Tokay gecko: what a study on pair housing changes about its enrichment
The tokay gecko has long been described as an aggressive loner that must always be kept isolated, but a recent study precisely compared its behaviour when living alone versus in a pair, with results that invite some nuance to this reputation. Our enrichment guidance is gathered in the reptile toys and enrichment section.
A study on pair housing in the tokay gecko
Birgit Szabo published a study in 2024 in Applied Animal Behaviour Science on changes in enclosure use and basking behaviour associated with pair housing in tokay geckos (Gekko gecko) (study on Google Scholar). Comparing individuals housed alone and then in pairs, the researcher measured that geckos deprived of a companion moved and hid more as the keeper approached before feeding, while pair housing reduced this flight response to human presence.
What this changes about terrarium enrichment
This result, measured over several weeks, challenges the common assumption that every tokay gecko should live in isolation to avoid conflict.
- Consider a compatible pair housing setup (a male and a female, never two males) in a terrarium large enough to offer several hiding spots, rather than defaulting to isolation.
- Add plenty of hides and elevated perches so each individual can move away from the other at will, even while cohabiting.
- Watch for signs of real conflict (biting, refusing food, prolonged immobility) rather than assuming social stress from cohabitation alone.
This social enrichment angle builds on the practical guidance in our article on transporting a tokay gecko, and pairs with our guide on terrarium branches and vines, essential for this arboreal species.
Frequently asked questions
Can two male tokay geckos be housed together?
No, both the study and breeders' experience show that two males are aggressive toward each other; only a male-female pair or a solitary female is workable for cohabitation.
Does pair housing remove all stress linked to humans?
No, but the study measured a reduction in flight behaviour toward the keeper in pairs compared with isolated individuals, a welfare signal worth noting.
Does an already-solitary tokay gecko need to be paired up?
Not necessarily: a single individual in a terrarium rich in hiding spots can do perfectly well; pairing remains an option to weigh against available space and individual compatibility. Find all our guides on the reptile hub.
