Golden Gecko (Gekko badenii)

Golden Gecko

Scientific Name: Gekko badenii
Common Name: Golden Gecko, Vietnamese Golden Gecko

Species Overview

Size: Adult Golden Geckos typically reach 6–8 inches (15–20 cm) in total length, including the tail. They are moderately large arboreal geckos with sleek, muscular bodies and broad toe pads adapted for climbing.

Appearance: The Golden Gecko is aptly named for its brilliant colouration. Adults display a smooth, metallic golden-yellow to olive hue across the body, often with faint green undertones and lighter ventral surfaces. Juveniles are usually duller in tone, developing their lustre as they mature. The skin is soft and somewhat delicate, with a velvety sheen that reflects light. Their large lidless eyes range from silver to gold with vertical pupils, and their adhesive toe pads allow them to climb glass, plants, and enclosure walls effortlessly.

Distribution: Native to Vietnam, specifically the Ba Den Mountain region, where they inhabit humid tropical forests and limestone formations.

Habitat: In the wild, Golden Geckos live in tropical forests, preferring high humidity and shaded arboreal environments. They are nocturnal and spend their days concealed in tree hollows, behind bark, or within dense vegetation. In captivity, they thrive in tall, humid enclosures with plenty of climbing structures and cover.

Behaviour: Golden Geckos are nocturnal, alert, and fast-moving. While they are hardy and adaptable, they are best kept as display animals rather than handled pets, as their skin is easily damaged. Males are territorial and should be housed singly or with females only in carefully monitored setups.

Captive Care

Enclosure: Provide a vertically oriented enclosure measuring at least 18 inches × 18 inches × 24 inches (45 × 45 × 60 cm) for a single adult. Include vertical cork bark, bamboo, and sturdy plants (live or artificial) for climbing and concealment. Bioactive or naturalistic setups with live foliage such as pothos or philodendron are ideal for maintaining humidity and stability.

Temperature & Humidity: Maintain daytime temperatures between 78–84°F (25–29°C) with a basking area up to 88°F (31°C). Nighttime temperatures can drop to 70–74°F (21–23°C). Keep humidity between 65–85%, achieved through regular misting, a moist substrate, and live plants. Ensure good ventilation to prevent stagnant air.

Lighting: Provide moderate UVB lighting (5–7%) on a 12-hour day/night cycle. While nocturnal, Golden Geckos benefit from UV exposure to support calcium metabolism and overall health.

Diet: Offer a variety of gut-loaded insects such as crickets, roaches, silkworms, and soldier fly larvae. Adults can also be offered formulated fruit-nectar gecko diets or mashed tropical fruits (e.g., mango, banana) as occasional supplements. Dust all feeders with calcium and multivitamin supplements regularly. Feed juveniles daily and adults every 2–3 days.

Behaviour in Captivity: Golden Geckos are active and striking display animals that become bold with consistent care. They are best appreciated visually rather than handled, as their skin tears easily. With proper husbandry, they are hardy and long-lived, often exceeding 10 years in captivity.

Special Considerations: Avoid handling and provide secure enclosure lids, as this species is quick and capable of powerful leaps. Always regulate heating with a thermostat and maintain consistent humidity levels to prevent shedding issues.

Taxonomy Note

The Golden Gecko (Gekko badenii) belongs to the family Gekkonidae and is part of the Gekko genus, which includes species such as the Tokay Gecko (Gekko gecko). While similar in appearance, G. badenii is smaller, more slender, and less aggressive than its larger relative. It is one of the few Gekko species known for its metallic gold sheen and relatively calm temperament when undisturbed.

Genetics Note

There are currently no recognized morphs of Gekko badenii in the reptile trade. However, subtle natural variation exists in body tone, with some individuals appearing more yellow-gold and others leaning toward olive or greenish hues depending on locality and environment. These differences are naturally occurring rather than selectively bred traits.
