Habitat Gear
Minimum recommended size for an adult ackie — PVC retains heat far better than glass, which is critical for reaching 150°F+ basking temps
Heating
Halogen flood bulbs produce the intense focused heat needed for 150°F+ basking surfaces — far more effective than standard basking bulbs for monitors
Lighting
Strong UVB output essential for calcium metabolism — T5 HO provides adequate UVB even through the deep substrate zone
Monitoring
Absolutely essential for measuring basking surface temperatures — ambient thermometers cannot read the 150-170°F surface temps ackies need
Monitor both temperature gradient and burrow humidity — place probes at basking surface and inside the substrate layer
Feeding
Fine powder calcium supplement for dusting feeder insects at every feeding — critical for fast-growing juvenile monitors
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.
