Why Geckos Make Great Pets
Geckos are some of the most approachable reptiles you can keep. They're generally small, relatively easy to care for, and many species tolerate handling well once they're acclimated. But here's what a lot of first-time reptile owners don't realize: the word "gecko" covers over 2,000 species, and the ones commonly kept as pets have wildly different care requirements, temperaments, and lifestyles.
Choosing the right gecko species is arguably more important than any individual husbandry decision you'll make after that. A crested gecko and a tokay gecko are both geckos, but they might as well be different animals when it comes to what they need from you. So let's compare the most popular pet gecko species side by side and help you figure out which one fits your life.
Leopard Gecko
If geckos had a popularity contest, the leopard gecko would win in a landslide. Eublepharis macularius is the most widely kept gecko species in the world, and for good reason.
What They're Like
Leopard geckos are terrestrial — they live on the ground, not climbing walls. They're crepuscular, meaning they're most active at dawn and dusk. They're docile, rarely bite, and tolerate handling well, which makes them fantastic for beginners and kids (with supervision). Adults reach 7 to 10 inches and live 15 to 20 years, with some reaching 25+ years.
Housing Requirements
A 20-gallon long tank is the minimum for one adult, though 40 gallons is increasingly recommended. They need a warm side (88 to 92 degrees Fahrenheit) and a cool side (around 75 degrees). Belly heat from an under-tank heater or overhead heat source is important since they absorb heat from below. UVB isn't strictly required but is increasingly recommended by veterinarians and breeders for overall health. Provide multiple hides — at least one on the warm side, one on the cool side, and one humid hide for shedding.
Diet
Leopard geckos are insectivores. They eat crickets, mealworms, dubia roaches, waxworms (as treats), and other feeder insects. All food should be dusted with calcium powder and occasionally with a multivitamin. They don't eat fruit, vegetables, or commercial gecko diets — it's insects only.
Best For
First-time reptile owners, families with children, anyone who wants a handleable gecko that's easy to care for and has a straightforward diet.
Crested Gecko
The crested gecko (Correlophus ciliatus) is probably the second most popular pet gecko and has been exploding in popularity over the past decade. They were actually thought to be extinct until they were rediscovered in New Caledonia in 1994.
What They're Like
Crested geckos are arboreal — they spend their time climbing on branches, leaves, and the walls of their enclosure. They're nocturnal and relatively calm, though they can be jumpy and fast when startled, especially as juveniles. They don't have eyelids and instead lick their eyes clean with their tongue, which is endlessly entertaining. Adults reach 7 to 9 inches including the tail and live around 15 to 20 years.
One important note: crested geckos can drop their tails, and they don't grow back. Unlike leopard geckos and many other species, a tailless crested gecko stays tailless forever. It doesn't affect their health, and in the wild the majority of adults are actually tailless, but it's something to be aware of during handling.
Housing Requirements
Because they're arboreal, crested geckos need vertical space. A tall 18x18x24-inch enclosure is ideal for one adult. Temperature requirements are one of their biggest selling points — they thrive at room temperature, between 72 and 78 degrees Fahrenheit. In fact, temperatures above 82 degrees can be dangerous for them. No special heating is required in most homes. They do need moderate to high humidity (60 to 80%), achieved through daily misting. UVB is optional but beneficial.
Diet
Here's where crested geckos really shine for convenience. They can be fed primarily on commercial crested gecko diet (CGD) — powdered food that you mix with water to form a paste. Brands like Pangea and Repashy are excellent and nutritionally complete. Supplement with occasional insects like crickets or dubia roaches for enrichment. No gut-loading insects as a primary food source, no juggling different feeder species. Just mix and serve.
Best For
People who want a low-maintenance gecko, anyone who doesn't want to deal with live insects as a primary food source, keepers in cooler climates who don't want to worry about heating.
Gargoyle Gecko
The gargoyle gecko (Rhacodactylus auriculatus) is like a crested gecko's slightly bulkier, slightly feistier cousin. Also from New Caledonia, they share many care similarities with crested geckos.
What They're Like
Gargoyle geckos are semi-arboreal, spending time both climbing and on the ground. They're a bit heavier-bodied than crested geckos and have distinctive bumps on their head that give them their "gargoyle" name. Adults reach 7 to 9 inches and live 15 to 20 years. Their tails can regenerate if dropped, unlike crested geckos. Temperament varies — some are calm and handleable, while others can be nippy, especially as juveniles.
Housing Requirements
Nearly identical to crested geckos. An 18x18x24-inch vertical enclosure, room temperature of 72 to 78 degrees, humidity around 60 to 80% with daily misting. One key difference: gargoyle geckos are more territorial than crested geckos and should generally be housed individually. Cohabitation often leads to tail nipping or worse.
Diet
Same as crested geckos — commercial gecko diet (CGD) as the staple, supplemented with occasional insects. They tend to be enthusiastic eaters and may be more likely to accept insects than some crested geckos.
Best For
Keepers who want something similar to a crested gecko but with a slightly different look and the benefit of tail regeneration. Also good for people who've had crested geckos and want to branch out.
African Fat-Tailed Gecko
Often described as the leopard gecko's calmer cousin, the African fat-tailed gecko (Hemitheconyx caudicinctus) is a terrestrial species from West Africa that deserves more attention than it gets.
What They're Like
African fat-tails are noticeably more docile and slower-moving than leopard geckos. They're less likely to sprint away during handling and tend to be more relaxed overall. Adults reach 7 to 9 inches and live 15 to 25 years. They store fat in their tails (hence the name), and a plump tail is a sign of good health.
Housing Requirements
Similar to leopard geckos — a 20- to 40-gallon terrestrial enclosure with a warm side (88 to 90 degrees), cool side (75 degrees), and belly heat. The main difference is humidity. African fat-tails need higher humidity than leopard geckos — around 50 to 70% with a humid hide always available. They're more prone to shedding issues in dry environments.
Diet
Insectivore, just like leopard geckos. Crickets, roaches, mealworms, and other feeders dusted with calcium and vitamins. No significant dietary differences from leopard geckos.
Best For
People who want something like a leopard gecko but even more laid-back. Great for handlers who prefer a slow, calm gecko that's unlikely to make sudden dashes.
Tokay Gecko
The tokay gecko (Gekko gecko) is the wild card on this list. They're big, they're beautiful, and they will absolutely bite you if given the chance.
What They're Like
Tokay geckos are large — adults reach 10 to 14 inches — and they're known for their stunning blue-gray bodies covered in orange and blue spots. They're also known for being aggressive. Wild-caught tokays are notoriously bitey and defensive, and even captive-bred individuals can be feisty. They have powerful jaws and they're not shy about using them. They're nocturnal and very vocal, producing a loud "to-KAY" call that can be heard across the house.
Housing Requirements
A tall 18x18x24-inch enclosure minimum, though larger is better given their size. Temperatures of 80 to 90 degrees on the warm end, 75 to 80 on the cool end. Humidity of 60 to 80% with daily misting. They need plenty of vertical climbing surfaces and hiding spots.
Diet
Insectivore with a big appetite. They eat larger insects like adult crickets, dubia roaches, and superworms. Occasional pinky mice can be offered to adults. Dust all feeders with calcium and vitamins.
Best For
Experienced keepers who want a display animal and don't mind a gecko that may never enjoy handling. Not recommended for beginners or anyone expecting a friendly, holdable pet.
Day Gecko
Giant day geckos (Phelsuma grandis) are the showstoppers of the gecko world. Electric green bodies with red spots, active during the day, and incredibly fun to watch.
What They're Like
Day geckos are diurnal — active during the day, which means you actually get to see them doing things. They're fast, arboreal, and absolutely not a handling gecko. Their skin is incredibly delicate and can literally tear if grabbed or restrained. They're a look-but-don't-touch species. Adults reach 9 to 11 inches and live 6 to 15 years.
Housing Requirements
Tall vertical enclosure (18x18x24 inches minimum, larger preferred), with lots of bamboo, plants, and climbing surfaces. Temperatures of 80 to 88 degrees basking area with an ambient of 75 to 82 degrees. Humidity of 50 to 70%. UVB lighting is important for this diurnal species.
Diet
Omnivore — a mix of insects and fruit-based gecko diet (CGD). Day geckos enjoy lapping up fruit puree or CGD in addition to hunting insects. This dual diet makes feeding interesting and varied.
Best For
People who want a beautiful, active, daytime display gecko. Keepers who prefer watching their pet rather than holding it. Anyone who wants a vivarium centerpiece.
Quick Comparison Table
Here's a summary to help you compare at a glance. Leopard geckos and African fat-tails are your best bets for handling. Crested and gargoyle geckos offer the easiest feeding and temperature requirements. Tokays and day geckos are best as display animals for experienced keepers. Every species on this list can make a wonderful pet — the key is matching the gecko to your expectations and lifestyle.
