Caring for Your Pet Water Dragon in Nashua, NH

Water dragons are native to Southeast Asia and the Indo-Australian archipelago. They are accustomed to warm temperatures, high humidity, and environments that allow swimming, climbing, and basking. Water dragons are active, intelligent lizards that require significant space and environmental complexity to thrive.

In captivity, water dragons have been known to live 10–20 years when provided with appropriate husbandry and veterinary care.

Housing

A proper enclosure ensures your water dragon's safety while providing a clean, comfortable, and spacious environment.

Enclosure Size

Water dragons can grow up to 3 feet in length, including the tail. As a general rule, the enclosure should be at least twice the dragon's total length from nose to tail tip.

Asian water dragons are arboreal lizards, meaning they climb and prefer elevated spaces. Because of this, enclosure height is just as important as width. For example:

  • A 3-foot water dragon requires at least a 6-foot-wide enclosure
  • Enclosure depth should be at least half the dragon's length
  • Ideal enclosure height: 4–6 feet

An ideal enclosure for a full-grown adult is approximately 7 feet wide x 3 feet deep x 5 feet high.

Cohabitation

Water dragons may be housed together, but close monitoring is required. Males often tolerate other males better than females, but dominance behaviors can occur. Watch carefully to ensure one dragon is not guarding food, basking areas, or access to water.

Enrichment

Provide ample enrichment, including:

  • Branches, logs, and climbing structures
  • Rocks and basking platforms
  • Hiding areas
  • Plants (real or artificial)

Live plants that are safe and enriching include:

  • Dracaena
  • Hibiscus
  • Ficus bushes
  • Pothos
  • Philodendron
  • Spider plants

Rearrange furnishings periodically to prevent boredom. Clean all props regularly.

Do not use heat rocks, as they can malfunction and cause severe burns.

Water Area

Water dragons require access to a large pool of water covering at least half of the enclosure floor space. The water should be deep enough for the dragon to submerge and swim comfortably.

  • Place branches over the pool to allow diving
  • Change water frequently to maintain cleanliness
  • If creating a naturalistic vivarium with a permanent pool, use an aquarium filter

Substrate

The remaining half of the enclosure should be a ground area.

Acceptable substrates include:

  • Indoor/outdoor carpeting
  • Artificial turf-style reptile carpet
  • Shredded paper
  • Alfalfa pellets

Avoid:

  • Sand
  • Corn cob
  • Wood shavings
  • Bark mulch

These materials can cause impaction, which may require surgical treatment.

Remove uneaten food, fecal matter, and urates daily. Clean and disinfect the enclosure at least once weekly using mild soap followed by a reptile-safe disinfectant or a dilute bleach solution (1 capful bleach per gallon of water). Rinse and dry thoroughly before returning your dragon.

Enrichment

Water dragons do not understand glass and may rub their snouts against enclosure walls, potentially causing permanent damage to the nose and lower jaw.

To reduce this risk:

  • Use a large enclosure
  • Place a visual barrier around the lower outside portion of the enclosure

Lighting

Water dragons require UVA and UVB lighting year-round.

  • Adults: 5.0 UVB
  • Hatchlings and juveniles: 10.0 UVB

Higher UVB output supports rapid growth in younger dragons.

  • UVB lights should be on 12 hours daily
  • Replace UVB bulbs every 6 months, even if visible light is still produced
  • Fluorescent UV bulbs do not provide heat and must be paired with a heat source

Ensure all lights are positioned so the dragon cannot touch or climb onto them.

Natural sunlight can be beneficial when safe and supervised, but glass filters UV rays, so it cannot replace UVB bulbs.

Temperature

Daytime temperatures:

  • Warm side: mid–high 80s°F
  • Basking area: mid-90s°F
  • Cool side: mid-70s°F

Nighttime temperatures: 70s°F, mimicking natural conditions.

Feeding

Water dragons are primarily carnivorous, though they also consume plant matter.

Insects and Protein Options

Insects should be no larger than the distance between the dragon's eyes. Appropriate prey includes:
Crickets (gut-loaded)
Dubia roaches
Earthworms
Locusts
Silkworms
Hornworms (occasionally)
Mealworms and waxworms (limited)
Whole prey items such as pinkie mice, fuzzies, and feeder fish should be offered 2–3 times weekly for juveniles and adults and are valuable sources of calcium and nutrients.
Dust insects with calcium without phosphorus and without vitamin D3 before feeding.

Plant Matter

Offer finely chopped leafy greens daily, including:
Romaine lettuce
Spring mix
Red or green leaf lettuce
Dandelion greens
Mustard greens
Collard greens

Vegetables (smaller amounts):
Squash, carrots, Brussels sprouts
Sweet potato, cauliflower, broccoli
Green, yellow, or wax beans, radish, bell peppers
Fruit should be offered sparingly as treats, such as apples, bananas, berries, grapes, or melon.

Supplements

Calcium without phosphorus or vitamin D3: every meal
Multivitamin with vitamin D3 and vitamin A: once weekly

Feeding Schedule

Hatchlings and juveniles: feed every 1–2 days

Adults: feed every 3–4 days

Taking Your Water Dragon Outdoors

Outdoor exposure can be beneficial when done safely:

  • Only when temperatures are 70–90°F
  • Provide access to shade
  • Use a harness and leash
  • Supervise at all times
  • Protect from predators

Common Medical Problems

Most health issues in water dragons stem from:

  • Improper enclosure hygiene
  • Poor diet or supplementation
  • Inadequate heat
  • Lack of UVB exposure

Learn what is normal for your dragon, including appetite, behavior, and waste production. If changes persist beyond 1–2 days, seek veterinary care.

Emergency signs

  • Bloody stool or urates
  • Heavy breathing or panting
  • Seizures
  • Bloody discharge
  • Lameness
  • Facial trauma

Preventative Care

Juveniles: twice-yearly exams
Adults: annual exams
