Building or buying a housing unit for a Gecko is one thing, but you want to make sure that your Gecko is living in adequate temperature as well. You don’t want your Gecko to be cold or too hot, but remember that they’re from warm habitats. The common and basic temperature all year round should be anywhere from 72 to 80 degrees. The leading cause of depression which leads to death in Geckos is because the temperature is far too warm which is usually 90 and above. Most of the year, they’ll prefer that the temperature be somewhere in the mid-70s.
What happens is, they become sick or ill and they stop eating or doing anything. It’s the opposite reaction that humans have to becoming stressed because when the majority of humans become stressed, they tend to eat more than normal. However, when Geckos become stressed, they stop eating altogether usually until they die from a lack of food or nutrients.
While Crested Geckos can tolerate moderate temperature drops in the night time, this isn’t necessary. You commonly won’t see your gecko during the day time anyways as they like to come out at night, they’re very nocturnal. So you’re not advised to provide any kind of drop down in temperature, it’s best to just leave it as it is.
If you have breeding crested Geckos, then you might want to give them at least one month a year where they do cool down a bit to help ensure that breeding is successful. The temperature during this time can go down to 65 degrees but it’s not recommended that you go any lower than that. Usually, they get about 12 hours of light a day which is a completely acceptable amount of light. However, during their resting or cooling period which can be one to two months, they’re going to require only 10 hours of light or you might be able to get away with less.
When it comes to lighting, you can do this by using fluorescent lights. Most people prefer to put them in the middle of the cage hanging from the top. Not only does this serve a purpose for the Geckos but also live plants in the cage will get their daily light as well. You don’t have to use UVB lighting as some guides have suggested although it really doesn’t hurt. If you have a rather large collection of crested Geckos, you more than likely know what you’re doing but you should make sure that there’s plenty of artificial and natural light coming into their enclosure or area.
The problem with breeding is that if they’re given any less than 12 hours of light, they’ll stop laying eggs and they may stop breeding altogether, so try to make sure they’re given 12 hours of light at minimum. Just remember, that the perfect temperature is between 70 to 80 degrees and shouldn’t go under or above this unless they’re in the cooling period then 65 degrees is adequate.
If you’re having trouble keeping your temperatures in an appropriate and efficient range to raise or breed your Gecko, consider getting a nocturnal black heat light to add to the cage. It can just hang there for 24 hours without a problem and it won’t overheat the enclosure. Nocturnal viewing is also helped greatly when you put one of these in.
