Pet Geckos: A Straight-Talk Care & Buyer’s Guide

“Geckos” sounds simple until you actually start shopping for one. A leopard gecko, a crested gecko, a tokay gecko, and a leachianus are all geckos, but their care, temperament, enclosure style, feeding routine, and overall keeper fit are completely different. That is why a good gecko page cannot pretend there is one universal gecko setup.

This guide covers the main gecko species most commonly kept as pets, what makes each one different, who each one tends to fit best, and what kind of care each one actually needs. It also breaks down the shared rules that matter across the group, like matching the cage to the animal, understanding insectivore versus omnivore diets, using the right temperature and humidity range, and buying from the right source the first time.

Quick Facts (know the group in two minutes)

“Gecko” is a category, not one species. Good gecko care starts with choosing the right kind, not buying one first and figuring it out later.
Main pet gecko groups: Leopard geckos, African fat-tailed geckos, crested geckos, gargoyle geckos, chahoua geckos, leachianus geckos, giant day geckos, tokay geckos, mourning geckos, and Chinese cave geckos.
Body styles vary a lot: Some are ground-dwelling and hide in burrows, some are arboreal and want height, and some are tiny colony geckos that behave nothing like the big display species.
Diets vary too: Some geckos are strict insectivores, while others do best on a gecko diet powder plus insects.
Humidity is not one-size-fits-all: Some geckos want dry air with a humid hide, while others need a tropical setup that cycles between damp nights and drier days.
Adult size range is broad: Pet geckos can stay under 4 inches or grow into thick-bodied, heavy animals well over 10 inches.
Temperament varies from calm to very reactive. Some are excellent beginner reptiles. Others are display animals first and should be treated that way.
Lifespan: Many commonly kept geckos live 10-20+ years with good husbandry.
Experience level: Depends entirely on species. Leopard and crested geckos are common starting points. Tokays, leachies, and delicate tropical species are not.

Species, “Subspecies,” and Why the Label Matters

With geckos, hobbyists usually talk more in terms of species, locality, line, island form, or morph than a single neat list of subspecies. That matters because “gecko care” is too broad to mean much on its own. The difference between a dry terrestrial leopard gecko setup and a tropical arboreal leachie setup is huge. Even within the same general group, labels still matter. A high-end leachianus from a named island form is not the same thing as a random mixed animal, and a common leopard gecko morph is not priced or marketed the same way as a carefully built boutique line.

Bottom line: if a seller uses the word “gecko” like that should be enough information, it usually is not. You need the exact species, and in some cases the morph or locality too.

The Main Pet Gecko Types, and What Each One Is Actually Like

Leopard Gecko (Eublepharis macularius)

Leopard geckos are one of the most common and beginner-friendly reptiles in the hobby for good reason. They are terrestrial, usually easy to feed, generally tolerant of handling, and widely available in both pet stores and breeder circles. They are also one of the most misunderstood because people assume “easy” means “can thrive in a tiny bare box.”

Typical adult size: 7-10 inches
Core care: Basking surface 94-97°F, warm hide 90-92°F, cool zone 70-77°F, ambient humidity about 30-40% with a proper humid hide
Diet: Insects only
Temperament: Usually calm, steady, and one of the easiest geckos to handle
Typical price: Roughly $50-$300 for common animals, with premium morphs and projects going much higher
Pros: Great beginner fit, forgiving compared with many other geckos, easy to observe, widely available, and simple to house well
Cons: Commonly overfed, commonly undersupplemented, often kept too dry or too sterile, and some morph lines can come with quality concerns

African Fat-Tailed Gecko (Hemitheconyx caudicinctus)

African fat-tails are often described as the quieter, shyer cousin of the leopard gecko. That is not a bad way to think of them, but it still undersells the fact that their care is different. They want more humidity, more cover, and generally a less exposed setup than a leopard gecko. They are excellent animals, but they are not just tropical leopard geckos.

Typical adult size: 7-9 inches
Core care: Warm hide about 90-94°F in the active warm season, cool side 72-77°F, nighttime around 72-77°F, with humidity cycling higher than a leopard gecko and a humid hide always available
Diet: Insects only
Temperament: Usually shy, slower, and more secretive than leopard geckos
Typical price: Often around $150-$500 for common animals, with premium lines higher
Pros: Attractive, underrated, often sweet-tempered, and a strong option for keepers who like terrestrial geckos but want something less common than a leopard
Cons: Less forgiving if kept too dry, often spends more time hidden, and can be a little less bulletproof for complete beginners

Crested Gecko (Correlophus ciliatus)

Crested geckos became popular because they are easy to house, do not get huge, and can thrive on a quality crested gecko diet without needing a heavy live-insect schedule. They are one of the best gateway species into arboreal geckos, but they still need thoughtful humidity cycles, decent vertical space, and a keeper who can handle a jumpy lizard without panicking.

Typical adult size: 7-9 inches including tail
Core care: Basking area 82-85°F, cool zone 70-75°F, nighttime 65-72°F, humidity 60-80% with a healthy dry-out period during the day
Diet: Commercial gecko diet plus optional insects
Temperament: Usually mild, but jumpy and not always predictable in hand
Typical price: Roughly $50-$400 for common animals, with high-end trait combinations and boutique lines much higher
Pros: Strong beginner tropical gecko, manageable size, easy feeding compared with strict insectivores, huge variety in pattern and color
Cons: Can drop the tail permanently, can develop floppy tail issues in poor setups, and are often overheated by keepers who assume all tropical reptiles want high heat

Gargoyle Gecko (Rhacodactylus auriculatus)

Gargoyle geckos are often the middle ground between a crested gecko and something a little sturdier. They are still New Caledonian geckos, still do very well on a quality gecko diet, and still want a humid arboreal enclosure, but they usually feel a bit more solid and less spring-loaded than cresties.

Typical adult size: 8-10 inches
Core care: Basking area 82-85°F, cool zone 70-75°F, nighttime 65-72°F, humidity 60-80% with daily cycling
Diet: Commercial gecko diet plus insects
Temperament: Often steadier than crested geckos, though individuals vary
Typical price: Roughly $100-$500 for common animals, with standout blotched, striped, or boutique animals higher
Pros: Hardy, attractive, sturdy build, generally easy to feed, and a very good step for keepers who want an arboreal gecko without going straight into more demanding species
Cons: Still not a high-heat animal, still needs humidity balance, and still should not be treated like a frequently handled pet lizard

Chahoua Gecko (Mniarogekko chahoua)

Chahouas have become one of the most sought-after New Caledonian geckos for keepers who want something more premium than a crested or gargoyle, but not as physically imposing as a leachie. They have a reputation for bold faces, nice heft, and a more serious feel in the hand.

Typical adult size: 8-10 inches
Core care: Basking area 82-85°F, cool zone 72-75°F, nighttime 65-72°F, humidity 60-80%
Diet: Commercial gecko diet plus insects
Temperament: Often confident and food motivated, sometimes a little nippy compared with cresties or gargoyles
Typical price: Often around $500-$1,500+, depending on lineage and look
Pros: Excellent display gecko, premium feel, very attractive pattern and texture, rewarding for keepers who want a step up
Cons: More expensive, less forgiving than a beginner species, and not ideal for someone who wants a cheap or casual first gecko

Leachianus Gecko (Rhacodactylus leachianus)

Leachies are the giants of the gecko world in pet keeping. They are thick-bodied, powerful, vocal, and in many cases much more serious animals than people expect when they first see one. They are fascinating, but they are not “just a bigger crested gecko.”

Typical adult size: Often 10-14+ inches, with some locality forms much heavier-bodied than others
Core care: Basking area 86-88°F, ambient 72-78°F, nighttime 66-72°F, humidity 60-80%
Diet: Commercial gecko diet plus insects, with feeding schedules adjusted by age and locality type
Temperament: Can range from calm to defensive, but even calm leachies are powerful and can bite hard
Typical price: Commonly $400-$2,500+, with premium locality animals and large established breeders going higher
Pros: Massive collector appeal, incredible presence, unique vocal behavior, and one of the most memorable geckos in the hobby
Cons: Expensive, stronger than many new keepers realize, some can be cage-defensive, and they need real space and a keeper who respects what they are

Giant Day Gecko (Phelsuma grandis)

Giant day geckos are among the best daytime display geckos in the hobby. They are bright, active, and visually impressive when housed correctly. They are also one of the worst choices for anyone who measures a reptile’s quality by how easy it is to hold. Their skin is delicate, they are very fast, and they stress easily when handled badly.

Typical adult size: 10-12 inches
Core care: Basking area 85-90°F, cool zone 77-82°F, nighttime 73-77°F, humidity about 40-75%
Diet: Insects plus fruit-nectar style gecko diet or similar support foods
Temperament: Alert, fast, visual, and not built for regular handling
Typical price: Often around $100-$350+, depending on source and quality
Pros: Beautiful daytime activity, strong display value, rewarding planted enclosure species
Cons: Delicate skin, escape-prone, stress easily, and much less practical for handling than many beginners assume

Tokay Gecko (Gekko gecko)

Tokays are one of the most famous geckos in the world, and for many keepers they are one of the most misunderstood. A settled, well-kept tokay is a stunning animal and can become a great display gecko. It is also a species with a strong feeding response, real bite potential, and little interest in being treated like a docile pet.

Typical adult size: 10-14 inches
Core care: Basking area 90-100°F, cool zone 80-85°F, nighttime 76-80°F, humidity 60-80%
Diet: Insects, with occasional vertebrate prey used by some keepers for large adults
Temperament: Bold, often defensive, very food responsive, and best understood as a display gecko
Typical price: Often around $50-$250 for common animals, with selectively bred or unusual forms going higher
Pros: Gorgeous color, strong presence, hardy when well-started, and one of the most iconic geckos in the hobby
Cons: Not a beginner handling gecko, often imported, can be loud, and can make a mess of a keeper who gets careless

Mourning Gecko (Lepidodactylus lugubris)

Mourning geckos are tiny, fascinating, and a completely different kind of pet gecko experience. They are usually kept in groups or colonies, they are famous for reproducing without males, and they are far more about observing a planted micro-world than about handling.

Typical adult size: 3-4 inches
Core care: Basking area 80-85°F, cool zone 70-75°F, nighttime 65-72°F, humidity 60-80%
Diet: Commercial gecko diet, tiny insects, and nectar-like foods
Temperament: Tiny, fast, social by gecko standards, and escape-prone
Typical price: Often $20-$100, frequently sold in pairs or small groups
Pros: Great planted vivarium species, fascinating colony behavior, very little space needed compared with larger geckos
Cons: Extremely easy to lose, not a handling pet, reproduction can happen quickly, and their tiny size means maintenance mistakes show up fast

Chinese Cave Gecko Group (Goniurosaurus spp.)

Chinese cave geckos and related Goniurosaurus species are some of the best-looking nocturnal display geckos in the hobby. They have a calm, almost polished look to them, and many keepers who enjoy leopard geckos but want something more uncommon eventually end up here.

Typical adult size: Usually around 7-9 inches depending on species
Core care: Warm hide or basking area 80-82°F, cool zone 72-77°F, nighttime 68-72°F, humidity roughly 50-90% with natural cycling
Diet: Insects only
Temperament: Usually shy and nocturnal, more of a display gecko than a handling gecko
Typical price: Often around $150-$600+, with some species or lines priced much higher
Pros: Beautiful pattern, cooler-temperature profile, rewarding for keepers who like humid nocturnal geckos
Cons: More sensitive than beginner species, less common, and often not ideal for someone who wants a visible all-day pet

Other Geckos You Will See in the Hobby

The list above covers the main gecko types most hobbyists are actually choosing between, but they are not the only ones. Leaf-tailed geckos, chameleon geckos, house geckos, Uroplatus, and several more specialized species also show up in serious collections. Most of those are better thought of as niche projects, not general entry-level pet geckos.

Morphs, Localities, and Why Fancy Labels Matter More in Some Geckos Than Others

Not every gecko market works the same way.

Leopard geckos: Heavy morph market, huge trait list, lots of line breeding, and a wide range in quality.
Crested geckos: Trait-driven pricing is common, especially for structure, pattern, and newer high-end projects.
Gargoyle geckos: Pattern and color matter, but the market is not as broad as cresties.
Chahoua and leachianus geckos: Locality, island form, lineage, and breeder reputation can matter as much as raw appearance.
Day geckos and tokays: Selective lines exist, but basic husbandry and whether the animal is captive-bred or imported often matter more than a flashy sales description.
Cave geckos: Species identity and source quality often matter more than hype wording.

Takeaway: a fancy label does not always equal a better gecko. In some groups it matters a lot. In others it mostly matters because it raises the price.

Pet Store Geckos vs Boutique-Bred Geckos

This split matters more than a lot of new keepers realize. Some geckos, like leopard and crested geckos, are so widely bred in captivity that you can find decent animals in many places. Others, like tokays, day geckos, and more specialized tropical species, are much more likely to show up as stressed, imported, poorly documented, or loosely represented animals if you shop carelessly.

Pet store animals: Often easier to find, sometimes cheaper, and sometimes perfectly fine. They can also be underfed, mislabeled, badly supplemented, or sold with weak care advice.
Boutique breeder animals: Usually better documented, more consistently established, and more honestly represented. They cost more for a reason.
What you are really paying for: Feeding records, good early growth, better hydration, cleaner lineage, and a breeder who knows what they produced.

If you are buying a gecko where source quality strongly affects outcome, especially tokays, day geckos, cave geckos, chahouas, and leachies, buying the right animal the first time usually saves money and headaches.

Behavior & Temperament Across the Group

One of the biggest mistakes new keepers make is assuming all geckos are handleable little lizards. They are not.

Best handling fit: Leopard geckos, and sometimes African fat-tails
Often manageable but jumpy: Crested geckos and gargoyle geckos
Mostly display geckos: Chahoua geckos, leachianus geckos, giant day geckos, tokay geckos, mourning geckos, and Chinese cave geckos
Species to respect physically: Tokays because of attitude and bite, leachies because of jaw strength and body power, day geckos because of delicate skin, mourning geckos because of size and escape risk

That does not mean display geckos are bad pets. It just means you enjoy them differently. A beautifully planted tokay or day gecko enclosure can be far more rewarding than a species that only matters when it is in your hand.

Diet & Feeding (insectivores are not the same as gecko diet species)

Strict or mostly insectivorous geckos

Leopard geckos
African fat-tailed geckos
Chinese cave geckos
Tokay geckos

These geckos do best on a varied insect diet, with proper calcium and vitamin supplementation. Roaches, crickets, silkworms, black soldier fly larvae, mealworms, and other appropriate feeders can all play a role depending on species and size.

Omnivorous or fruit-diet geckos

Crested geckos
Gargoyle geckos
Chahoua geckos
Leachianus geckos
Mourning geckos
Many day geckos benefit from similar support foods too

These species generally do well on a quality commercial gecko diet, plus insects to varying degrees depending on age and species. One of the most common mistakes is either giving them only powder forever or treating them like they are insect-only geckos when they are not.

Feeding frequency, in simple terms

Babies and juveniles: Usually need more frequent feeding than adults, often daily or every other day depending on species
Adult insectivores: Often do well on 2-4 feedings per week, depending on size, season, and body condition
Adult New Caledonian geckos: Usually thrive on a rotating schedule of gecko diet and insects rather than huge meals all at once

Do not chase size with food. Obesity is common in leopard geckos and not rare in other gecko species either. A healthy gecko should look well-fleshed, not overstuffed.

Temperatures, Humidity, and Lighting (where gecko care really splits apart)

If there is one thing to remember from this whole page, it is this: there is no single gecko temperature or humidity setup.

Dry to semi-arid terrestrial geckos

Leopard gecko: Lower ambient humidity, strong warm hide, humid hide always available
African fat-tail: Warmer hide similar idea, but overall more humidity and more moisture cycling than a leopard

Cooler tropical arboreal geckos

Crested, gargoyle, chahoua, mourning: Mild basking area, cooler nights, higher humidity with daily rise and fall

Warmer tropical arboreal geckos

Leachianus, giant day, tokay: Stronger basking zone, warmer overall ambient range, high humidity, lots of vertical structure

Cool humid nocturnal display geckos

Chinese cave geckos: Gentle warmth, cooler nights, higher humidity, lots of cover

Do geckos need UVB?

This answer depends on species and setup, but in general, many geckos benefit from properly scaled UVB even if they can survive without it when supplementation is perfect. That is especially true when the animal has a natural basking opportunity and the keeper understands how to use low to moderate UVB correctly.

Enclosure & Habitat: Match the cage to the gecko, not the word “gecko”

Terrestrial geckos

Leopard geckos, African fat-tails, and cave geckos need floor space, multiple hides, clutter, and the ability to move between warm and cool areas. They do not need giant empty towers just because they can climb a little.

Arboreal geckos

Crested, gargoyle, chahoua, leachianus, mourning, day, and tokay geckos need height, perches, foliage, and usable upper-level space. A tall enclosure without branches and cover is still a bad enclosure.

Substrate and furnishings

Leopard geckos: Arid or semi-arid naturalistic substrate, dry surface areas, humid hide
African fat-tails: More moisture-retentive naturalistic setup with humid retreat areas
Arboreal tropical species: Moisture-friendly substrate, cork, branches, vines, foliage, and multiple rest options at different heights
Display species: More visual cover almost always helps them settle better

If the cage looks pretty but does not let the gecko thermoregulate, hide, drink, rest, and move naturally, it is still not a good setup.

Shedding, Hydration, and Tail Issues

Geckos tend to show hydration and husbandry mistakes quickly.

Leopard and African fat-tail geckos: Bad sheds usually point to poor hydration access, poor humid hide use, or low-quality overall care
Crested and gargoyle geckos: Humidity balance matters, but so does having a healthy dry-out period instead of a constantly wet box
Day geckos: Rough handling can damage skin fast
Leachies and tokays: Stress and rough cage interactions can lead to injuries that new keepers underestimate
Crested geckos: Tail loss is permanent
Gargoyles and leopards: Tail loss matters, but they are not as famous for it as cresties
Mourning geckos: Tiny body size means even small hydration or nutrition problems can show up quickly

Handling & Safety (what not to do)

Do not overhandle display species. Tokays, day geckos, cave geckos, many leachies, and mourning geckos are best appreciated with minimal contact.
Do not peel geckos off surfaces roughly. This is especially important with day geckos and any species clinging tightly to glass or cork.
Do not underestimate bites. Tokays and leachies can make a real impression if you get careless.
Do not let jumpy arboreal geckos launch blindly. Crested and gargoyle geckos can move faster than people expect.
Do not let children treat geckos like toys. A calm leopard gecko can still be stressed by bad handling, and many gecko species are simply not appropriate for kids to handle at all.

Health Issues That Show Up Most Often

The big ones across geckos are usually husbandry-driven:

Metabolic bone disease: Poor calcium, poor supplementation, poor UVB, or some combination of all three
Dehydration: Bad humidity management, weak access to drinking opportunities, or a cage that dries the animal out constantly
Bad sheds: Common in geckos kept in the wrong humidity profile
Obesity: Especially common in leopard geckos and heavily fed adults in general
Parasites: A major concern in imported or poorly sourced animals
Floppy tail problems: Mostly discussed in crested geckos, but setup design matters for arboreal geckos in general
Mouth and skin injuries: Often tied to stress, poor decor, rough handling, or cage panic
Egg-related strain: Most obvious in species that lay frequently, especially colony species like mourning geckos

Quarantine still matters. Even common geckos should be isolated and watched before they are considered safe additions to a collection.

Daily/Weekly/Monthly Care Plan (simple and repeatable)

Daily

Check posture, breathing, eyes, tail condition, and overall alertness
Confirm warm and cool temperatures
Refresh water and remove obvious waste
For tropical species, make sure humidity is cycling the way you intended

2-4 times per week

Feed according to species and age
Replace uneaten insects or diet mix
Light misting or hydration support for species that need it

Weekly

Clean ledges, hides, glass, and heavily used decor
Check body condition and note behavior changes
Inspect toes, tail, mouth, and shedding areas

Monthly

Weigh the gecko if practical for the species
Review feeding volume and body condition
Replace substrate or do a deeper enclosure clean as needed

Common New-Keeper Mistakes (and quick fixes)

Buying “a gecko” without choosing the species first.
- Fix: Pick the species, then build the setup around that exact animal.
Using the same heat and humidity for all geckos.
- Fix: Learn whether your gecko is dry-terrestrial, humid-terrestrial, mild tropical arboreal, or warm tropical arboreal.
Overheating New Caledonian geckos.
- Fix: Cresteds, gargoyles, and chahouas are not high-heat animals.
Keeping leopard geckos too dry or too sterile.
- Fix: Dry ambient air does not mean no humidity support. They still need a proper humid hide and a real thermal gradient.
Feeding the wrong type of diet.
- Fix: Do not treat insectivores like fruit geckos, and do not treat New Caledonian geckos like strict insectivores.
Handling species that do not want to be handled.
- Fix: Let display geckos be display geckos.
Buying imported animals because they are cheap.
- Fix: In species where source quality matters, pay for the better animal instead of paying later in stress and vet work.
Underestimating how specialized larger tropical geckos can be.
- Fix: Tokays, leachies, day geckos, and more delicate tropical species should be chosen on purpose, not on impulse.

Which Gecko Is Right for You?

Best all-around beginner gecko: Leopard gecko
Best beginner tropical arboreal gecko: Crested gecko
Best sturdier New Caledonian option: Gargoyle gecko
Best shy terrestrial alternative to a leopard gecko: African fat-tailed gecko
Best premium New Caledonian step-up species: Chahoua gecko
Best giant collector gecko: Leachianus gecko
Best daytime visual display gecko: Giant day gecko
Best for keepers who want bold attitude and serious presence: Tokay gecko
Best tiny colony gecko: Mourning gecko
Best cool-humid nocturnal display gecko: Chinese cave gecko

There is no single “best gecko.” There is only the best gecko for the kind of keeper you actually are.

Practical Buying Tips (before you spend the money)

Ask whether the animal is captive-bred, farm-bred, or imported.
Ask for feeding records. Especially with younger geckos and higher-value species.
Check the tail and body condition. The gecko should not look pinched, weak, or dried out.
Look at the toes, jawline, and spine. Poor early care often leaves visible clues.
Ask what the animal is currently eating. That matters a lot with New Caledonian species and tiny geckos.
Ask what label means what. Morph, locality, island form, and line-bred are not interchangeable terms.
Budget for the setup first. A cheap gecko in a bad setup is more expensive than a better gecko housed correctly from day one.

FAQ (fast answers to the questions people always ask)

Which gecko is best for beginners?
Usually a leopard gecko if you want a terrestrial, more handleable pet, or a crested gecko if you want a smaller arboreal species with easy diet options.

Do all geckos need UVB?
Not always as a hard survival requirement, but many do better when it is provided correctly. The species, intensity, and setup matter.

Can geckos live together?
Most should be housed alone. Mourning geckos are a clear exception, and some keepers co-house other species under very specific conditions, but solo housing is the default safe answer.

Which geckos are best for handling?
Leopard geckos are usually the strongest answer. Some African fat-tails also do well. Many other geckos are better as display animals.

Which gecko gets the biggest?
Leachianus geckos are the standout giant in common pet gecko keeping.

Which geckos can live on gecko diet powder?
Crested, gargoyle, chahoua, and leachianus geckos are the main examples, with mourning and day geckos also benefiting from similar support foods depending on the setup and feeding plan.

The Bottom Line

Geckos are not one lane of reptile keeping. They are a huge category that includes some of the easiest beginner reptiles in the hobby, some of the best planted vivarium display animals, and some species that absolutely should not be bought on impulse. Once you stop treating “geckos” as one thing, picking the right one gets much easier.

At Majestic Reptiles, the honest answer is that the right gecko depends on what you actually want. If you want a calm beginner gecko, the answer is different than if you want a high-end New Caledonian project, a bright planted-vivarium display species, or a serious collector gecko with real presence. The goal is not to push every gecko to every keeper. The goal is to match the species to the person correctly from the start.
