Tokay Gecko (Gekko gecko) Care Sheet
A complete guide for the successful keeping of this large, highly vocal, and notoriously defensive arboreal gecko from Southeast Asia.
1. Overview & Natural Habitat
-
Common Name: Tokay Gecko
-
Scientific Name: Gekko gecko
-
Natural Habitat: Humid tropical and subtropical rainforests across Southeast Asia. They are strictly arboreal (tree-dwelling) and often inhabit cliffs, caves, and sometimes human dwellings.
-
Size: One of the largest gecko species; adults typically reach 30 – 40 cm (12 – 16 inches) in total length.
-
Lifespan: Can live 15 – 20+ years in captivity.
-
Temperament: Highly defensive and aggressive. They are known for their strong bite and loud, territorial “Tokay! Tokay!” vocalizations. They are nocturnal. They are generally considered a display-only pet and are not recommended for beginners.
2. Vivarium/Enclosure
Tokay Geckos are large, active climbers and require a substantial, tall enclosure that is heavily furnished.
-
Minimum Enclosure Size (Adult Pair): Due to their large size and territorial nature, a single adult requires a minimum of 60 x 60 x 90 cm (24 x 24 x 36 inches). A pair requires an enclosure significantly larger: 90 x 60 x 120 cm (36 x 24 x 48 inches) or larger.
-
Enclosure Type: Glass or PVC vivariums are suitable, as they retain the high humidity required. Enclosures must be secure and escape-proof.
-
Structure: Must be densely furnished with cork bark tubes, thick bamboo poles, sturdy branches, and abundant large-leafed artificial or live foliage for cover. Vertical structure and hiding places are essential.
-
Hides: Provide multiple dark, secure vertical and horizontal hiding spots high up in the enclosure. Cork tubes or PVC pipe sections make excellent secure, tight hides.
3. Substrate
The substrate must be able to retain moisture to maintain the high ambient humidity.
-
Recommended Substrate: A deep layer (at least 5 – 10 cm or 2-4 inches) of moisture-retaining material such as Cypress Mulch, Coconut Fiber (Coco Coir), or a Bioactive Soil Mix (soil, sphagnum moss, bark).
-
Substrate Management: Substrate should be kept consistently moist (not soggy) and spot-cleaned daily.
4. Heating & Temperature
Tokay Geckos are tropical and require stable, warm conditions without excessive heat that could cause stress.
-
Primary Heat Source: An overhead heat source, such as a Deep Heat Projector (DHP) or a low-wattage Ceramic Heat Emitter (CHE), connected to a dimming or pulse proportional thermostat, is ideal.
-
Basking Surface Temperature (Warm Spot): 30°C – 32°C (86°F – 90°F). This should be measured on a high basking surface like a cork flat.
-
Cool Ambient Side: 24°C – 27°C (75°F – 80°F).
-
Night Time Temperatures: Temperatures should ideally not drop below 22°C (72°F).
-
Crucial Safety Tip: All heating elements must be connected to a Thermostat to prevent overheating. Use digital thermometers with probes for accurate readings across the gradient.5. Lighting & UV
While nocturnal, low-level lighting and UVB are both beneficial for health and natural behavior.
-
Ambient Light: Provide an ambient light source (like a low-wattage LED) on a 12-hour cycle to simulate daylight.
-
UVB Light (Recommended): A low-level UVB source (e.g., a 5-6% T5 linear fluorescent tube) is recommended to aid in Vitamin D_3 synthesis, even for a nocturnal species.
-
Photoperiod: Maintain a consistent 12 hour day/12 hour night cycle.
6. Humidity & Hydration
High, consistent humidity is crucial for the Tokay Gecko’s health and successful shedding.
-
Ambient Humidity: Must be maintained in the range of 60% to 80%.
-
Misting: The enclosure must be thoroughly misted once or twice daily, typically in the evening and lightly in the morning. This is necessary for providing drinking water (they lick droplets) and maintaining humidity.
-
Water Dish: A large, shallow water dish should be provided on the floor, though they primarily drink droplets.
-
Ventilation: While high humidity is required, good ventilation is equally important to prevent stagnant air and bacterial/fungal growth.
7. Diet & Feeding
Tokay Geckos are highly opportunistic insectivores and can eat surprisingly large prey.
-
Staple Diet: Large Crickets, Cockroaches (Dubia/Discoid), and Giant Mealworms. They will also readily take pinky mice (sparingly, as a rare treat only) and occasional prepared Crested Gecko Diets (CGD) for variety.
-
Feeder Size: Prey can be large—up to the size of the gecko’s head.
-
Feeding Schedule: Offer appropriately sized prey items every 3-4 days.
-
Supplementation Schedule:
-
Calcium Powder (Pure): Dust insects at every feeding.
-
Calcium with D_3 and Multivitamin: Alternate use as directed by the product instructions (e.g., D_3 1-2x a month, Multivitamin 1x a month).
-
-
Gut Loading: All feeder insects must be fed a nutritious diet (gut loaded) for 12-24 hours prior to feeding them to the gecko.8. Handling & Temperament
-
Temperament: Tokay Geckos are not suitable pets for handling. They are highly defensive, territorial, and will bite readily and hang on fiercely. They are strictly display animals.
-
Handling: Only handle a Tokay if absolutely necessary (e.g., vet visit, enclosure cleaning) and always wear thick gloves. Avoid cornering them; if you must move them, encourage them to step into a catch cup or plastic container.
-
Vocalization: Be prepared for loud, guttural warnings and the characteristic “Tokay! Tokay!” call, usually heard at night.
That is a comprehensive and cautious care sheet for the challenging Tokay Gecko.
