Know whether your Chinese water dragon's care is actually on track.

Your water dragon can't tell you the humidity has dropped or that it's rubbing its snout raw on the glass. baskr watches the pattern across your logs, temperature, humidity, weight and feeding, and shows you what needs attention before it becomes a problem.

Chinese Water Dragon

Humidity low

Averaged 48% vs the 60–80% it needs. Increase misting and check the water area.

Basking spot

32–35°C · 90–95°F

Humidity

60–80%

Adult size

~0.9 m (mostly tail)

Ideal ranges for Physignathus cocincinus, the same targets baskr scores your logs against.

Basking and warm figures are surface temperatures at the spot; cool and ambient are air. Measure with a probe or infrared thermometer at the animal's height.

Chinese Water Dragon: a few things worth knowing

A slice of rainforest: bright green, highly arboreal and semi-aquatic, it dives into water to escape danger.
Most of its ~90 cm length is an elegant, whip-like tail used for balance and swimming.
It doesn't perceive glass, so it repeatedly rubs or dashes its snout against enclosure walls, causing sore, damaged snouts, a signature welfare issue.
It needs both height to climb and a real water area to soak and swim, so the enclosure design matters a lot.
An omnivore that leans insectivore, with more plant matter as it matures.

Where chinese water dragons come from

Rainforests of Southeast Asia

Wild climate. Warm, humid tropical forest along streams in Thailand, Vietnam and southern China; arboreal and semi-aquatic.

Why the care is what it is. This is why baskr targets a 32 to 35°C basking spot, 60 to 80% humidity, a tall planted enclosure with a water area, and visual barriers to protect its snout.

What baskr watches for your chinese water dragon

Logging is the input. The product is spotting when a single off reading becomes a pattern worth acting on.

Basking spot

32–35°C (90–95°F) at a sturdy branch

A cool basking spot undercuts digestion and activity.

Humidity

60–80% with misting or a fogger and a water area

Chronic dryness causes poor sheds, dehydration and respiratory stress in a rainforest species.

Snout condition

A clean, intact snout, no rubbing at the glass

Rostral rubbing leaves the snout raw and infection-prone, add visual barriers and dense planting.

UVB coverage

A good UVB gradient under the foliage, renewed yearly

Weak UVB risks metabolic bone disease in an active, growing basker.

Diet & balance

Insect-led with greens and some fruit, calcium-dusted

An all-insect diet without calcium and plants unbalances a growing dragon.

Weight & condition

Steady and smooth

A downward trend or a thin tail base is an early red flag.

How to set up a chinese water dragon terrarium

Minimum size
Tall and planted: a 120×60×120 cm (4×2×4 ft) enclosure as an adult minimum, taller and bigger is better. Height, climbing branches and a water area matter more than floor space.
Temperatures
Basking 32–35°C (90–95°F), warm ambient days, a cooler shaded zone, a night drop, and 60–80% humidity. Warm, humid and green.
Substrate
A moisture-holding, planted bioactive soil mix (coir/topsoil) that helps hold humidity; heavy planting is part of the design.
Hides & décor
Dense foliage and branches for cover and sight breaks, plus a large water area to soak and swim; the planting also reduces snout-rubbing.
Layout
A tall, densely planted rainforest enclosure: sturdy climbing branches to a basking spot under UVB, high humidity via misting or fog, a large water area, and visual barriers on the glass so it doesn't rub its snout.

Plants for a chinese water dragon terrarium

Safe to include

  • Pothos
  • Ficus
  • Bromeliads
  • Dracaena
  • Hibiscus
  • Sturdy climbing branches and vines

Avoid

  • Pesticide-treated plants
  • Sharp or spiny species
  • Toxic ornamentals

Dense, sturdy planting gives cover, holds humidity, and, crucially, breaks up the glass so the dragon is less likely to injure its snout.

What to feed a chinese water dragon, and what to avoid

Staples

  • Insects: crickets, dubia, locusts, gut-loaded and calcium-dusted

Occasional / treats

  • Leafy greens and some vegetables (more with age)
  • A little fruit
  • The odd appropriately-sized whole prey for adults

Never feed

  • An all-insect diet with no calcium or plants
  • Oversized prey
  • Wild-caught insects

Supplements. Dust insects with calcium (with D3 if UVB is marginal) and a multivitamin about weekly.

Good to know. An omnivore that leans insectivore when young, adding greens and some fruit as it matures. Keep calcium and UVB up for healthy bones.

The gear that matters for a chinese water dragon

The right kind of kit, pick brands you trust.

UVB lighting

A 6–10% T5 HO tube (Ferguson zone 2–3) under the foliage over the basking branch, replaced every 12 months.

Basking heat

A basking lamp to reach 32–35°C at a sturdy branch, on a thermostat.

Thermostat

Controls the heat so a planted enclosure can't overheat.

Misting or fogging

Automatic misting or a fogger to hold 60–80% humidity, with airflow so it isn't stagnant.

Large water area

A big, clean water area to soak and swim, changed regularly.

Visual barriers

Plants or a backing on the glass so the dragon doesn't rub its snout raw on invisible walls.

The kind of thing baskr will tell you

Grounded in your own logs and the ideal ranges above, plain language, never a diagnosis.

Humidity has averaged 48% this week, low for a water dragon (target 60–80%). Increase misting and check the water area, dryness brings bad sheds and respiratory stress.

Snout-rubbing behaviour logged at the glass. Add dense planting and visual barriers before the snout gets raw and infected.

Diet has been all insects lately. Add calcium-dusting and some greens for a growing, active dragon.

Chinese Water Dragon care questions

Why is my water dragon rubbing its nose on the glass?+

Water dragons don't see glass, so they try to move through it and rub or bash their snouts, leaving them raw and infection-prone. Break up the glass with dense planting and visual barriers, give plenty of height and cover, and make sure the enclosure is big enough.

Do Chinese water dragons need water?+

Yes. They're semi-aquatic and use a large water area to soak, swim and escape stress. Combine that with high humidity (60–80%) via misting or a fogger, they're a rainforest species.

What do Chinese water dragons eat?+

They're omnivores that lean insectivore: mostly gut-loaded insects when young, adding greens and some fruit with age. Keep calcium and UVB up to protect their bones.

How big do Chinese water dragons get?+

Around 90 cm (3 ft) total, though most of that is tail. They need a tall, planted enclosure with height, branches and a water area rather than just floor space.
