Normal Crested Gecko Behavior

Crested Gecko Behavior

The following behaviors are normal and you should not be alarmed if you notice them in your Crested gecko.

Sleeping During The Day

A normal Crested gecko behavior is them sleeping during daytime and being active in the evening/night hours. This is completely normal and for crepuscular animals such as the Crested gecko.

If your Crested gecko appears tired and sluggish during the day, it’s normal as that’s their time to sleep.

What Can Go Wrong

What is not normal is your gecko is awake during the daytime hours. If you keep seeing your Crested gecko awake during the day, you need to investigate what is keeping them up. If their tank is near any loud noises such as kids, TV, radio, etc, you should think about relocating their tank.

Sleep is essential for any living creature and if your gecko doesn’t get enough quality sleep, it can get sick.


Another normal Crested gecko behavior is shedding. Like many other reptiles, Crested Geckos shed their skin.

Crested geckos shed when they:

  • Lose weight
  • Gain weight
  • Grow. When your gecko is a baby, it will shed more often as they grow quicker in the first 12 months

When your Crested gecko is about to shed, you will notice that they eat less a few days before and after shedding. Normally, the shedding takes on average 2 days from the moment their skin becomes wrinkly and pale.

What Can Go Wrong

If a gecko has a bad shed, they might need your help to remove the skin or it can result in restricted blood flow. This can result in loss of toes, tail tips or even an entire limb in some rare cases.

To help your Crested gecko shed successfully, you can do the following:

  • Increase the humidity to 80-100% until shedding is done
  • You can place your gecko in a small plastic box/crate/bowl and put a wet, lukewarm paper tower inside. This sauna effect will help the skin come off easier

Eating Skin After Shedding

One weird Crested gecko behavior, that’s also perfectly normal, is your gecko eating their skin after shedding. You might not even notice when this happens as it will probably be during the night when your gecko is most active.

This is a normal behavior. It’s believed that Crested geckos eat their skin for two reasons:

  • To get nutrients from the skin
  • So they don’t leave any trace for predators

Licking Its Eyeballs

You might notice your Crested gecko licking it’s eyeballs quite often. Usually, this just means they are moisturizing their eyes. Crested geckos do this because they don’t eyelids and use their tongue to moisten their eyes.

What Can Go Wrong

In some cases, excessive licking of their eyeballs, can mean that your Crested gecko is dehydrated. However, this health condition will be accompanied by other symptoms. So, it can’t be diagnosed only from them licking their eyeballs.

Making Noises/Sounds

Crested geckos can make various noises and sounds. This is a normal Crested gecko behavior. The noises they make range from chirping noises to hissing.

Normally, your Crested gecko will make sounds if they are feeling threatened, aggressive/territorial or as a mating call.

What Can Go Wrong

Normally, this is not something to worry about. However, if your Crested gecko is making a hissing noise whilst being handled, it means they are stressed and should be put down.

As long as you listen to your gecko and don’t force them doing something they don’t want, there is nothing to worry about.


As any other animals Crested geckos breed. This usually happens between March and October. They will usually make a squeaky noise when they are about to mate, this is also known as a mating call.

After mating, the male’s hemipenis will stick out. Your gecko will continue licking it until it retracts. This completely normal and nothing to worry about.

What Can Go Wrong

During mating period, both males and females can become more territorial. This means that they might appear aggressive and even try to bite or mate with your hand when you hold them. However, this is nothing to worry about as it’s just their hormones acting out.

The best thing you can do is leave them alone during that time and to not handle them as often if they are displaying any territorial behavior.

Pregnancy And Laying Eggs

Another normal Crested gecko behavior is laying eggs. After your geckos mate, the female will lay eggs, with a new batch of eggs every 3 to 5 weeks and up to 2 eggs in each batch. You need to ensure that your female has a nesting spot in the enclosure. Otherwise, you might see her burying herself in the substrate to create a nesting spot herself.

During the pregnancy and after laying the eggs, you might observe the female Crested gecko acting territorial over her babies. This is normal Crested gecko behavior. However, you should avoid frequent handling during that period.

What Can Go Wrong
  • Too much breeding. On average, if an adult female starts breeding at 12 months of age, she can lay up to 9 clutches per year. However, this is not recommended as it can affect the female’s health. You should allow time to recover between pregnancies
  • Breeding too young. Another thing to avoid is breeding your female before she reaches 12 months of age. Her body wouldn’t have developed yet and it can cause a threat to her health
  • Egg Binding. When a female Crested gecko is pregnant, it’s also known as gravid. In some cases, the eggs are not laid on time and can get stuck in the gravid female’s womb. This condition is also known as egg binding. If you suspect egg binding, you need to take your Crested gecko to the vet as surgery might be required to extract the masses

Changing Color

A normal Crested gecko behavior is changing colors. Crested geckos can change colors depending on their moods and surroundings

When geckos are sleeping, their color gets toned down to a darker tone. This is also known as “fired down”. On the other hand, when the gecko wakes up in the evening, they will “fireup”. This mean their skin tones intensify.

When being “fired up” is the time your gecko will have the richest variation in pigmentation of color.

Leaps Of Faith

Crested geckos originate from dense forests. In their natural environment, they are used to throwing themselves from one branch to another. They usually do this to escape predators. These types of jumps are known as leaps of faith.

When handling your Crested gecko, don’t get alarmed if they try to jump off you and do a leap of faith. That’s completely normal and your gecko even finds it fun.

Abnormal Crested Gecko Behavior

The following Crested gecko behaviors can be a concern in some cases. We’ll be looking at the possible reasons for your Crested gecko displaying this behavior and the possible solutions.

Digging And Burying In The Substrate
