- Can use a real water feature — natural swimming behavior
- Smaller commitment than green iguanas

- Snout-rubbing is common in inadequate enclosures

Frequently asked questions
How big do Asian water dragons get?
Males 36 inches including tail; females 24 inches. About 2/3 the size of an adult green iguana.
How long do Asian water dragons live?
10-15 years with proper care. Some individuals exceed 18 years.
Do water dragons need a swimming pool?
Yes — a water feature deep enough to soak and submerge improves welfare significantly. They use water for drinking, soaking, and as a stress refuge.
Are Asian water dragons handleable?
Variable. Some captive-bred individuals tolerate moderate handling. Wild-caught animals rarely tame and should not be bought.
Why does my water dragon have a sore nose?
Snout-rubbing against glass is a classic sign of inadequate enclosure size. The fix is a bigger enclosure with visual barriers and arboreal cover.
