Overview

What is this animal?

  • 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.

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.
Show 4 more
  • 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

Enclosure

Minimum 4 sq ft of floor · 24 x 24 x 47 in

Must be housed alone. Solitary; house singly

  • House one adult in a tall, well-ventilated, securely latched vivarium of at least 24 x 24 x 48 in (35 x 24 x 47 in for a particularly large adult), 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 82-86°F with a basking area near 90°F and cooler shaded zones, plus a nighttime drop.
Show 2 more
  • 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.

Care in depth

Diet

Insectivore (live insects, occasional pinky)
  • 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 juveniles daily and adults every other day, offering as many insects as the gecko will eat in about five minutes, none larger than its head; a pinky or a little complete gecko diet is a treat, no more than twice a month.
  • Provide fresh water in a dish, though they drink mostly from misted droplets on leaves and glass.

Health

Signs of good health, and the common problems
  • 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.

Is this urgent?

4 warning signs and how fast to act, 1 of them right away

Small geckos dehydrate and lose condition quickly. Weight is the fuel gauge, and in leopard and African fat-tailed geckos so is the tail.

Go now

Tremors, weak grip, or a jaw that will not close properlyGo now. Calcium and D3 deficiency.
Now

Today

Tail visibly thinning in a species that stores fat thereWeigh, then call with the trend. The fat store goes before the body condition does.
Today
Stuck shed around the toes or over the eyesRaise humidity, offer a damp hide, and call if it is not clear within a day. Constricting shed rings cost toes. This is the most common avoidable injury in geckos.
Today
Refusing food with weight lossCheck the cool-end and warm-end temperatures, then call. A gecko that cannot reach its preferred temperature cannot digest.
Today

This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it, and the time to find one is before you need one.

Bedding and substrate

3 safe, 1 with a caveat, 3 to avoid

Match the substrate to the species' humidity, and never let a small gecko stand on anything it can swallow whole.

Safe

Topsoil and play sand mix for arid geckosPacks firm, holds a burrow, and is what a leopard gecko would actually stand on.
safe
Coco fibre and orchid bark for tropical geckosHolds the humidity a crested or day gecko needs.
safe
Paper towelCorrect for quarantine, for hatchlings, and for any animal whose output you are watching.
safe

With a caveat

Sphagnum mossExcellent in a humid hide, poor as a whole-floor substrate: it stays wet.
with a caveat

Never

Calcium sandSold as digestible, which is exactly why it gets eaten. Implicated in impaction.
never
Crushed walnut shellSharp and indigestible.
never
Loose play sand alone for hatchlingsToo easy to swallow at that size.
never

Ground-dwelling geckos such as leopard and fat-tailed geckos need a humid hide whatever the main substrate is, and most of their stuck sheds trace back to its absence. Arboreal geckos get their shedding humidity from misting the whole enclosure, so stuck shed in them usually means the enclosure is too dry.

Is your enclosure big enough?

These are the smallest sizes that give good conditions, not legal minimums. More room is always better.

What it really costs

Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.

Can a Tokay Gecko eat that?

Tokays are voracious insectivores: large live insects, with a pinky or a little fruit-gecko diet as a treat at most twice a month.

The full list: 23 foods

Never (14)

AlcoholNo safe amount at any body weight on this site.
never
AvocadoPersin.
never
CaffeineCoffee, tea and energy drinks. Cardiac and neurological toxicity at tiny doses for an animal this size.
never
ChocolateTheobromine and caffeine. Small mammals and reptiles cannot clear either.

CitrusAcidic enough to upset the gut, and sugary. Not worth the risk.
never
FirefliesLucibufagins. Fatal to geckos.

GarlicSame allium toxicity as onion, and more concentrated by weight.

Insects larger than the gap between the eyesA recognised cause of impaction and neurological injury in small geckos. Size the feeder to the animal, every time.

Occasional (3)

HornwormsHigh water content; useful for a dehydrated animal. One occasionally.

Everyday foods (3)

Black soldier fly larvaeHigh in calcium, and readily taken. Several per feed.

CricketsStandard feeder. Gut-load for 24 hours before offering. Sized to the eye gap.

That food is not on our list. Check which kind of gecko you have first (the two diets barely overlap), then ask an exotics vet.

Dust feeders with calcium and a vitamin and D3 supplement on a regular schedule.
