Dumeril's monitor enclosure & bioactive setup
Give one adult at least 240 × 120 × 150 cm (94 × 47 × 59 inches). Best kept alone. This species suits a humid terrestrial bioactive build.
- Leaf litter2 cm
- Jurassic ABG Terrarium Mix12 cm
- Base layer – packed coco fibre13 cm
- Drainage – clay bio balls3 cm
Deep, moist soil is what holds humidity in this build – much better than thin bedding, especially through Canadian winters. This species digs, so give it 25 cm (10 in) of substrate in total. Only the top 12 cm needs to be bioactive soil; the 13 cm underneath can be cheaper coco fibre, dampened and packed firm.
Temperature: Basking 45–50°C, ambient 28°C. Humidity: 70–90%. UVB: Required.
What does a dumeril's monitor eat?
Carnivore – crabs, snails, roaches, whole prey. Juveniles daily, adults 3–4 times a week.
Handling, temperament & health
Often calm once settled.
Health watch: Parasites in imports and obesity.
