Crested geckos are one of those species that looks easy on paper and actually kind of is — they don’t need high temperatures, they do well on a commercial diet, and they’re small enough to keep in a modest space. They’re also one of the easiest animals to misjudge when you’re buying from a private seller, because the things that make a crested gecko worth walking away from aren’t always obvious at first glance.
We’ve taken in a lot of crested geckos at Toronto Reptiles — surrendered ones that were thin and stressed, animals that were being kept on pure fruit baby food for years, geckos with floppy tail syndrome that the seller presented as “just how they are.” Most of these animals recovered with proper care. But knowing what to look for before you bring one home saves you from an expensive vet visit, or from taking on a project animal when you wanted a companion.
This guide gives you the complete visual and behavioural checklist for evaluating a crested gecko at point of purchase — whether that’s a Kijiji pickup, a reptile expo, or a breeder’s table. It also gives you the specific questions to ask about feeding history, because for crested geckos, diet history is often the most revealing thing a seller can tell you.
Key Takeaways
- Check the crest and head for fat reserves — a well-nourished crested gecko has visible fat pads above the eyes and a full, rounded head profile; a thin gecko has a bony, angular skull with sunken eye-pads.
- Floppy tail syndrome is permanent — a kinked, wavy, or floppy tail indicates FTS, which is a husbandry-related developmental condition; it doesn’t affect health but is worth knowing before you buy.
- Tail loss is normal, not a red flag — most adult crested geckos in private hands are tailless; they don’t regrow it, but they live completely normally without it.
- Ask specifically about CGD brand and feeding frequency — crested geckos on low-quality or improperly supplemented diets develop nutritional deficiencies over months; the diet history tells you whether you’re inheriting a problem.
- Rescue is a real option — we regularly have crested geckos available at Toronto Reptiles, fully assessed and feeding well on quality CGD.
Before You Go: The Questions to Ask
These questions establish whether the seller actually knows the animal. Ask them before you commit to the trip.
- What are you feeding it, and how often? The answer should name a brand (Pangea, Repashy, Leapin’ Leachie, etc.) with a frequency of every 2–3 days for CGD. Fruit-only diets (baby food, fruit puree) and cricket-only diets without proper supplementation are nutritional red flags. A seller who says “I give it fruit and crickets, it loves it” needs to be asked the follow-up: are you dusting the insects with calcium + D3?
- Does it have a tail? About half the crested geckos you encounter will be tailless — this is normal and does not affect the animal in any meaningful way. It’s just useful to know before you show up expecting a fully tailed gecko.
- Has the tail ever been floppy or kinked? Floppy tail syndrome develops over time in geckos kept without enough climbing structure, or in enclosures that are too barren. A gecko with FTS has it permanently. It doesn’t make the animal unhealthy, but it’s a disclosure item.
- How old is it, and where did you get it? Crested geckos live 15–20 years in captivity. A gecko that’s already 10 years old is a different commitment than a juvenile. Know what you’re taking on.
- What’s the enclosure humidity? Crested geckos need 60–80% relative humidity with lower periods for ventilation. An animal kept at consistently low humidity may have chronic shedding problems.
- Has it ever been seen by a vet, or had any health problems? Most crested geckos kept well never need a vet. But a history of parasites, weight loss, or shedding problems is worth knowing.
The Visual Health Check: What to Look For
Head and Eye-Pad Fat Reserves
This is the most reliable body condition indicator for crested geckos. Look at the top of the head, directly above the eyes. In a well-fed gecko, you should see two small raised pads — fat reserves that sit under the skin. In a healthy, mature animal these are clearly visible, giving the head a slightly widened look above the eye sockets.
In an underweight gecko, these fat pads are diminished or absent, leaving the top of the skull looking flat, angular, or bony. The eye sockets may appear slightly sunken or hollow. This is one of the clearest signs of chronic underfeeding, and it doesn’t fix overnight — a gecko that’s been thin for six months needs weeks to months to rebuild body condition.
Also look at the jaw and facial structure from the front. A healthy crested gecko has a rounded, slightly puffed appearance. Bony jaw angles with little flesh behind them suggest a gecko that hasn’t been eating adequately for some time.
The Tail: FTS, Autotomy, and What to Look For
Crested gecko tails tell three different stories depending on the animal in front of you:
Fully tailed with normal shape: This is what you’d hope for from a well-cared-for juvenile or adult. The tail should hold a gentle natural curve, not droop or curl unnaturally.
Tailless (autotomized): Crested geckos can drop their tails as a stress response, and unlike leopard geckos, they don’t regrow them. A tailless crested gecko is extremely common and lives a full, normal life without it. This is not a health concern. Check that the tail nub is fully healed with no swelling, redness, or wound if the drop was recent.
Floppy tail syndrome: This is worth understanding before you buy. FTS develops when a crested gecko is kept in an enclosure without enough vertical structure to climb — the gecko spends too much time hanging upside down with gravity pulling the tail over the back, and over time the tail’s structural integrity is compromised. The result is a permanently kinked, wavy, or floppy tail that may rest oddly or curl against the body.
FTS is a husbandry indicator — it tells you that the previous enclosure wasn’t set up properly — but it’s not a health emergency. The gecko lives normally. It does tell you that the seller may not have been providing ideal conditions, which is worth factoring into your assessment of their care overall.
Skin, Crest, and Shedding
The iconic eyelashes and crest that give crested geckos their name should be intact and symmetrical. Missing crest “lashes” don’t regrow, so damage there is permanent — again, not a health issue, but a cosmetic note.
Look at the skin overall. Retained shed in crested geckos shows up most often on the toes — check each toe pad carefully. Crested gecko toe pads are their grip surface, and retained shed that constricts a toe over multiple shed cycles will eventually cause the toe to die and fall off. This is common in geckos kept at chronically low humidity. Present-tense retained shed (skin currently stuck) needs to be addressed before sale.
The skin should not show any unusual texture beyond normal scale structure. Open wounds, discolouration, or swelling are abnormal. Tiny moving dots (mites) are less common in crested geckos than in snakes but not unheard of — check the skin folds around the armpits and head.
Eyes
Crested geckos have fixed, lidless eyes — they clean them with their tongue. The eyes should be clear, bright, and responsive. A healthy gecko will track movement. Eyes that are cloudy (outside of a normal shed cycle), sunken, or asymmetrical indicate a problem. Retained shed over the eye is a serious condition that requires veterinary treatment if not addressed promptly.
Movement and Temperament
Ask to handle the gecko. Crested geckos vary widely in temperament — some are handleable and calm, others are chronic jumpers who’d rather be anywhere else. Neither extreme is necessarily unhealthy, but there are some specific things to watch for:
The gecko should move confidently and grip surfaces properly. Crested geckos have setae (microscopic adhesive structures) on their toe pads that allow them to grip smooth surfaces — if the gecko can’t grip the back of your hand or a smooth enclosure wall, the toe pads are compromised, possibly from repeated retained shed or from chronic dehydration. A gecko that moves clumsily or seems disoriented — rather than just jumpy and fast — needs closer examination.
Diet History: The Most Important Question for Crested Geckos
Crested geckos evolved eating nectar and ripe fruit in New Caledonia. In captivity, this translates to a commercial crested gecko diet (CGD) — a powder you mix with water that replicates the full nutritional profile they need, including calcium and vitamin D3. Brands like Pangea and Repashy have been developed in close consultation with veterinarians and are genuinely complete diets.
The problem comes when keepers substitute something cheaper or simpler. Common issues:
- Pure fruit baby food — no calcium, no protein, no D3. A gecko fed this way for months will develop metabolic bone disease (MBD).
- Crickets or dubia only, without dusting — insects alone are not a complete diet for crested geckos and need calcium + D3 supplementation. Some keepers skip this.
- Mixed fruit puree from the grocery store — similar problem to baby food.
- Old or improperly stored CGD — CGD expires and degrades in humidity and heat. A gecko on CGD that’s been sitting open for a year is not getting the nutritional value the packaging promises.
A gecko fed improperly for a long period may not show obvious symptoms until the deficiency is advanced — bone softening, difficulty gripping, lethargy. If the diet history sounds poor, the animal needs a vet assessment before you commit. For guidance on what crested geckos should eat and how to transition an animal onto quality CGD, our complete crested gecko care guide covers the full diet section in detail.

Buying from a Breeder vs. Private Seller vs. Rescue
Crested geckos bred by quality breeders come with full lineage documentation, exact hatch dates, and typically feeding records from day one. If morph is important to you — and the crested gecko morph world is genuinely deep, with Dalmatians, Pinstripes, Lillywhites, Axanthics, and more — a reputable breeder is the way to go. Expect $80–$300+ depending on morph and breeder reputation.
Private sellers are often people who bred a clutch or are rehoming a single pet. The health checks in this guide are specifically designed for this context — use them. Our guide to buying reptiles safely in Ontario walks through how to evaluate a Kijiji or Facebook listing before you commit to the visit.
Rescues provide the most transparency about the animal’s actual condition. A gecko that comes through our doors gets assessed — weight, diet, behaviour, any health issues — before it’s listed for adoption. You know exactly what you’re taking on.
Consider Adopting Instead
Crested geckos are surrendered regularly, often by people who underestimated the 15–20 year commitment, or who picked up a “cool-looking lizard” without realizing it was primarily nocturnal and not a handling animal in the way a bearded dragon is. These are perfectly good animals in need of a second home.
When you adopt through a rescue, the animal has been evaluated, is eating, and any problems have been identified. If you’re open to it, see who’s currently available at Toronto Reptiles — we regularly have crested geckos, and every animal that leaves our care has been assessed before it goes.
Frequently Asked Questions
How much should a crested gecko cost in Ontario?
Standard or “normal” crested geckos from private sellers typically run $40–$80. Morph animals — Dalmatians, Lillywhites, high-contrast Pinstripes — from reputable breeders can run $150–$400+. Be cautious of very cheap animals from sellers who can’t answer basic care questions; these are often animals that have been kept poorly.
Is it okay to buy a tailless crested gecko?
Yes, completely. Tailless crested geckos are extremely common and live normal, healthy lives. The tail loss itself is not a health issue — the only thing to check is that the nub is fully healed if the drop happened recently. Many experienced keepers actively prefer tailless animals because they tend to be older, more settled adults.
What does floppy tail syndrome actually look like?
The tail droops, curls, or waves in a way that doesn’t look structurally normal. When the gecko is resting on a vertical surface, the tail may curl back toward the body rather than hanging naturally. In some cases the tail curves sharply in a kinked pattern. It becomes obvious once you’ve seen a normally-tailed animal for comparison. If you’re not sure, ask the seller to show you what the tail does when the gecko hangs from a branch.
How do I tell if a crested gecko is stressed versus just shy?
Jumping and trying to escape is normal crested gecko behaviour — they’re quick and they prefer to be in control of their movement. Chronic stress shows differently: a gecko that won’t eat, loses weight over weeks, or sits motionless with eyes closed during times it would normally be active (dusk and night) may be stressed beyond normal adjustment. An animal that just arrived in your home will need 1–2 weeks to settle. One that’s been in the seller’s hands for years and is still too stressed to assess is worth being cautious about.
Can I keep crested geckos together?
This is situational. A bonded pair or a female-female pair in a large, well-structured enclosure often works. Two males cohabitating almost never does — they will stress each other out and eventually fight. If the seller has kept multiple geckos together, ask how long and watch for any signs of bite wounds, stress-related weight loss, or dominance behaviour during your visit.
What CGD brand should I use?
Pangea and Repashy are both well-researched, complete diets used by the reptile-keeping community for decades. Pangea has a range of flavours that can be useful for picky eaters. Repashy’s Crested Gecko MRP is the original formula that launched the CGD category. Either is a solid choice. Avoid off-brand products with unverified formulations, especially anything that doesn’t include calcium and D3 in the guaranteed analysis.
How long do crested geckos live?
In captivity with good care, 15–20 years is achievable. Some well-documented animals have exceeded this. This is a long-term commitment that outlasts many relationships, leases, and life plans — the reason they end up in rescues so often. Make sure you’re ready for that before you bring one home. If you want to read more about lifespan factors and what contributes to a long, healthy life, we cover it in the crested gecko lifespan guide.
What if the gecko is being sold with the enclosure?
Buying the gecko and enclosure together from a private seller is often good value, but evaluate the enclosure on its merits. Key things: appropriate height (crested geckos are arboreal — they need height more than floor space), cross-ventilation, humidity retention, adequate climbing and hiding structure. An enclosure that’s missing these things tells you something about how the gecko has been kept. The gecko itself is the priority — the enclosure is replaceable.
The Bottom Line
Crested geckos are genuinely easy animals to keep well — the diet is straightforward, the temperature requirements are forgiving, and they don’t need a huge amount of space. The challenge is inheriting problems from previous care, and the health markers in this guide exist specifically to help you identify those problems before they become yours.
Check the fat pads. Ask about the diet. Look at the toes. And if you’d rather adopt an animal with a known history, we nearly always have crested geckos available through the rescue.
