The Chinese cave gecko is a small, banded, red eyed lizard. It lives in limestone caves and rocky forest on Hainan Island in southern China. It belongs to the eyelid gecko family, Eublepharidae, the same family as the leopard gecko.

Like other eyelid geckos it has moveable eyelids and lacks sticky toe pads. Keepers often call it by its full trade name, the Hainan cave gecko. It is also sold simply as a Chinese cave gecko, one of the more accessible members of the genus Goniurosaurus within the wider world of geckos kept as pets.

Its scientific name is Goniurosaurus hainanensis. It was described in 1908, spent decades lumped in with a mainland relative, and is treated as a valid species today.

A 2025 genetic study even found two deeply split lineages on the island. It is not a common pet store animal, more a niche reptile kept by hobbyists who already know humid, secretive gecko species.

Chinese Cave Gecko Care Overview

Caring for a Chinese cave gecko means recreating a cool, damp cave floor. Not a hot desert tank. That single idea drives the enclosure, the temperatures, the humidity and the feeding schedule.

This species is nocturnal. It spends daylight hours tucked into a hide and becomes active at night. Keepers who expect a basking, sun loving lizard will be disappointed.

Anyone still weighing options should look at our guide to choosing a pet lizard before committing. Keepers who want a shy, long lived, low maintenance nighttime animal tend to find this species rewarding.

It comes from a narrow range on Hainan Island. The Reptile Database notes ongoing concern about wild collection for the pet trade. Buying only captive bred stock matters more here than with most common gecko species.

Enclosure Setup

A single adult does well in a 20 gallon long tank, roughly 30 by 12 by 12 inches. A pair or trio benefits from more floor space, closer to 30 or even 40 gallons. Floor space matters more than height, since this is mainly a ground dwelling species that climbs only a little.

Juveniles can start smaller, in an 18 by 18 by 18 inch enclosure or a well ventilated tub. Move them up as they grow.

Good substrate choices include a mix of organic, fertilizer free topsoil with coco fiber and a little sand. Plain coco fiber, eco earth or orchid bark also work well, as covered in our Hainan cave gecko enclosure guide.

Some keepers raising juveniles prefer paper towel over a humidity chamber so they can watch food intake and droppings closely. Avoid substrates that contain perlite.

Furnish the tank with several hides, since this gecko needs to feel completely enclosed to relax. Add cork bark pieces, flat stones or a background for cover, plus a shallow water dish. Our broader guide to lizard enclosures and reptile supplies covers general setup gear that applies here too.

Heating and Lighting

The Chinese cave gecko does not need intense heat or UVB the way a desert lizard does. Sources differ on the exact numbers to use.

Most care guides put the ambient range in the upper 60s to upper 70s Fahrenheit. Some allow an optional, slightly warmer spot in the high 70s to low 80s Fahrenheit rather than a true basking zone. Nighttime drops into the mid to upper 60s Fahrenheit are considered normal, even beneficial.

One often cited source simply recommends average room temperature with no added heat at all. It warns that excess warmth is more likely to harm this species than help it. Because of that spread, treat any single number as a guideline and watch your own gecko’s behavior.

UVB is not required since the species is nocturnal and does not bask. A very low level UVB tube, such as the Arcadia ShadeDweller ProT5 Kit 7%, is considered optional and harmless by some keepers for general health. Ordinary room lighting on a natural day and night cycle is enough.

What Chinese Cave Geckos Eat

Chinese cave geckos are strict insectivores. Dubia roaches are a staple for most keepers. Crickets, black soldier fly larvae, small superworms, mealworms and hornworms round out the menu.

Waxworms are fine as an occasional treat. They are high in fat, and overfeeding them is a common cause of overweight geckos.

Feed juveniles daily. Feed adults somewhere between two and five times a week, since guides differ on exact frequency. Many keepers feed more often through the warmer breeding months and taper off in winter.

Gut load feeder insects before offering them. Dust prey with a calcium supplement at most feedings, plus a multivitamin powder about once a week. If you provide any UVB lighting, switch to a calcium without added vitamin D3, such as the Zoo Med Repti Calcium without D3.

See our guide on what lizards eat for more on gut loading and supplement schedules across species.

Health and Common Problems

Retained shed and respiratory trouble are the two most common problems. Both usually trace back to humidity that is too low or an enclosure with poor ventilation.

New Chinese cave geckos, especially those with unclear breeding history, commonly carry internal parasites such as coccidia. A quarantine period and a fecal exam from a reptile veterinarian are worth doing before introducing a new gecko to an established collection.

Watch body condition closely. A gecko that looks pinched at the tail base is underweight. One that looks rounded and heavy, especially after a diet heavy in waxworms, is at risk of obesity.

Any lizard that stops eating, loses noticeable weight or breathes with visible effort needs a reptile veterinarian. So does one with stuck shed around the eyes or toes. Our lizard health guide covers warning signs shared across pet lizard species.

Behavior and Temperament

This is a secretive, nocturnal animal. It spends the day hidden and becomes active after lights out.

Reported temperament varies by keeper. Some describe the species as shy and flighty. Others report their individual geckos as curious, willing to stalk live prey once settled in.

Handling is generally discouraged. Like other eyelid geckos, a Chinese cave gecko can drop its tail readily if it feels threatened or grabbed, and the tail never regrows to match the original.

Most keepers treat this as a look, don’t touch species. It is best enjoyed by watching it move around its enclosure after dark.

Breeding

Adults can be sexed by examining the base of the tail from underneath. Males show a visible bulge from their hemipenal structures. Females are smoother in that area.

Males are territorial toward other males and should be housed alone or with females only. One male can typically live with more than one female outside of occasional aggressive encounters.

Breeding activity concentrates in spring and summer. A female typically lays two eggs per clutch and can produce up to four clutches across a season if well fed and in good condition.

Eggs incubated at room temperature in a ventilated container with moist substrate hatch in roughly 60 to 70 days. Hatchlings do well housed alone or in pairs on paper towel with a humid hide, fed daily on pinhead crickets, flightless fruit flies or bean beetles. Most reach young adult size around two years of age.

Lifespan and Size

An adult Chinese cave gecko reaches roughly 8 inches in total length. That modest size fits comfortably in a 20 to 30 gallon enclosure for life.

With consistent care, keepers commonly report a lifespan of 10 to 12 years. That puts it in line with many other small, well kept gecko species.

Precise snout to vent length figures are not published in the available taxonomic record. Total length remains the most reliable number to plan around.

Cost of Keeping a Chinese Cave Gecko

Exact purchase prices are not consistently published by care resources. This species is uncommon enough in the trade that prices vary by breeder and availability rather than following a fixed range.

As a general rule, expect to pay more than you would for a common leopard or crested gecko. Captive bred Goniurosaurus are produced in smaller numbers.

Ongoing costs matter more than the purchase price. Budget for a properly sized enclosure, a thermometer and hygrometer, such as the Zoo Med Digital Combo Thermometer & Humidity Gauge, hides and cork bark, and a steady supply of feeder insects and supplements. Add an occasional veterinary visit for the quarantine check recommended on any new gecko.

Because wild collection pressure has been noted for this genus, buying only from breeders who confirm captive bred lineage is worth the extra cost. Keepers weighing this species against the more common crested gecko or the vocal tokay gecko will find the Chinese cave gecko costs more and is harder to find than either.

Frequently Asked Questions

Is the Chinese cave gecko good for beginners?

It suits keepers who already have experience with humid, secretive gecko species. The care itself is not difficult. The husbandry differs enough from popular starter geckos that a first time owner can easily get temperature and humidity wrong.

Do Chinese cave geckos like to be held?

No. Most keepers and care guides recommend minimal to no handling, since the species stresses easily and can drop its tail if grabbed. It is best kept as an animal to observe rather than handle.

What is the difference between a Chinese cave gecko and a leopard gecko?

Both belong to the eyelid gecko family. The Chinese cave gecko needs cooler temperatures, higher humidity and more hiding cover than a leopard gecko, which comes from a dry, rocky habitat. It is also far less tolerant of handling.

How big does a Chinese cave gecko get?

Adults reach roughly 8 inches in total length. That modest size stays comfortable in a 20 to 30 gallon long enclosure for its entire life.

What does a Chinese cave gecko eat?

It eats gut loaded insects such as dubia roaches, crickets, black soldier fly larvae and occasional hornworms or superworms. Dust prey with calcium and offer a periodic multivitamin. Waxworms are fine only as an occasional treat because of their fat content.

Are Chinese cave geckos endangered?

The Reptile Database notes documented conservation concern for this species, including pressure from collection for the pet trade. The database has even withheld its detailed description from public view for that reason. Buying only captive bred individuals helps reduce demand for wild caught animals.
