Do Geckos Eat Each Other

Geckos are fascinating creatures that have become increasingly popular as pets in recent years. They are known for their unique ability to climb walls and ceilings, and their distinctive chirping sounds. However, one question that many people have about geckos is whether or not they eat each other.

The answer to this question is not a simple yes or no. While geckos are generally not cannibalistic, there are some circumstances in which they may eat each other. For example, sick or injured geckos may be more likely to be seen as prey by their healthy counterparts. Additionally, overcrowding or a lack of food can also lead to geckos turning on each other.

Geckos can eat each other for a variety of reasons. One of the most common reasons is due to competition for resources, such as food and territory. When geckos are kept in captivity, they may become territorial and aggressive towards each other, leading to cannibalism. Some species of geckos are also known to eat their own offspring, which may be a way to eliminate competition for resources and ensure the survival of the strongest individuals.

It is important for gecko owners to be aware of the potential for cannibalism and to take steps to prevent it. This can include providing adequate space, food, and hiding places for all geckos in the enclosure.

Do Geckos Eat Each Other?

Geckos are known to be carnivorous, and they will eat almost anything that they can catch, including insects, spiders, and other small animals. However, when it comes to eating each other, the answer is not so straightforward.

There are two main types of cannibalistic behavior observed in geckos: intra-specific and inter-specific. Intra-specific cannibalism refers to geckos eating members of their own species, while inter-specific cannibalism refers to geckos eating members of other species.

Intra-specific cannibalism is the most common type of cannibalistic behavior observed in geckos. It usually occurs when resources are scarce or when geckos are housed in overcrowded conditions.

Inter-specific cannibalism is less common, but it has been observed in some species of geckos. It usually occurs when geckos are introduced to each other’s territories or when they are housed together without proper supervision.

Cannibalism varies depending on the species of gecko. For example, Leopard Geckos are known to have a significant predatory response to small moving things, and they are known to eat smaller members of other species. However, in other species, cannibalism is not common.

It is important to note that geckos are territorial animals, and they will defend their territory from other geckos. In some cases, this can lead to fighting, and if one gecko is injured or weak, it may become prey for the stronger gecko.

Overall, while geckos are not known for eating each other, it is not uncommon for them to do so in certain circumstances.

It is important to provide geckos with enough space and resources to avoid territorial disputes and potential cannibalism.

Reasons Why Geckos Eat Each Other

Geckos are known to eat other geckos, but this is not a common occurrence. There are several reasons why geckos may eat each other, including:

Territorial disputes

Geckos are territorial creatures and will defend their space from other geckos. If two geckos are placed in the same enclosure and they perceive each other as a threat, they may engage in a fight that can result in one gecko eating the other.

Mating competition:

Male geckos can become aggressive towards each other when competing for a female mate. This aggression can lead to fights and, in some cases, one gecko may end up eating the other.

Food scarcity:

In the wild, geckos may struggle to find enough food to sustain themselves. If a gecko is hungry enough, it may turn to cannibalism and eat other geckos to survive.

Weak or sick geckos:

Geckos are opportunistic feeders and will eat anything they can catch, including weak or sick geckos. If a gecko is injured or sick, it may become an easy target for other geckos looking for a meal.

Aggressive Behavior

Finally, geckos may eat each other simply because they are aggressive animals. Some geckos are naturally more aggressive than others, and they may attack and eat other geckos without any provocation.

Size Difference

Another reason for cannibalism is size difference. Larger geckos may see smaller geckos as prey, especially if they are hungry or if they perceive the smaller geckos as a threat to their territory.

Maturity and hierarchy can also play a role in cannibalism. Dominant geckos may prey on weaker or subordinate geckos as a way of asserting their dominance.

It is important to note that geckos do not typically eat each other as a regular part of their diet.

Cannibalism is a rare occurrence that usually only happens under certain circumstances.

Owners of pet geckos can help prevent cannibalism by providing each gecko with its own enclosure and ensuring that they have enough space and resources to live comfortably. It is also important to monitor geckos for signs of illness or injury and separate them from other geckos if necessary.

How to Prevent Geckos from Eating Each Other

Geckos are known to eat each other, especially when they are housed together in small enclosures or when they are not well-fed. To prevent this from happening, there are several steps that you can take to ensure that your geckos are happy and healthy.

Habitat Considerations

One of the most important things to consider when preventing geckos from eating each other is their habitat. It is important to provide them with enough space to move around and establish their own territories. Overcrowding can lead to stress, which can cause geckos to become aggressive towards each other.

Make sure that the enclosure is large enough to accommodate all of your geckos comfortably. Provide hiding places and climbing structures to give them a sense of security and privacy. This will help to reduce stress and prevent aggressive behavior.

Feeding and Nutrition

Another important factor to consider is the feeding and nutrition of your geckos. Make sure that they are well-fed and have access to fresh water at all times. Geckos that are hungry or dehydrated are more likely to become aggressive towards each other.

Provide a varied diet that includes a mix of insects, such as crickets, mealworms, and waxworms. You can also supplement their diet with fresh fruits and vegetables. Make sure that the insects are gut-loaded before feeding them to your geckos to ensure that they are getting the proper nutrition.


Geckos are social creatures, but they can also be territorial. It is important to introduce new geckos slowly and carefully to prevent aggression. When introducing new geckos, keep them in separate enclosures for a few weeks to allow them to get used to each other’s scent.

After a few weeks, you can start to introduce them to each other by placing them in a neutral territory, such as a clean enclosure. Keep a close eye on them and watch for any signs of aggression, such as biting or tail whipping. If they seem to be getting along, you can gradually increase the amount of time that they spend together.

Overall, preventing geckos from eating each other requires careful consideration of their habitat, feeding and nutrition, and socialization. By taking these steps, you can help to ensure that your geckos are happy, healthy, and safe.

Frequency of Cannibalism

The frequency of cannibalism in geckos varies depending on the species and the environment. In some species, cannibalism is a rare occurrence, while in others it is more common.

Studies have shown that cannibalism is more likely to occur in geckos that are housed in overcrowded conditions or that are kept in captivity without proper care and supervision. It is important for gecko owners to provide their pets with adequate space, food, and resources to prevent cannibalistic behavior.


Geckos are fascinating creatures that have unique behaviors and diets. While geckos are not strictly carnivorous, they are known to eat small insects, lizards, and even other geckos. Cannibalism varies depending on the species, and it usually occurs when geckos are young.

As they get older, their diet consists mostly of insects. Geckos possess a short, stout body, a large head, and typically well-developed limbs.

The ends of each limb are often equipped with digits possessing adhesive pads. Most of the species are 3 to 15 cm (1.2 to 5.9 inches) long, and they are mostly small, usually nocturnal reptiles with a soft skin. Perhaps one of the oddest facts about geckos is that most species lack eyelids. Because they cannot blink, they lick their eyes to keep them clean and moist.

(Well, technically, they’re licking their eyeballs, which are covered by a transparent membrane called the “spectacle.”) Gecko mating behavior is also unique.

Male geckos will often fight with each other for the opportunity to mate with a female. The winner of the fight will then mate with the female.

Female geckos can lay up to 2 eggs at a time! In conclusion, geckos are fascinating creatures with unique behaviors and diets. While they are known to eat other geckos, it usually only occurs when they are young. As they get older, their diet consists mostly of insects. Their lack of eyelids and unique mating behavior make them even more intriguing.
