Tokay Gecko (3rd Generation Captive Bred)

Scientific Name: Gekko gecko
Common Name: Tokay Gecko (3rd Generation Captive Bred)

Species Overview

Size: Adults typically reach 10 to 14 inches (25 to 36 cm) in total length. Males tend to be larger and heavier-bodied.

Appearance: Third-generation captive-bred Tokay Geckos display the classic wild-type appearance unless selectively bred for colour. Their body typically shows blue-grey to slate tones with orange or rust-coloured spotting. Because they come from multi-generational captive lines, some individuals may show slightly cleaner patterning or stronger contrast depending on their lineage, but no morph traits are implied by captive generation alone. Their eyes remain gold to copper, and their body retains the robust musculature and coarse granular skin typical of Tokay Geckos.

Distribution: The species originates from Southeast Asia.
The “3rd Generation Captive Bred” designation means these geckos are F3, descending from at least two prior generations of captive-bred parents.

Habitat: In the wild, Tokays inhabit humid forests, rocky terrain, and human structures. In captivity, they thrive in tall enclosures with abundant vertical climbing space and secure hiding areas.

Behaviour: Tokay Geckos are nocturnal, territorial, vocal, and bold. Captive-bred individuals — especially F3 and beyond — may acclimate more readily and exhibit slightly reduced defensiveness compared to wild-caught Tokays. However, the species’ strong territorial instincts remain consistent. Handling should be limited.

Captive Care

Enclosure: A vertically oriented enclosure measuring 24 inches × 18 inches × 24 inches (60 × 45 × 60 cm) is recommended. Provide cork tubes, dense foliage, branches, and vines to support climbing and security. A soil-based or bioactive substrate helps maintain humidity.

Temperature & Humidity: Maintain daytime temperatures of 80 to 88°F (27 to 31°C) with a basking area near 90°F (32°C). Night temperatures may drop to 72 to 75°F (22 to 24°C). Humidity should remain between 60 and 80%, sustained through regular misting and proper ventilation.

Lighting: Provide moderate to high UVB (5 to 7%) for 12 hours daily. Tokay Geckos benefit physically from UV exposure despite being nocturnal.

Diet: Offer crickets, roaches, silkworms, hornworms, mealworms, and moths. Large adults may occasionally accept a pinkie mouse. Juveniles should be fed daily; adults every 2–3 days. All prey must be gut-loaded and dusted with calcium and multivitamins. Fresh water should be provided daily.

Behaviour in Captivity: Tokay Geckos are strong climbers and active nocturnal hunters. Captive-bred lines often adapt well to enclosure setups and consistent routines, especially in later generations such as F3.

Special Considerations: Tokays possess strong jaws and territorial instincts. Enclosures must be secure, and handling should be minimal.

Taxonomy Note

The Tokay Gecko belongs to the genus Gekko, a group of large arboreal geckos from Southeast Asia known for their bold coloration, vocal nature, and strong climbing ability.

Genetics Note

“3rd Generation Captive Bred” refers only to lineage, not to a morph or genetic mutation.
It indicates that:

• The gecko is F3 (third filial generation)

• Both parents and grandparents were captive bred

• No wild-caught animals are present in the immediate lineage

This generally results in:

• More consistent health

• Animals better adapted to captive conditions

• Reduced stress response compared to wild-caught individuals
