Getting there
Slow, over two years or more
Chahoua are notably slow-growing even by New Caledonian gecko standards. Patience is part of keeping them.
They end up heavier than their relatives
Both longer and more heavily built than crested or gargoyle geckos.
What that size means in practice
A tall, well-furnished vivarium
As the largest of the commonly kept New Caledonian geckos, they need genuine vertical space with sturdy cork and branches.
Prehensile tail changes how they use the space
They grip with the tail as they climb, so branch diameter and arrangement matter more than for a gecko that simply clings.
Common questions
How big do chahoua geckos get?
Adults reach 8 to 10 inches in total length and commonly 45 to 75 grams or more, which makes them larger and heavier than crested or gargoyle geckos.
How long do chahoua geckos take to grow?
Often more than two years to reach adult size. They are notably slow growing even compared with other New Caledonian geckos.
Do chahoua geckos have prehensile tails?
Yes, and they use them actively while climbing. That makes branch diameter and arrangement more important than for geckos that simply cling to surfaces.
