Although the docile, “smiling” leopard geckos may seem to be cool about everything and anything, they can get stressed as well. Prolonged stress is unhealthy and can seriously degrade your leo’s wellbeing.

Fortunately, although they really can’t warn us about what is going on, the stress in leopard geckos is usually visible, solvable, and preventable.

Let’s see what might stress your dear pet leopard gecko, and what can you do about it.

Is My Leopard Gecko Stressed? What Are the Signs and the Causes?

Here is the list of most common stress signs in captive leopard geckos:

  1. Stress Licking
  2. Stress Waving
  3. Vocalizing
  4. Excessive Hiding
  5. Closed Eyed
  6. Glass Surfing
  7. Cohabitation Stress

Stress Licking

Leopard geckos use their tongues to sniff out their environment. They will readily do it when they are in the exploration mode. You can observe this behavior when you take your leo out of the tank – he will be diligently soaking in the smells of his environment with the help of that cute stubby tongue.

However, if you notice your gecko is doing the licking too much, it can be a sign of a severe issue. Mouth rot is a serious condition that is often accompanied by excessive licking, as well as by some or all of the following symptoms:

  • Gaping mouth.
  • Lack of appetite.
  • Mucus, or puss around the mouth.
  • Willing to eat, but unable to pick up food.

In many cases, mouth rot is precluded by a drop in immunity caused by long-term stress.

The condition has to be treated by a reptile vet immediately. After a, hopefully, successful healing, you should completely review your gecko’s everyday living conditions.

Eye Licking is a separate issue. Leos will normally lick their eyes to keep them clean and moist. However, if you notice your pet is licking them too much, it can signal a stuck shed, something else stuck in the eye that they can’t get rid of.

Stress Waving

Leopard geckos will sometimes wave or shake their tails in favorable circumstances – like when stalking prey, or when courting a female.

However, most of the time, waving the tail simply means “Stay away. Don’t touch me.” Leos will usually wave in an attempt to fend off a threat – a competitor, a predator, or any creature they feel threatened by.

If your leopard gecko is young and brought to your home just recently, tail waving will be a normal reaction before you try to handle him. He is trying to ward you off, but if you’re patient and not pushy, he will soon learn that you are not a threat. But try to leave him alone as soon as he shows these signs and take it one step at the time.


When bothered, a leopard gecko will produce a squeaking, chirping, or a quacking sound. Vocalization has the same function as tail waving, so you should do the same – when you hear him squeak while being handled, loosen up your grip or put him back in the tank.

Excessive Hiding

Excessive hiding can mean various things.

In the case you got your leopard gecko only recently, hiding is pretty normal behavior. He needs some time to adapt. As long as he is not on a hunger strike, let him hide for up to several weeks.

However, excessive hiding beyond this period could be a sign that something is wrong with either your leo’s environment or his health. Check for these issues:

  • Is your leo too cold? Geckos in cold tanks with no heat spot will often hide to conserve energy.
  • Is your gecko too hot? If your leo is always hiding in the cool part of the tank, check the general temperature, as well as the temperature at his basking spot under a heat lamp.
  • Do leo’s limbs and spine look normal? Lethargy and difficulty moving are common features of Metabolic Bone Disease (MBD), a dangerous condition that occurs because of a lack of calcium and vitamin D3.

Closed Eyes

If the gecko is sluggish and keeps his eyes closed often, first check if the temperatures are too low.

Eyes that are closed too often in an otherwise healthy gecko can also signal that the lights in his tank are too bright, and/or that he doesn’t have a hide he likes.

If you have determined that nothing is wrong with his environment, you must know that closed eyes and lethargy can also signal several problems – an illness such as the aforementioned MBD, parasites, and many other alignments. Also, a leo will close his eyes if he is in pain.

Glass Surfing

Glass surfing or glass dancing is a sign that a gecko is distressed and wants to escape the uncomfortable situation. Cohabitation stress, mites in the tank, too much heat, a tank that is too small or even too dull can all trigger glass surfing.

Sometimes a glass surfing event will appear from no obvious reason and will simply pass. If the mysterious dancing sessions are re-occurring, then you should pay much closer attention to the possible triggers.

Cohabitation Stress

Leos are solitary animals. They don’t need each other’s company. However, two or more females can tolerate each other, which has made the cohabitation popular.

However, incidents are sure to occur, especially during feeding time. Most leos are agile and aggressive hunters. When they turn this aggression onto each other during feeding time, things can get nasty really quickly.

In general, we don’t recommend cohabitation.

Can Fans Stress out a Leopard Gecko?

Sometimes, fans are used in terrariums to increase air circulation. They are more common in moist, rainforest setups than in dry, desert-type tanks suitable for geckos.

However, if you live in a home with high humidity levels, a fan may do wonders for preventing the humidity buildup inside the tank.

If positioned right, a small, PC-type fan will not stress out your leos. Preferably, it should be attached to the back wall high up in the tank near the ventilation, so the air will circulate under the ceiling and not on the ground where the lizard is.

The air should never blow at or over your leopard geckos!

Does UVB Light Stress Leopard Gecko?

UVB light belongs to the invisible part of the light spectrum. Therefore, UVB itself can’t stress leopard geckos. It might happen with a full-spectrum light that includes UVB, but it’s not UVB’s fault.

On the other hand, the gecko’s stress will surely reach its peak if he gets a metabolic bone disease from the lack of vitamin D3, the essential thing that the UVB bulb helps him get.

Although UVB lights have been forsaken in the leo enthusiast world for decades, recent experience supports its use. So don’t fear it. Just make sure you get the levels right – 5-6% T8 or T5 tube (2% for albino morphs) will provide sufficient UVB for leopard geckos.

Can Crickets Stress a Leopard Gecko?

As mentioned earlier, crickets can be a great snack, but a terrible cohabitant in the terrarium. They can bite and even stalk your pet leo and cause him quite a lot of aggravation.

Always make sure that all the crickets in the tank are eaten when you are feeding them. Don’t let a single one remain in the tank.

Can Leopard Geckos Die Of Stress?

Geckos won’t die from the stress itself, but rather from the underlying causes of stress – such as disease or mismanagement.

That is why it is very important to pinpoint the causes of strange stress-related behavior, so you can address the causes ASAP before serious damage is done.

Do Leopard Geckos Like to Be Held?

Leopard geckos do not have a need to be held and cuddled as your dog has.

However, most leos are tolerant of being handled, and some even like it (in reasonable quantities). The attitude will also depend on your gecko’s personality and previous experiences when being handled.

What my leos love the most about handling is the warmth of human hands. Remember that our palms radiate heat, which goes normally reaches 37 degrees Celsius. Almost like a heat rock!

If you plan to hold your leo often, tame him at a young age.

  • Doing a lot of research from reputable sources before picking your pet and bringing it home (find out more in our Leopard Gecko guides).
  • Arranging his terrarium in line with the best-recommended practices is absolutely the best way to avoid stress in leopard geckos. Note that pet stores are usually not the best places to get your information from.
  • Finding a healthy individual with good genetics is also ensures that the animal will not suffer stress from being improperly kept in the trade. Getting your pet from a reputable leopard gecko breeder is usually enough to ensure that your future pet will start his new life in good shape.
  • Do not handle your leos too much. Stop when you see that your leo is getting restless and nervous and put him back into his tank. When you do handle them, do it without squeezing or pulling. Allow natural movement, but control it at all times.
  • And last but not least, feeding your gecko the right food with just enough supplements, and paying close attention to safety when feeding them feisty feeders such as crickets and superworms will also do wonders for your gecko’s stress-free life.

Take Care!

Stress is a common occurrence in all living creatures, but the most important thing is to recognize it and address it in time. With a little bit of reading and experience, the signs of stress are easy to spot, and, in most cases, the issues are easy to resolve.
