The vibrant and unusual-looking tokay gecko (Gekko gecko) is a well-known, but poorly understood, species. Heavy-bodied and nocturnal, these tropical animals have a reputation for being aggressive, hard to handle and apt to bite. However, they can be the ideal captive for a patient geckokeeper. They are fascinating to observe, and with a little invested time, they can be tamed into tractable little beasts.
Tokays require high humidity and good ventilation. They will not survive in a constantly wet or damp environment. High humidity with inadequate ventilation can cause fungal or bacterial issues. They must be able to dry out, but if kept too dry, they suffer from stuck sheds, which can be difficult to remove, especially around the toe pads. Keep humidity between 60 and 80 percent, and use a screen cover that allows the cage to breathe.
