Goniurosaurus hainanensis is a unique species that requires attention to its specific needs to thrive. They are native to the tropical forests of Hainan Island in China.
Goniurosaurus hainanensis is a relatively small species, typically growing up to 12 centimeters in length.
To keep them healthy, it's essential to maintain a proper humidity level of 50-60% in their enclosure. This can be achieved by misting the terrarium daily or using a humidifier.
A temperature range of 22-28°C (72-82°F) is also crucial for their well-being, with a slight drop in temperature at night.

Gecko Care
Hainan cave geckos are an interesting alternative species that make rewarding pets. They are small and unique, with black bodies and yellow bands.
They can be a little skittish, but will usually tolerate handling. If you're new to gecko ownership, this species is a great choice.
To create a suitable environment, provide a large enough enclosure for them to explore during their nighttime waking hours. They require relatively cool temperatures, so wood, PVC, or glass enclosures are all suitable.
Here's a temperature guide for your Hainan cave gecko:
- Warm end: 26°C (79°F)
- Cool end: 20-22°C (68-71°F)
In extremely warm homes or during the summer months, consider using a thermostat to regulate the temperature. This will ensure your gecko stays comfortable.
Do Geckos Need Heat?
In most cases, geckos need a warm environment to thrive, but the specific temperature requirements vary depending on the species.
Hainan cave geckos, for example, require a warm end or basking temperature of 26°C (79°F) and a cool end temperature of 20-22°C (68-71°F).
You can achieve the basking temperature using an overhead heating system like a basking lamp or ceramic heater, set to 26°C/79°F on the thermostat.
A thermostat is a must-have to monitor temperatures and switch off the heating equipment if it's not needed, while keeping it on to maintain the set temperature if required.
Some homes may be warm enough for geckos to live without an additional heat source, especially during the summer months.
However, it's always better to have a backup heating system in place, just in case.

Do Geckos Need UV?
Geckos need UV light to metabolise vitamin D3 and utilise calcium from their diet.
Hainan cave geckos, for example, can benefit from sunlight exposure despite their nocturnal habits.

They can be kept with a UVI between 1-2, which can be achieved using specific lighting kits.
An Arcadia ShadeDweller ProT5 Kit placed 25-40cm above the basking area can provide the right amount of UV.
Alternatively, an Arcadia ProT5 Kit - Forest 6% can be used if the distance is between 40-45cm.
The right lighting can make a big difference in a gecko's health and well-being.
Gecko Housing
A Hainan cave gecko's enclosure is a crucial part of its care, and it's essential to get it right. A minimum enclosure size of 90 x 60 x 60cm (3 x 2 x 2ft) is recommended.
For a Hainan cave gecko, a wooden vivarium is a great option, and the Exo Terra Glass Terrarium 90x45x45cm is also a good choice.
To replicate their natural habitat, lots of cover in the form of rocks, logs, cork bark, and hiding caves should be provided. A soil mix like coco soil is recommended to help keep the humidity at a suitable level.

Gecko Enclosure Size
When choosing an enclosure for your Hainan cave gecko, size matters. A minimum enclosure size of 90 x 60 x 60cm (3 x 2 x 2ft) is recommended for these geckos.
You can consider a wooden vivarium as a great option for your Hainan cave gecko. Alternatively, the Exo Terra Glass Terrarium 90x45x45cm is also a suitable choice.
If you're planning to get a Hainan cave gecko, make sure to have a spacious enclosure ready for it.

Decorating a Vivarium
Decorating a vivarium is all about creating a natural environment that your gecko will love.
A soil mix like coco soil is a great option for the substrate, as it helps keep the humidity at a suitable level.
Hainan cave geckos are often found in rock crevices and caves, so their captive environments should replicate this as closely as possible.
To do this, provide lots of cover in the form of rocks, logs, cork bark, and hiding caves.
Foliage like real or artificial plants can provide cover and enrichment for your gecko.
You can choose a more textured and less dense planting substrate like ProRep Bio Life Forest or Arcadia EarthMix if you want to add live plants.
A well-designed vivarium should have a mix of open spaces and hiding places to keep your gecko happy and secure.
Remember, the key is to create a natural environment that mimics the gecko's natural habitat.
Geckos' Diet
Hainan cave geckos are insectivorous, so they need a diet rich in insects. A varied diet of live foods such as crickets, locusts, and cockroaches is essential.
To ensure your gecko gets all the required nutrients, you'll need to supplement their food regularly. We recommend a calcium-rich multivitamin on every feed.
A calcium plus magnesium supplement should be given on every fourth feed. This will help maintain your gecko's strong bones and overall health.
Finally, a vitamin D3 supplement should be given on every eighth feed. This will help regulate your gecko's calcium levels and overall well-being.

How to Buy a Gecko
If you're interested in buying a Hainan cave gecko, you'll need to visit a reputable breeder in person. They don't ship livestock, so it's best to meet them in person.
When selecting a breeder, bring photos of your home and any potential enclosure space to ensure it meets the gecko's housing needs. A 90 x 60 x 60cm (3 x 2 x 2ft) enclosure is ideal.
To ensure you're prepared to provide a suitable environment, be aware of the gecko's specific temperature and humidity requirements. They thrive in temperatures between 26°C (78°F) and 20°C (68°F), with humidity levels between 60-70%.
Before making a purchase, consider the gecko's average lifespan of 10-15 years and its skittish personality. This means they may not be the best choice for inexperienced pet owners.
If you're still interested in buying a Hainan cave gecko, here are some key facts to keep in mind:
Remember, buying a pet is a big responsibility, and it's essential to ensure you're prepared to provide the necessary care and attention.
Sexing & Breeding
Sexing Goniurosaurus hainanensis is relatively easy and can be done by 6-9 months of age.
Males can be visually sexed via pre-anal bulges and pores that align at the base of the tail, while females lack these characteristics.
Breeding Goniurosaurus hainanensis is a straightforward process, especially since they are seasonal breeders.
In areas with distinct seasons, breeders can be kept in groups year-round without adjusting the thermostat, and ovulations can be seen as early as winter.
A brief cooling period of around 5 degrees and off-feeding for a month can stimulate ovulations in more temperate areas.
Females will become visibly gravid by the end of week two, with developing eggs visible from the underside, and will stop eating until the clutch is laid.
Eggs are typically buried in the substrate in a humid area of the enclosure, away from the direct heat source.
It's essential to remove eggs within a day or two of deposition and incubate them between 75-78 degrees Fahrenheit for 60-90 days.
Longer incubation times, typically past 85 days, tend to yield more females, but sex dependency on temperature is not consistent in my experience.
