Tokay gecko: what a study on pair housing changes about setting up the terrarium
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
The Tokay gecko (Gekko gecko) has a reputation as a territorial animal with little tolerance for cohabitation, which makes the question of pair housing a particularly sensitive one. A study by Szabo, published in 2024 in the journal Applied Animal Behaviour Science, tracked enclosure use and thermoregulation behaviour in Tokay geckos before and after they were paired up (see the study).

A measurable shift in how the heat mat gets used
Once paired, females were found on the heat mat more often ahead of their first clutch, and their thermoregulation behaviour became more consistent and predictable over time. This finding suggests that having a partner tangibly changes how the animal uses its terrarium's thermal space, not just its social behaviour.
A cohabitation that stays far from automatic
The study also notes that Tokay geckos are choosy about their partner and can show marked aggression toward an individual judged unsuitable, which sometimes means testing several pairings before finding a couple that cohabits without tension. Introducing a pair without close monitoring in the first days is therefore not without a risk of injury.
Continuous egg-laying, an under-appreciated point to watch
Another practical finding: a female kept as a pair can start laying eggs almost continuously, which makes it harder to maintain good body condition and sharply raises calcium requirements. Increased calcium supplementation and regular weight monitoring then become necessary, far more so than for a female housed alone.
What this means for the setup
Considering pair housing for Tokay geckos therefore calls for a terrarium large enough to offer several hides and several thermal zones, letting each individual retreat when needed, along with close monitoring in the first weeks rather than simply introducing the pair and leaving them unobserved.
- Main finding: more frequent and more regular use of the basking spot by paired females, especially ahead of egg-laying.
- Documented risk: selectivity and possible aggression toward a poorly matched partner.
- Physiological consequence: near-continuous egg-laying when paired, with increased calcium needs.
- Good practice: a spacious terrarium with several hides, close monitoring during the first days of cohabitation.
This cohabitation question connects with our general notes on housing two reptiles in the same terrarium, and complements our guide to quarantining a new reptile before any introduction.
FAQ
Can two Tokay geckos be housed together without risk?
It is never guaranteed to be risk-free: close monitoring remains essential, with the ability to separate them quickly at the first signs of aggression.
Does a paired female need more calcium than a solitary female?
Yes, more frequent egg-laying markedly raises calcium needs; suitable supplementation and an exotic-animal vet's follow-up are recommended.
Should several partners be tried before finding a compatible pair?
That is often the case with this choosy species; it is better to plan for that possibility than to expect immediate compatibility.
