Frequently asked questions
How big do Ackie monitors get?
Adults reach 24-28 inches including tail. Significantly smaller than savannah, Nile, or water monitors.
How long do Ackie monitors live?
15-20 years with proper husbandry. Some individuals exceed 25 years.
Are Ackie monitors good pets?
Yes for keepers ready for a medium-sized enclosure, high basking temperatures, and varied feeding. They're the most accessible monitor for serious hobbyists.
Do Ackie monitors need UVB?
Yes — mandatory. T5 HO 10-12% across most of the enclosure length. Without proper UVB, MBD develops.
Can you handle an Ackie monitor?
Many individuals tame with consistent interaction and become handleable. Acclimation takes months, not days. Bites and scratches are possible — supervised contact only.
