I just got my first Crested Gecko on Saturday. And I feel bad that it (I don't know the sex yet) is in the tank all alone. So my question is do they prefer to have a pal or would my gecko thank me for being left to have the tank (~17 gallons) to itself? I don't plan to breed at this point so would wait until I knew the sex and if a female I would get another female....if male, not sure if I would want to have a potential breeding pair or not. Anyway, what are thoughts on whether they prefer to be alone or have a "friend".
