The Tokay gecko, from the forests of South and Southeast Asia, is one of the largest and most striking geckos, blue-grey with orange and white spots and named for its loud 'to-kay' call.
It is bold, fast and famously defensive, delivering a powerful, tenacious bite, so it is firmly an advanced, hands-off species.
Despite their difficult temperament, Tokays are hardy and long-lived when their humidity and space needs are met.
Many sold are still wild-caught and arrive stressed or parasitised, so captive-bred animals and a quarantine plan matter.
They suit experienced keepers who want an impressive vivarium occupant to observe, not to handle.
Housing
House one adult in a tall, well-ventilated, securely latched vivarium of at least 60x45x90cm, well furnished with cork bark, branches and live plants for climbing and dense cover.
As a strong arboreal climber it needs vertical space and many hiding spots to feel secure and reduce defensive displays.
Maintain a warm gradient of around 28-30C with a basking area near 32C and cooler shaded zones, plus a nighttime drop.
A low-output UVB tube is beneficial.
Keep humidity high, around 60-80%, by misting daily, while ensuring good ventilation so the enclosure dries partly between mistings and avoids stagnant, mouldy conditions.
Diet
Tokay geckos are voracious insectivores.
Feed a varied diet of gut-loaded, calcium-dusted live insects such as large crickets, dubia roaches and locusts, with the occasional appropriately sized pinky mouse for large adults.
Their size means they take substantial prey, so match insect size to the gecko.
Dust feeders with calcium and a vitamin/D3 supplement on a regular schedule to prevent metabolic bone disease.
Feed adults every few days and juveniles more often.
Provide fresh water in a dish, though they drink mostly from misted droplets on leaves and glass.
Health
A healthy Tokay is muscular and alert with clear eyes, full toe pads and a strong appetite.
Wild-caught animals commonly carry internal parasites and mites and arrive dehydrated, so a vet faecal check and quarantine are wise.
Retained shed, metabolic bone disease and respiratory infections from cold or stagnant humidity are the main husbandry concerns.
Because they are easily stressed, signs of illness such as lethargy, weight loss or laboured breathing can be subtle against their normally defensive behaviour.
Use a vet experienced with exotics, and favour captive-bred stock to reduce disease and welfare problems.
Temperament
Tokay geckos are bold, territorial and highly defensive, gaping, lunging and biting hard when approached, and they will hold on.
They are not a handling pet; interaction is largely limited to maintenance, and even calm individuals rarely become truly tame.
They are also loud, calling at night, which suits some keepers and not others.
They are strictly solitary outside supervised breeding.
Two will fight, often seriously.
A single Tokay in a tall, well-planted vivarium, observed rather than handled, is the appropriate and humane way to keep this species.
A good fit for
Experienced keepers wanting a bold display gecko
Those happy with a hands-off, observe-only reptile
Keepers who can source captive-bred animals
People untroubled by loud nighttime calls
Common mistakes to avoid
Expecting a handleable, tame gecko
Wild-caught stress, parasites and mites
Housing two together (serious fights)
Low or stagnant humidity causing shed and respiratory issues
