Blue Tongue Skinks are fascinating reptiles that make great pets for reptile enthusiasts. They have unique personalities and striking appearances, which often make people wonder if they can be housed together. In this article, we will explore the characteristics and social behavior of Blue Tongue Skinks, factors to consider before housing them together, how to properly house and care for them, and the types of Blue Tongue Skinks that can live together.

Characteristics of Blue Tongue Skinks

Blue Tongue Skinks, scientifically known as the Tiliqua species, are native to Australia and Indonesia. They are medium-sized lizards, typically reaching lengths of 18 to 24 inches. One of their defining features is their blue tongue, which they use as a defense mechanism to scare away potential predators.

These reptiles have sturdy bodies, short limbs, and a tail that is about two-thirds the length of their body. They come in a variety of colors and patterns, ranging from brown, gray, and black to vibrant oranges and reds. Additionally, Blue Tongue Skinks have smooth scales, giving them a sleek and glossy appearance.

Social Behavior of Blue Tongue Skinks

Blue Tongue Skinks are known to be docile and generally tolerant of human interaction. However, when it comes to socializing with their own kind, their behavior can vary. While some individuals tolerate the presence of other Blue Tongue Skinks, others display territorial behavior and aggression.

Factors to Consider Before Housing Blue Tongue Skinks Together

Before deciding to house Blue Tongue Skinks together, there are several important factors to consider. These factors include the territorial nature of Blue Tongue Skinks, their size and age, and their compatibility with other individuals.

Territorial Nature of Blue Tongue Skinks

Understanding Territorial Behavior

Blue Tongue Skinks, especially males, are naturally territorial creatures. In the wild, they establish and defend their territories, marking them with scent and engaging in territorial displays. This territorial nature is an essential aspect of their survival and mating behaviors.

Territorial Marking

Territorial marking is a crucial behavior for Blue Tongue Skinks, and they use it to communicate with other individuals. They leave scent marks using their cloacal glands or by rubbing their bodies against surfaces. These scent marks act as a way to establish boundaries and let other Blue Tongue Skinks know that the area is already occupied.

Conflict and Aggression

Territorial disputes among Blue Tongue Skinks can lead to conflict and aggression. When two individuals perceive each other as a threat to their territory, they may engage in aggressive behaviors such as hissing, biting, or tail lashing. These confrontations can result in injuries or even death if not properly managed.

Housing Blue Tongue Skinks Together

Space Requirement

When considering housing Blue Tongue Skinks together, it is crucial to provide an adequate amount of space. The enclosure should be spacious enough to allow each skink to have its own territory and to minimize territorial disputes. A general rule of thumb is to allow for at least 40 gallons of space per skink.

Enclosure Setup

The enclosure should be set up to recreate their natural habitat as closely as possible. This means providing a warm basking area, a cooler area for thermoregulation, and a humid hide to help with shedding. Adding enrichment such as branches, rocks, and hiding spots will create a stimulating environment for the skinks.

Temperature and Lighting

Blue Tongue Skinks require specific temperature and lighting conditions to thrive. The basking area should have a temperature range of 90-100°F (32-38°C), while the cooler side should be around 75-85°F (24-29°C). UVB lighting is essential for their overall health and calcium metabolism.


Choosing the right substrate is crucial for the comfort and well-being of the Blue Tongue Skinks. A mix of soil and sand provides a naturalistic environment and allows them to burrow. Avoid using substrates that may cause impaction, such as loose particles or substrates made of small, ingestible materials.

Hiding Spots

Blue Tongue Skinks need hiding spots to feel secure and reduce stress levels. Provide multiple hiding spots throughout the enclosure, such as logs, caves, or half logs, to allow each skink to have their own designated area.

Food and Water

A balanced diet is essential for the health of Blue Tongue Skinks. Their diet should consist of a variety of vegetables, fruits, and protein sources such as insects, snails, and cooked lean meats. Fresh water should be available at all times, provided in a shallow dish that the skinks can easily access.

Cleaning and Maintenance

Regular cleaning and maintenance of the enclosure are necessary to ensure a healthy environment for the Blue Tongue Skinks. Remove any feces, uneaten food, or shed skin to prevent the growth of bacteria and maintain cleanliness. Additionally, disinfect the enclosure regularly to minimize the risk of disease transmission.

Types of Blue Tongue Skinks That Can Live Together

Same Species

Blue Tongue Skinks of the same species can often be housed together successfully, especially if they are raised together from a young age. Individuals of the same species typically have similar social behavior and communication methods, leading to a higher likelihood of compatibility.

Different Species

Housing different species of Blue Tongue Skinks together can be more challenging. It is important to thoroughly research the specific species before attempting to house them together, as some species may have different environmental and social requirements. Always ensure that the size, temperament, and compatibility of the different species are considered.

Mixing Different Ages and Sizes

Adults with Adults

Introducing adult Blue Tongue Skinks to other adults can be risky, as they are more likely to display territorial behavior. If you choose to house adult skinks together, closely monitor their interactions and be prepared to separate them if aggression arises.

Adults with Juveniles

Introducing adult Blue Tongue Skinks to juveniles can also be problematic. Adults may perceive the smaller size of the juveniles as a threat and exhibit aggressive behaviors. It is recommended to house them separately until the juveniles reach a size where they are less vulnerable.

Juveniles with Juveniles

Housing juvenile Blue Tongue Skinks together can be successful, as they are generally more tolerant of their peers. Monitor their interactions closely to ensure that there are no signs of aggression or bullying.

Introducing Blue Tongue Skinks to Each Other

Quarantine Period

Before introducing Blue Tongue Skinks to each other, it is essential to quarantine all individuals for a minimum of 30 days. This period allows you to observe their health, behavior, and any potential signs of illness before introducing them to an established group.

Gradual Introduction

When introducing Blue Tongue Skinks to each other, it is important to do so gradually. Start by placing them in separate enclosures within the same room so that they can become accustomed to each other’s presence and scent. After a period of time, introduce them for short periods under close supervision.

Monitoring and Supervision

Monitor the Blue Tongue Skinks closely during the introduction process. Watch for signs of aggression, stress, or any other behaviors that may indicate compatibility issues. If any signs of stress or aggression are observed, separate the skinks immediately to avoid any injuries.

Signs of Compatibility

Active Exploration

One of the signs of compatibility among Blue Tongue Skinks is active exploration. If the skinks are comfortable in each other’s presence, they will often explore their shared space and interact with each other in non-aggressive ways.

Sharing Hiding Spots

Another positive sign of compatibility is sharing hiding spots. If the Blue Tongue Skinks feel secure in each other’s presence, they may use the same hiding spots or even share a hide to rest together.

Peaceful Coexistence

Peaceful coexistence is the ultimate goal when housing Blue Tongue Skinks together. If the skinks are able to live together without any signs of aggression or stress, it is a positive indication that they are compatible.

Signs of Incompatibility


Aggression is a clear sign of incompatibility among Blue Tongue Skinks. If one skink consistently displays aggressive behavior towards another, such as biting or tail lashing, it is important to separate them to prevent injuries.

Bullying or Dominance

Bullying or dominance behaviors, such as constantly chasing or harassing another skink, indicate an imbalance in the social dynamics. If one skink is consistently dominating or bullying another, it is necessary to provide them with separate accommodations.

Stress and Anxiety

Stress and anxiety can manifest in various ways, such as loss of appetite, hiding excessively, or excessive pacing. If a skink consistently displays signs of stress or anxiety in the presence of another skink, it may be better to house them separately.


Injuries resulting from aggressive interactions are a clear indication of incompatibility. If any skink shows signs of physical harm, immediate separation is necessary to prevent further harm and for the injured skink to receive proper care.

Separating Blue Tongue Skinks

Recognizing Issues

Recognizing when Blue Tongue Skinks need to be separated is crucial to prevent further harm. Pay close attention to their interactions and behaviors, and if any signs of aggression, stress, or injury are observed, take immediate action to separate them.

Providing Individual Space

When separating Blue Tongue Skinks, it is important to provide each individual with its own separate enclosure. This will allow them to establish their territory and reduce the stress caused by communal living.

Behavioral Intervention

In some cases, behavioral intervention may be necessary to address issues of aggression or stress. Consulting with a reptile veterinarian or an experienced reptile behaviorist can provide assistance in assessing the situation and developing a behavioral intervention plan if needed.


While it is possible for Blue Tongue Skinks to live together, it is crucial to consider their individual personalities, temperaments, and their specific social and environmental requirements. Careful preparation, monitoring, and ongoing evaluation are necessary to ensure the well-being and compatibility of the Blue Tongue Skinks. Remember that every skink is unique, and not all skinks will thrive in a communal environment. Always prioritize the health and safety of these remarkable reptiles and provide them with a suitable and stress-free living situation.
