Frilled dragon
Chlamydosaurus kingii · also called Frilled lizard, Frill-necked lizard, Frilled agama
An iconic arboreal agamid famous for the large erectile frill it flares when threatened, often rearing up and running bipedally. A striking, active display animal best suited to keepers who can provide a tall, warm, humid enclosure.

Part of the Agamid Lizards
Old-World agamid lizards including bearded dragons, water dragons, and rock agamas — diurnal, heat- and UVB-dependent baskers, many with vivid display coloration.
Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Habitat & enclosure
Provide a tall, well-ventilated enclosure (minimum ~120 x 60 x 120 cm / 4 x 2 x 4 ft for a single adult; bigger is better) since these are arboreal lizards that climb and bask. Furnish with sturdy diagonal branches, cork bark, and foliage for climbing and security. Maintain a basking surface of 38-43 C (100-110 F) under a tight thermal gradient down to 24-26 C (75-78 F) on the cool side, with a night drop to around 21-24 C (70-75 F). Ambient humidity around 50-70%, raised by daily misting; they drink readily from droplets. Provide a strong UVB source.
Substrate
Use a moisture-retaining bioactive-friendly mix such as topsoil and coir (optionally with sand and leaf litter) that holds humidity without staying waterlogged. Spot-clean daily. Avoid loose calcium sand and dusty substrates that can cause impaction or respiratory irritation.
Equipment & setup
Key equipment: a high-wattage basking lamp on a dimming thermostat, a quality UVB lamp (T5 high-output, replaced on schedule), thermometers and a hygrometer (or digital probes), and a misting system or hand sprayer. A large water dish or dripper helps with hydration. Provide ample vertical climbing decor and a couple of elevated basking spots.
Diet
Primarily insectivorous, taking crickets, dubia roaches, locusts, silkworms, hornworms, and the occasional pink mouse for adults. Gut-load and dust feeders with calcium (with D3 used sparingly when UVB is provided) and a multivitamin. Juveniles eat daily; adults every 1-2 days, adjusting for body condition. Some individuals accept chopped greens and fruit but they are mostly carnivorous.
Behavior & temperament
Diurnal and arboreal, spending most of the day perched and basking. Generally skittish rather than aggressive; the famous frill display (mouth gaping, frill flared, sometimes bipedal running) is a bluff used against perceived threats. With consistent, gentle handling many become tolerant, though they are display animals more than cuddly pets and can be flighty. Keep singly outside of supervised breeding, as males are territorial.
Health
Common issues include metabolic bone disease from inadequate UVB or calcium, dehydration, respiratory infection from cold or stagnant conditions, and stress from inadequate height or hiding. A healthy frilled dragon is alert, full-bodied, and basks readily. Quarantine new animals and have an exotics vet do periodic fecal checks for parasites, which wild-caught imports often carry.
Tips, DIY & hacks
Prioritize enclosure height and basking surface temperature; weak basking is a common cause of poor appetite and lethargy. Mist in the morning and evening to mimic tropical/monsoonal cycles. Seek captive-bred animals where possible to avoid parasite-laden wild imports and to get a calmer, healthier start.
