I would personally maintain them in nature identical conditions, similar to the habitat they were sourced from.
Different populations of the same species, found in disparate locations are often adapted to local environmental conditions, especially in terms of humidity and temperature, which also influence their daily activity and movement (which, once again, varies as per seasonal changes).
I have personally observed this in Geckoella deccanensis. The ones found in my city, inhabiting a mixed-moist deciduous type forest seemed to have relatively low humidity requirements, whereas the ones inhabiting a montane evergreen forest, 90 kilometers away, at an altitude of of around 800 m (2,625 feet) above sea level seemed to distinctly prefer significantly higher humidity levels.
Sincerely,
