Dumerils Monitor

Subadult  Monitors (Varanus dumerilii) are at a fascinating transitional stage—no longer hatchlings, but not yet full-grown adults. Native to Southeast Asia, these semi-aquatic, arboreal lizards are known for their striking appearance, intelligence, and complex care needs. Let’s break down what makes subadults unique and how to care for them properly 🦎:

Monitor Lizard Care: Subadult Stage

🧬 Physical Traits of Subadult Dumeril’s Monitors

• Size: Typically between 18 to 36 inches (45–90 cm) in length.
• Coloration: Still retain some of their juvenile vibrancy—often with orange or tan markings—but beginning to darken toward adult tones.
• Build: Slender but muscular, with sharp claws and a laterally compressed tail for swimming and climbing.
• Behavior: More active and curious than hatchlings, but still skittish and easily stressed.

🛠️ Enclosure Setup for Subadults

• Minimum Size: At least 6′ L x 3′ W x 4′ H, with vertical space for climbing and a water basin for soaking.
• Substrate: Moisture-retaining mix like cypress mulch, coconut coir, or sphagnum moss.
• Features: Include branches, hides, and a large water container—these monitors love to swim and burrow.

🌡️ Environmental Needs

• Temperature Gradient:
  • Basking spot: 110–120°F (43–49°C)
  • Cool side: 80–85°F (27–29°C)
  • Night drop: 68–75°F (20–24°C)
• Humidity: Maintain 70–80% with daily misting and proper ventilation.
• Lighting: UVB is essential—use high-output bulbs like Arcadia 12% or Zoo Med Reptisun T5 HO.

🍽️ Diet & Feeding

• Staples: Gut-loaded insects (crickets, roaches), quail eggs, small rodents, and occasional fish.
• Feeding Frequency: 4–5 times per week for subadults.
• Supplements: Calcium with D3 and multivitamins 2–3 times weekly.
