Asian water monitor enclosure & bioactive setup
Give one adult at least 360 × 180 × 180 cm (142 × 71 × 71 inches). Best kept alone. This species suits a semi-aquatic (paludarium) bioactive build.
- Leaf litter2 cm
- Jurassic ABG Terrarium Mix12 cm
- Base layer – packed coco fibre18 cm
- Drainage – clay bio balls4 cm
Quantities assume about half the floor is land. The water half needs a filter and regular partial water changes. This species digs, so give it 30 cm (12 in) of substrate in total. Only the top 12 cm needs to be bioactive soil; the 18 cm underneath can be cheaper coco fibre, dampened and packed firm.
Temperature: Basking 50°C+, ambient 28°C. Humidity: 70–90%. UVB: Required.
Some Canadian provinces and many municipalities restrict or ban this species. Check your local bylaws and any provincial permit rules before buying.
