What animals can Tokay geckos live with?

A reptile cannot be housed with a species of a different environment. There would be too many different living conditions to sustain two or more different species. Example: Humidity, temperature, substrates diet etc...

Animals of the same regions can (with exceptions: size of tank, enough food to sustain multiple diets, multiple hiding spots etc..) be housed together. Even in the case of two species being together, they must be monitored, and should only be done by intermediate - expert reptile keepers

In this case the leopard coming from arid deserts of Afghanistan will not be able to co-exist with the high levels of humidity a Tokay gecko would require.
