Crested Gecko Lifespan in Captivity: How Long Crested Geckos Live in Captivity?

In captivity, crested geckos have a long lifespan, which ranges from 15 to 20 years. Some researchers estimate that they can live for about 30 years. However, numerous factors can influence their lifespan like care, genetics, and diets.

The Case for Keeping Crested Geckos

Physically, crested geckos are magnificent, and they always fascinate reptile lovers and everyone else.

Cresties have a perfect combination of cuteness and beauty. They come in a wide range of colors, from charcoal to vivid red. Another magnificent thing is that it colors up at night. You do not need a large enclosure for them as they grow to about 6-8 inches long.

They have velvety soft skin with tiny claws that can never hurt. Their faces are comical, and their eyes are covered with tiny ‘eyelash’ scales.

Interesting crested gecko fact: Unlike most other geckos, crested geckos cannot regenerate a new tail.

A slight advantage of crested geckos over leopard geckos and bearded dragons is that it is easy to set up their tank. They are a friendly lizard but are flighty and will fly from one object to another.

Although they do not like to be handled, they will put up with an adequate amount of handling.

Little information is known about crested geckos in the wild. Since they were rediscovered in 1994, cresties have been bred in captivity. However, crested geckos are native to New Caledonia, a block of islands off the Australian coast.

In the wild, they are semi-arboreal and nocturnal reptiles and will feed on fruits and insects. They prefer to sleep in a hidden spot on the ground or under cover of low tree branches in the day.

Cresties love leaping among the trees and getting most of their water from licking the raindrops off leaves.

At night, crested gecko feeds on fruit that has softened on insects or the forest floor. They also feed on moths, crickets, spiders, and other insects throughout the forests. They chirp or bark to communicate with other cresties or to ward off predators.

Feeding your cresties with a healthy diet is essential for their wellbeing and lifespan.


You will find a wide range of reputable brands that make commercial crested gecko food that will give your crested geckos all the nutrients that it needs. There are two types of commercial crested gecko food available in the market. They are:

Meal Replacement powders (MRP): This type of crested gecko diet is produced in powder form, and it will then be mixed with water to form a paste.

Granules/pellets: This crested gecko diet is produced in little ball-shaped granules form, and you can just feed your cresties directly with it.


Both in the wild and captivity, crested geckos love to hunt for insects and worms. Insects are a protein source for geckos and ensure they are not larger than the distance between your gecko’s eyes. Some of the popular insects and worms that you can feed cresties are crickets, dubia roaches, mealworms, super worms, waxworms, etc.

Dietary Supplements

When feeding your cresties with insects and worms, there is a need to gut-load or dust them with dietary supplements.

Gut loading involves feeding the insects with supplements a day before you feed them to your cresties. While dusting means coating the insects with supplements before you feed them to the gecko.

Food to Avoid – What You Should NOT Feed Your Cresties

Here are some of the food that can affect the lifespan of crested geckos, they are:

Baby Food

Fruit-based baby foods can be used to replace fresh fruit for your crested geckos. However, baby food comprises high amounts of sugar, additives, and preservatives, which can be bad for geckos. This is why it is best to avoid this and use a healthy alternative diet for your cresties.

Large Insects

Insects are a perfect diet that you can use to feed your gecko. But you will need to ensure that the insects are not too big for them. Feeding with a large insect can lead to constipation problems for your gecko.

Citrus fruits

Citrus fruit is considered harmful for cresties due to the presence of citric acid. You can only give them to your gecko as treats and ensure it is once in a month.

Wrong Diet In Young Crested Geckos

Feeding of baby crested geckos starts after their first shedding. You can feed them with commercial crested gecko food or a self-made fruit diet. However, feeding your young cresties with the wrong diet can lead to health issues for them in the long run.

Feeding of crested geckos with the wrong diet can cause stunted growth, tiredness, weight loss, floppy tail, soft bones, etc. This can then lead to severe health issues if it is not corrected.

Impaction in Crested Geckos

This occurs when your crested geckos feed on small or large objects that do not digest and get stuck in their intestines. Impaction is common in hatchlings and juvenile cresties as they are prone to swallowing substrate. To avoid impaction, it is best to keep hatchlings and juveniles on paper towels.

Symptoms of Impaction

  • Rapid weight gain
  • Appetite loss
  • Irregular pooping
  • Your gecko has a plump belly that looks very round.

Metabolic Bone Disease in Crested Geckos

This health problem occurs when you do not feed your cresties with enough Vitamin D3 and calcium. It is common in breeding females and young gecko because they need higher levels of calcium.

Symptoms of MBD

  • Soft jaw
  • Deformed limbs
  • Weakness and reduced mobility
  • Appetite loss
  • Humped back
  • Female cresties look tired and lifeless after laying eggs
  • Kinking of the tail and spine
  • Calcium sacs in the mouth become pale, flat, and almost invisible in adult gecko.

Treating Metabolic Bone Disease

You can only treat mild cases of MBD in crested geckos. Severe cases of MBD can cause irreversible damage. It is best to act immediately when you notice the symptoms related to MBD in your gecko.

Feed them with calcium and vitamin D3 supplements once you notice signs of MBD. You can also take them to a vet for expert advice on ways of treating the disease.

Crested geckos are prone to infections since they crawl all over the surface. Some of the common infections that can affect your gecko lifespan are stated below

Cryptosporidiosis: This infection can lead to death if untreated as it can cause digestive issues, weight loss, and malnutrition. Although this infection often infects leopard geckos rather than cresties. However, if you notice worms in the poop of your gecko, quarantine it immediately in a simple container with paper towels.

Salmonella infection: Salmonella is a bacteria that lives in the gut of reptiles. They do not cause issues for cresties, but you can contact them.

Note: internal parasites in high numbers can lead to diarrhea, loss of appetite, weight loss, dehydration, etc.

External Parasites in Crested Geckos

Although this does not happen very often, your cresties might get infected with mites. It is hard to remove mites and will take some time before you can clear the infestation. Some of the methods used for removing mites are mite spray, cotton buds dipped in oil or alcohol, or manually.

Vitamin Issues in Crested Geckos

Vitamin issues in crested geckos can be caused by low vitamin or excess vitamin in their diet. This can affect the lifespan of cresties as it leads to several health complications.

Hypervitaminosis A

Hypervitaminosis A is a nutritional disorder caused by an excess amount of vitamin A and can be induced by injection of vitamin A to reptiles with hypovitaminosis A. Clinical signs of hypervitaminosis A usually manifest on the skin. You will see signs like dry and scaly skin, skin ulceration, lethargy, weight loss, anorexia, and/or dehydration.


Hypothiaminosis is a nutritional disorder, also known as thiamine deficiency. Although this is not common in crested geckos, it can be found in animals fed thawed freezing fish, vegetation, and clams.

Some of the signs of hypothiaminosis in reptiles are muscle twitching, blindness, incoordination, abnormal posture, and can even lead to death. Affected reptiles may also not be able to strike their prey accurately.
