Getting there
Fast in the first two years
They reach most of their adult size quickly, so the housing requirement arrives early.
Males develop larger crests and jowls
Alongside the greater length.
What that size means in practice
Tall, planted, and with water
A semi-arboreal semi-aquatic lizard needs height, climbing structure, a water section and high humidity. Commonly cited adult enclosures are around 4 by 2 by 4 feet or larger.
Most of the length is tail, which still needs room
A three-foot animal in a short enclosure cannot turn or climb properly even if it technically fits.
Common questions
How big do Asian water dragons get?
Males reach around 3 feet in total length and females around 2, with roughly two thirds of the length being tail.
What kind of enclosure does an Asian water dragon need?
Tall and planted with climbing structure, a water section large enough to submerge in, and high humidity. Commonly cited adult enclosures are around 4 by 2 by 4 feet or larger.
Why does my water dragon rub its nose on the glass?
They run at clear barriers they cannot perceive, which causes chronic snout abrasion. Adding screen, plants or an opaque band at eye level is the standard prevention.
