Ackie monitors (spiny-tailed monitors) run hot — a fast metabolism paired with an active foraging lifestyle means they need frequent, insect-heavy meals, more like a small monitor's natural hunting pattern than a typical pet lizard's feeding schedule.
What They Eat
Dubia roaches are the best staple for Ackies — they don't burrow into substrate the way mealworms can, so they stay available for the monitor to hunt down, which matters for a species that thrives on foraging. Superworms work well as an occasional higher-fat addition.
How Often to Feed
- Hatchlings & juveniles: Daily, as many appropriately sized insects as consumed in one active foraging session.
- Adults: Every 1–2 days, scattered or hidden in substrate/leaf litter to encourage natural hunting behavior.
Gut-Loading & Dusting
Given how much this species eats relative to its size, gut-load quality compounds fast. Dust with calcium at most feedings, calcium with D3 weekly without UVB. See our gut-loading guide.
Common Mistakes to Avoid
Ackies are voracious — it's easy to overfeed a species this active-looking. Body condition, not appetite, should guide portion size.
