Factors affecting a Bearded Dragon’s Longevity

Like all other species, bearded dragons can live long or not depends on many factors. Of which, the most important ones are the diet, species classification, surrounding environment, and gender.


Usually, more massive bearded dragons will live longer than small ones. They eat, sleep, function healthier, and have better stamina. In the wild, more giant individuals can run faster and avoid predators.

And this is also true when we compare among species of the bearded dragon. In particular, species with superior body size and length will have a more significant lifespan.


When you provide all the necessary nutrients for bearded dragons, of course, they will always be healthy and happy.

The main foods of bearded dragons are mealworms, superworms, crickets, dubia cockroaches, and vegetables. Vegetables include mustard greens, water spinach, katuk, crested latesummer mint, tomatoes, rose petals, and leaves, etc.

For tubers, you can choose carrots and potatoes for them. Besides, some of the bearded dragons’ favorite fruits include mango, apple, pear, custard, watermelon, rambutan, and papaya, etc.

Notably, with vegetables that are too big, they need to be cut small enough for bearded dragons to eat. This is very important because, if the food pieces are more significant than the distance between the pets’ eyes, it can lead to severe consequences such as gastrointestinal obstruction and leg paralysis.

For baby bearded dragons, their diet consists of 80% small insects and 20% vegetables. As they get older, let’s gradually change them to 65% vegetable and 35% insects.

After the bearded dragons are done eating, you need to clean up the leftovers because they can produce lots of bacteria.

Moreover, let’s make their living conditions as pleasant as possible by changing their diet regularly. They will find it tastier, and you can tell which one they like best.

Besides the primary food source, you also need to supplement them with vitamin D3, calcium, and essential minerals.

Living condition

Building a stable and fully-equipped cage is an essential thing to do before adopting the pet. The barn will protect this species from predators, which bearded dragons do not have in the wild.

The cage needs to be large enough for bearded dragons to move depending on their age and body size. They do not run around much, but they have the instinct to burrow and hide.

In particular, the cage size for adult bearded dragons should be 65 cm wide and 50 cm high.

In hot desert environments of 50-60 degrees, caves, bushes, and rocks are the best places for bearded dragons to avoid heat. Therefore, in their cages, you should equip these items.

And most importantly, choose to buy the best bearded dragon substrates. There are many types for you to choose from, each of which has its own advantages and limitations.

While the sand is considered to be not suitable for bearded dragons’ digestive system if they accidentally ingest, they are very beneficial for burrowing. As for carpet substrates, they have better moisture and smell absorbency. In addition, you have other options, including coconut fiber, newspapers, or ceramic tiles, etc.

Last but not least, in the cage of bearded dragons, the heaters and UVB light bulbs are indispensable. This is a tool to help them supplement vitamin D and calcium instead of taking them from sunlight.

But do they still need to sunbathe? Definitely.

You should let your pet contact the sunlight regularly in the morning (about 45 minutes every 2 days a week).

At the same time, the heaters and light bulbs also have a role in keeping the humidity in the cage always at a low level, avoiding harmful bacteria produced. The appropriate temperature in the enclosure should be 25-31 degrees Celsius in daytime and lower at night, about 21-26 degrees Celsius.


It is one of the bearded dragon fun facts that male bearded dragons will have a longer life span than females.

This is crazy:

The main reason for this difference is breeding. Hence, you should not allow bearded dragons to conceive after three years of age.

Otherwise, after laying eggs, the mother will have a significantly reduced life expectancy, and the babies will hardly be healthy.

Common Diseases of Bearded Dragons

There are two leading causes of several common evil bearded dragons’ conditions, including poor-quality food and habitat. And their diseases are listed below.


This is a common disease in this species because they live depending a lot on the ambient temperature. If the living space is not warm enough, it will affect their digestive system and cause indigestion.

The sign that you can recognize this disease is that they do not excrete despite eating well. You just need to adjust the temperature in the cage and stimulate digestion by soaking the pet’s body in water for 5-10 minutes per week.

Dehydration disease

If you notice that your bearded dragon has signs of sunken eyes, wrinkled skin, he does not want to eat and becomes more agile after drinking water, and then he is dehydrated.

In this case, you need to replenish drinking water for him, whether he wants it or not.


As we have warned, the large size of food will lead to paralysis of the legs of this species. Therefore, you should pay more attention when preparing food for them.

Metabolic bone disease

When you see your pet having seizures, tremors, a bump in the leg or lower jaw, then he is deficient in calcium, vitamin D3, and phosphorus. That is the cause of metabolic bone disease.

Therefore, you need to regularly supplement these nutrients for them, from food to light bulbs or to sunbathe.

Dry-eye disease

Bearded dragons’ eyes are also very susceptible to infections, which can cause the eyes to collapse. It is a sign of dry-eye disease. In this case, you should take the animal to see a veterinarian for treatment. Also, make sure your pet’s cage and food are clean, not damp.

Too much in anything is always not good, including vitamin A. If you think that a bearded dragon with an overdose of vitamin A is no big deal, you are entirely wrong.

It can cause injuries such as swelling of the eyes, throat, body edema, and bearded dragons won’t have the energy to function.

FAQs on Bearded Dragon’s Longevity

What is the longest living bearded dragon?

About interesting bearded dragon facts, there have been opinions that bearded dragons can survive for up to 20 years in captivity. However, this is still not certain, and there are no specific cases about that.

Ideally, you should spend some time to take care of your pet and provide the necessary supplies and food for them. As such, they can live happily ever after with you.

How quickly do bearded dragons grow?

A bearded dragon reaches the most significant size at about 45-55 cm. Some individuals may be up to 60 cm.

The time it takes for them to reach their maximum size is three years.

Therefore, with mature bearded dragons, every day, you should only feed them insects once and plenty of green vegetables.

Also, as they grow, you may notice their process of skinning. Bearded dragons shed their skin about once every 3-4 months, while the younger do this every 2-3 weeks.

Which signs indicate that your pet is happy?

There is no specific body language proving that your bearded dragons are having fun. But as long as you see them eating, sleeping, and functioning normally, it means they are having no problems with negative emotions.

A bearded dragon flattening out

There are many reasons that you should worry when your pet flatten up.

Firstly, maybe he’s experiencing fear and defending by making himself look more prominent. He will flatten the tummy along with discolorating the body and inflating his throat.

Secondly, he may be hungry or ill. Therefore, he has no energy to move but lies with a flat body. Calcium imbalance is also a common cause in this case.

Do bearded dragons get lonely?


Bearded dragons are independent species. In other words, they don’t live with herds. Therefore, it’s fine if you pet one bearded dragon alone.

If you own a bearded dragon, you should bathe them once a week. Remember that they cannot swim, so you need to prepare a bowl of shallow water. The water level needs to be lower than the distance from its eye to the ground.

Build them a tank that is large enough for them to move around and play. If possible, you can make a terrarium or aquarium. In the tank, there should be enough items, as we mentioned above, such as substrate, stone, twigs, lounger, bathwater, food, drinking water, bearded dragon toys heaters, and light bulbs, etc.
