Monitor Lizard Care Guide: Everything You Need to Know

Monitor lizards are among the most intelligent and impressive reptiles in the hobby. From the compact ackie monitor to the powerful savannah monitor, these varanids are active, curious, and capable of forming genuine bonds with their keepers. However, they require significant commitment in terms of space, diet, and enrichment. Here's your complete guide!

🏠 Choosing the Right Species

For beginners, the Ackie Monitor (Varanus acanthurus) is highly recommended — smaller (24–28"), manageable, and very handleable. The Savannah Monitor is also popular but grows larger (3–4 feet) and requires more space and experience.

🏠 Setting Up the Enclosure

Monitors need large, enriched enclosures with deep substrate for burrowing:

• Ackie Monitor: Minimum 4' x 2' x 4' (tall for climbing)
• Savannah Monitor: Minimum 6' x 4' x 4' for adults
• Substrate depth: 12–24" of a bioactive or sandy loam mix for burrowing
• Basking spot: 130–150°F (surface temp) — monitors need extreme heat to digest properly
• Ambient warm side: 90–95°F; cool side 75–80°F
• UVB lighting: High-output 10.0 UVB — essential for health
• Provide hides, climbing branches, and foraging opportunities

🍽️ Nutrition & Feeding

Monitors are carnivores with high protein needs:

• Ackie Monitors: Primarily insects — dubia roaches, crickets, mealworms, and occasional pinky mice
• Savannah Monitors: Insects (dubia roaches, superworms), snails, whole prey (mice, chicks), and eggs
• Avoid feeding primarily rodents — leads to obesity and fatty liver disease
• Dust feeders with calcium at every feeding; multivitamin weekly
• Feed juveniles daily; adults 3–5 times per week

🤝 Handling & Enrichment

Monitors are highly intelligent and benefit greatly from environmental enrichment — foraging puzzles, novel objects, and varied terrain. Regular, calm handling from a young age produces very tame animals. Always support their full body weight and avoid sudden movements.

💊 Health & Wellness

Common health issues include obesity (from rodent-heavy diets), metabolic bone disease, respiratory infections, and parasites. Annual vet check-ups with a reptile-experienced veterinarian are essential. Watch for lethargy, swollen limbs, wheezing, or refusal to eat.
