Hygrometer Combo
View on Amazon

Monitor both temperature gradient and burrow humidity — place probes at basking surface and inside the substrate layer

Feeding

Rep-Cal Calcium with Vitamin D3
View on Amazon

Fine powder calcium supplement for dusting feeder insects at every feeding — critical for fast-growing juvenile monitors

Frequently Asked Questions

Ackie monitors are intermediate-level reptiles. Their care isn't difficult once the enclosure is set up correctly, but the initial setup is more demanding than most pet reptiles. You need extreme basking temperatures (150-170°F surface), 12-18 inches of deep substrate, and a large 4x2x2 foot minimum enclosure. Once these are dialed in, daily care is straightforward — feeding, water changes, and spot cleaning.
