Rankin's Dragon
Pogona henrylawsoni
The pocket-sized bearded dragon — the same sunny, hand-tame charm in a lizard half the size.
Difficulty: Beginner–Intermediate Printable care sheet →
Think of a Rankin's dragon as a bearded dragon's pocket-sized cousin — same sunbathing, head-bobbing, arm-waving personality in a body that tops out around a foot long. They're alert, curious, and often bold enough to take food from your hand within weeks. Because they're small and even-tempered, they get sold as "easy," but easy still means a big enclosure, a proper basking hotspot, and strong UVB. Do that and you've got a decade-plus of one of the most engaging little lizards in the hobby.

Care at a glance
| Adult size | 10–12 in (25–30 cm) total length including tail; occasional large females to ~14 in |
|---|---|
| Lifespan | 8–15 years in captivity with good care; most well-kept dragons reach 10–12 years |
| Enclosure | Minimum 36 x 18 x 18 in (roughly a 40-gallon "breeder"-footprint) for a single adult — bigger is better. A 48 x 24 x 24 in front-opening enclosure gives far more room to thermoregulate and forage, and is required footprint if you ever consider a pair. |
| Basking / warm zone | Basking surface 105–113°F (40–45°C) directly under the lamp. Rankin's are a full-time basking species — this is a real, measured hotspot from an overhead halogen/incandescent flood, not a stick-on gauge guess. |
| Cool side | Cool end 77–85°F (25–29°C), giving a true warm-to-cool gradient across the enclosure |
| Night | Night drop is healthy — down to 65–72°F (18–22°C) is ideal, and brief dips to ~55°F (13°C) are tolerated with no supplemental heat. All lights off at night; no colored "night bulbs." |
| UVB & lighting | High UVB — same requirement as a bearded dragon (Ferguson Zone 3–4, target UVI ~3.0–4.5 at the basking spot on a Solarmeter 6.5). Use a linear T5 HO tube (Arcadia Desert 12% / Dragon 14% or Zoo Med ReptiSun T5 HO 10.0) running about 1/2–2/3 the enclosure length, in a reflector. Mount over the basking end: roughly 11–12 in above the basking surface if over mesh, or 16–18 in if inside with no screen. Replace T5 tubes every 12 months. |
| Humidity | Low/arid — 30–40% average is the sweet spot (fluctuations up to ~50% are fine). This is a dry-country species; chronic damp invites respiratory infection. |
| Substrate | Loose, diggable, arid substrate at least 2 in deep — a washed play sand + topsoil mix (~60/40), or a commercial desert-soil blend. Skip pure calci-sand and loose walnut shell. Bare tile or paper towel works for quarantine/hatchlings but a naturalistic dig substrate lets adults burrow and thermoregulate. |
| Diet | Omnivore that shifts with age. Juveniles (roughly 3–12 months) lean insect-heavy — about 60–70% gut-loaded feeder bugs, 30–40% greens, bugs offered 1–2x daily. Adults flip to plant-forward — about 20–30% insects (2–3x/week) and 70–80% leafy greens and veg daily. Staple insects: dubia roaches, crickets, black soldier fly larvae. Staple greens: collard, turnip, mustard greens, dandelion, endive. Always offer fresh water. |
| Supplements | Lightly dust feeder insects with calcium. Simplest modern approach: an all-in-one like Repashy Calcium Plus LoD on every insect feeding (it supplies calcium + low-dose D3 + vitamins). If using plain supplements instead, alternate plain calcium (most feedings) with a reptile multivitamin (about once weekly) — proper UVB does the heavy lifting on D3, so avoid over-dosing D3. |
What it's like to live with a Rankin's Dragon
Best kept solo. They're social to watch, not social to house — cohabiting risks bullying, stress, tail/toe nips, and one animal quietly monopolizing the basking spot while the other declines. If anyone attempts a pair, it demands a much larger enclosure (48 x 24 x 24 in minimum), duplicate basking/UVB zones, and constant weight monitoring; never house two males, and never mix Rankin's with true bearded dragons (P. vitticeps).
Your first month together
The settling-in period, in order — so you know what's normal and when not to worry.
- Build and dial in the enclosure BEFORE the dragon comes home — verify basking surface temp with a digital probe/IR thermometer and UVI with a Solarmeter, don't trust bulb-box claims.
- Give a week or two of low-handling settling time; let it eat and bask reliably first.
- Offer food at the same time daily and log what's eaten — appetite is your #1 health signal.
- Keep it simple at first (paper towel substrate + hides) so you can monitor droppings and spot any parasites; move to dig substrate once settled.
- Find and phone an exotics/reptile vet now, and budget for an initial fecal parasite check.
Through the year, and as they grow
Many healthy adults slow down or brumate in the cooler months — reduced appetite, more hiding, and long sleeps for weeks to a couple of months. It's normal in a dragon that's a good weight and was recently vet-checked; keep water available, don't force-feed, and weigh weekly. Photoperiod naturally shifts too (about 11 hrs light in winter, 13 in summer). A brumating-but-thin or unwell dragon is NOT normal — see a vet before assuming brumation.
The pet store gets these wrong
Common myths, kindly corrected — no shame for having believed them.
- "They're tiny, so a 20-gallon is fine." No — small dragon, big needs: 36 x 18 x 18 in is the floor, and bigger genuinely makes them more active and healthier.
- "Rankin's don't need much UVB because they're small." False — they're a full-sun basking species with the same high-UVB requirement as a full-size bearded dragon.
- "They're a good beginner lizard because they need little." They're beginner-friendly in temperament, not in equipment — the heat/UVB/enclosure bill is the same as a beardie.
- "You can keep two together for company." They don't need companions and usually do worse in pairs; solo is the safe default.
- "A colored night bulb keeps them warm safely." Skip it — they need darkness and a natural night drop, and red/blue night lamps disrupt sleep.
Before you buy
- A 36 x 18 x 18 in (or larger) front-opening enclosure — the biggest single cost, buy it first.
- A proper lighting rig: overhead basking flood on a dimmer/thermostat PLUS a linear T5 HO UVB tube in a reflector — this pair is non-negotiable.
- Measuring tools: a digital probe or IR thermometer for the basking surface, and ideally a Solarmeter for UVI.
- A steady feeder-insect supply (dubia/crickets/BSFL) you can gut-load, plus fresh greens weekly.
- A located exotics vet and a small emergency fund — these dragons live 10+ years.
💷 The rankin's dragon itself is usually the cheapest part — see the real cost of keeping one (upfront + ongoing, no sales pitch).
See a reptile vet if…
We can't diagnose from afar — but these are the signs to stop watching and get a professional:
- Not eating for more than a week or two outside of brumation, or clear weight loss you can feel along the spine/hips.
- Any open-mouth breathing, mucus, wheezing, or puffing at the throat when not basking — possible respiratory infection.
- Weak, jerky, or trembling limbs, a rubbery jaw, or a dragon that can't lift itself to walk — classic signs of metabolic bone disease (UVB/calcium failure).
- Straining, no droppings for an unusually long stretch, or a swollen firm belly — possible impaction, an emergency in a dragon on the wrong substrate/temps.
- Sunken eyes, thick stringy saliva, wrinkled skin, or sustained lethargy — dehydration or systemic illness; see an exotics vet, don't wait it out.

Never
- Never rely on UVB claims from the box — measure UVI or replace T5 tubes on a strict 12-month schedule.
- Never use a heat rock or under-tank heat mat as the main heat source — dragons need overhead radiant heat and can get contact burns.
- Never leave a colored night light on — they need true darkness and a night temperature drop.
- Never feed wild-caught insects or fireflies (fireflies are toxic and can be fatal).
- Never house two males together, and never mix Rankin's with full-size bearded dragons.
Common rankin's dragon questions
How hard are Rankin's Dragons to keep — are they good for beginners?
Beginner–Intermediate. Hardy, calm, and forgiving — genuinely one of the friendlier first lizards. What bumps it above "pure beginner" is the same thing every arid basker needs: real overhead heat, strong UVB with the right mounting distance, and a big enough enclosure. Get the lighting and space right up front and the day-to-day is easy.
What do Rankin's Dragons eat?
Omnivore that shifts with age. Juveniles (roughly 3–12 months) lean insect-heavy — about 60–70% gut-loaded feeder bugs, 30–40% greens, bugs offered 1–2x daily. Adults flip to plant-forward — about 20–30% insects (2–3x/week) and 70–80% leafy greens and veg daily. Staple insects: dubia roaches, crickets, black soldier fly larvae. Staple greens: collard, turnip, mustard greens, dandelion, endive. Always offer fresh water.
