🦎 Water Dragons — Guide & Varieties

IN PRODUCTION   Reptiles & amphibians · 2 varieties mapped

A dragon that swims — impressive, semi-aquatic, and needing serious vertical and water space.

Water dragons (Physignathus / Intellagama) are large Asian lizards, 2–3 ft (60–90 cm) including tail, living 10–15 years. They are semi-aquatic: they climb and dive into water to escape. The Chinese water dragon is the common pet. They are personable and tolerant of handling when raised well, but need a big, humid, planted enclosure with a pool.

Not a beginner lizard — the enclosure alone (tall, with a substantial water section) is a project. But a well-kept water dragon is a striking, interactive companion.

How long do water dragons live

Water dragons live 10–15 years. They are robust but need correct humidity and a clean water section; the risks are respiratory infection from dry cool air, tail rot from injury, and stress in too-small cages. A large, humid, enriched setup spans the full lifespan.

Enclosure: tall with a pool

Adults need a 6 ft (180 cm) tall, 4 ft (120 cm) wide enclosure with sturdy branches and a large water pool they can fully submerge in and climb out of. Substrate that holds humidity (cypress, soil). Strong screen top and secure lid — they are climbers and escapees. Provide UVB and a basking branch.

Heat, humidity, light

Basking 95–100°F (35–38°C), ambient 80–88°F (27–31°C), humidity 70–80% via misting and the pool. Strong UVB (10–12%). They are tropical and need consistent warmth and moisture; a dry cage invites respiratory disease. A daylight cycle supports their diurnal activity.

Diet: insect-veg mix

Feed insects (crickets, roaches, occasional pinkie) dusted with calcium, plus chopped greens, fruit, and flowers. Adults eat daily or every other day; juveniles daily. Provide the water pool for drinking and soaking. Overfeeding causes obesity. They can be tamed but may whip with the tail or bite if frightened.
