Do Crested Geckos Need UVB?

Creating the ideal environment for your crested gecko is key to keeping them healthy and happy. Factors like the correct kind of lighting are essential in ensuring your gecko’s habitat is comfortable for them. But does your crested gecko need UVB?

Crested geckos don’t need UVB lighting in their habitat, but it can still be beneficial. Crested geckos are nocturnal animals, so UVB is not required, but many reptile owners argue that UVB will keep your crested gecko more active and improve their health.

In this article, we’ll be going in-depth into why crested geckos don’t need UVB, the health benefits UVB lighting can have on your reptile friend, and the kind of lighting your crested gecko actually needs. If you’re interested in learning more about these topics, keep on reading.

Why Don’t Crested Geckos Need UVB Lighting?

As we stated above, these geckos are nocturnal animals and don’t need UVB lighting to survive. While UVB is something that crested geckos naturally absorb in the wild, it’s not necessary to assemble this kind of lighting for your gecko’s tank.

In the wild, geckos are able to absorb nutrients like calcium through UVB light, but many of the foods available for your crested gecko also contain the same kind of nutrients. Vitamins like D3 keep your gecko happy and healthy and can be consumed without the use of UVB.

A great way to ensure that your crested gecko will receive all the nutrients it needs is by using calcium supplements. These will keep you crested gecko at their healthiest, and products like the Zoo Med Repti Calcium Reptile Supplement will do just that, and all you have to do is sprinkle a small amount of this mixture onto your gecko’s food.

Another reason crested geckos don’t need UVB light to survive is the fact that these reptiles are actually quite sensitive to UVB. Long periods of heat and light are not the best for your animal, so it’s important to be mindful of how much exposure they’re getting.

Investing in a UVB light for your gecko’s tank is not a necessity, as your gecko can continue to grow healthy and strong without one. However, we will be discussing the multiple benefits that UVB light can give your reptile if you choose to use it.

Benefits of UVB on Your Crested Gecko

While we discussed how a lack of UVB wouldn’t hurt your gecko, actually having UVB light available is likely to improve multiple factors of their health.

It Encourages Natural Behaviors

Studies have found that when reptiles are exposed to appropriate amounts of UVB light, it can encourage natural behaviors such as climbing, digging, and making noises. It is suggested by experts that a low level of UVB lighting, somewhere around 5%, should be used for your gecko’s tank if you plan on using UVB.

As we discussed earlier, too much heat and light can cause discomfort and future health problems for your reptile, so it’s important to be mindful of how much UVB your gecko is subjected to.

If you choose to give your crested gecko access to UVB, somewhere between 4-6 hours per day is all your reptile friend needs to gain all the benefits that come from this form of lighting.

It Provides Numerous Health Benefits

Not only does UVB supply your gecko with nutrients like calcium, but UVB will also strengthen your gecko’s immune system, as well as bone, vision, and blood health.

If you’re looking for the ideal UVB lighting fixture, this Zoo Med Mini Tropical UVB is a great option for you and your reptile. Setting this UVB light fixture above your gecko’s enclosure will allow your reptile to soak up all the necessary nutrients and light.

While your crested gecko can survive and be healthy without being subjected to UVB rays, there are plenty of health benefits to implementing UVB light into your crested gecko’s habitat. So while crested geckos don’t need UVB, it can be very beneficial to your gecko’s health in the long run.

What Do Crested Geckos Really Need?

Crested geckos may not need UVB light to survive, but we did discuss the pros and cons of UVB rays and what you should be aware of before you subject your reptile to it. But unlike UVB, what other factors do crested geckos need to survive and stay healthy?

A Large Tank

One of the most important tools that your crested gecko will need to stay safe and healthy is a proper tank. A tank of the correct size will ensure that your reptile will have plenty of room to act out their natural behaviors, as well as keep them comfortable and happy.

This Exo Terra Nano Glass Terrarium is highly recommended and is an appropriate size for a gecko of any age or size. Housing your gecko in a quality tank is one of the first steps in ensuring your crested gecko has a safe and happy home.

The Right Amount of Food and Water

Another factor that is a must for your reptile is the proper amount of food and water. Water should always be available within your gecko’s tank, and feeding schedules should be consistent in order for you and your gecko to maintain a set schedule.

As for the water in your gecko’s tank, it should be replaced every 24 hours, so bacteria does not begin to build in and around your crested gecko’s water bowl. As for feeding schedules, it really depends on the size and shape of your gecko in terms of how often they are fed.

Baby crested geckos should be fed everyday, unlike adult crested geckos, which should be fed around 2-3 times a week. It’s also important to be consistent when feeding your geckos, as practicing feeding schedules at the same time and day is important to keep your gecko healthy and on a set schedule.

Tank Furniture and Decor

Crested geckos also need appropriate items within their tank, such as plants and other interactive forms of decor. Plants and vines allow your gecko to perform natural behaviors such as climbing, which is definitely a benefit to the health of your gecko.
