Crested gecko: what a study on dominance between females changes about cohabitation
Housing several female crested geckos together remains common practice among breeders, but whether they truly get along is often decided by experience rather than by research. A study by Schaefer, Wetzel, Skalican, Johanson and Loughman, published in 2020 in the Proceedings of the West Virginia Academy of Science, filmed female crested geckos (Correlophus ciliatus) cohabiting in a vivarium for two months to determine whether a dominance hierarchy would form (research on Google Scholar).

A hierarchy that does form
Behavioural analysis of the filmed females revealed the emergence of a dominance hierarchy, with one female gradually establishing herself over the others. This finding confirms that cohabitation between female crested geckos is not simply neutral space-sharing, but an active social dynamic that builds up over the weeks.
What this means for access to resources
An established hierarchy directly shapes access to food, the best hides and the warm spots in the terrarium: the dominant female gets priority access, which can lastingly disadvantage subordinate individuals if the setup does not compensate for this imbalance. A shared terrarium poorly stocked with multiple resources turns cohabitation into a source of chronic stress for the less dominant females.
What this changes about setup
To limit the effects of this hierarchy, multiplying hides, feeding spots and climbing areas lets every female find an available resource without directly confronting a more dominant tankmate. This principle echoes a rule already known in captivity: more resources than individuals in any shared terrarium is always the safer bet, whatever the species.
What this does not excuse skipping
A stable hierarchy forming does not guarantee the absence of open conflict: progressive weight loss, bite marks on the tail or an individual that stays frozen in a corner should raise concern, with separation as a last resort if the situation does not improve despite an enriched setup.
- Main finding: a dominance hierarchy forms between female crested geckos cohabiting for several weeks.
- Direct consequence: the dominant female gets priority access to food, hides and warm spots.
- Practical implication: multiply hides and feeding spots to reduce direct competition.
- Watch for: weight loss, bite marks on the tail or a female staying persistently withdrawn, signs of a poorly tolerated hierarchy.
This cohabitation dynamic complements our guide to setting up an enriched terrarium for crested geckos, and connects with our comparison of crested gecko versus leopard gecko for anyone weighing solitary against group housing.
FAQ
Can a male and several females be housed together?
This study only covers groups of females; an adult male should be kept separate from females outside breeding to avoid constant chasing stress.
Should geckos always be separated once a hierarchy appears?
No, a stable hierarchy with no sign of distress remains compatible with cohabitation; it is mainly injuries or persistent isolation that should raise concern.
Does a bigger terrarium alone prevent conflict?
Size helps, but the study mainly highlights the importance of the number of available resources (hides, warm spots, feeding areas) rather than floor space alone.
