Understanding Bearded Dragons and Tarantulas
Before delving into enclosure ideas, it’s crucial to understand the distinct needs of both bearded dragons and tarantulas. These fascinating creatures, though both popular pets, have vastly different requirements in terms of habitat, diet, and behavior. This knowledge is paramount when considering cohabitation. Bearded dragons, native to the arid and semi-arid regions of Australia, thrive in warm, dry environments, needing UVB and heat lamps for health and well-being. Tarantulas, on the other hand, come from diverse habitats worldwide, with varying preferences depending on the species, but generally require more humidity and a substrate conducive to burrowing or web-spinning. This fundamental understanding is key to ensuring the health and happiness of any pet, especially when considering housing different species together.
Bearded Dragon Habitats Overview
Bearded dragons need spacious enclosures, preferably at least 4 feet long, 2 feet wide, and 2 feet high for adults. The enclosure should be well-ventilated and equipped with a basking spot that reaches 95-110°F (35-43°C) and a cooler side for thermoregulation. UVB lighting is essential for vitamin D3 synthesis and overall health, and the substrate should be reptile-safe, like tile, paper towels, or a bioactive substrate. Decorations should include basking rocks, branches for climbing, and hides for security. Regular cleaning and spot checks are a must, with the substrate changed as needed to maintain hygiene. Proper care ensures they can thrive in their environment.
Tarantula Habitats Overview

Tarantula enclosures vary significantly based on species, with humidity and substrate being key factors. Terrestrial tarantulas often need a substrate of coco fiber, peat moss, or a mixture thereof, kept slightly moist. Arboreal tarantulas require more vertical space and may benefit from cork bark or branches for climbing and webbing. Ventilation is important to prevent mold growth, but excessive airflow can dry out the enclosure. They should have a water dish and a hide, ensuring a safe, secure environment. Depending on species, the enclosure size will vary; however, providing the right setup will ensure their safety and well-being.
Why Consider a Combined Enclosure
Cohabitation, while potentially risky, offers unique opportunities for reptile enthusiasts looking to create visually stimulating and space-saving enclosures. A well-designed combined enclosure can offer both species a stimulating environment, with carefully chosen elements that cater to their distinct requirements. However, it’s vital to approach this concept with caution, prioritizing the welfare and well-being of both animals. By carefully considering the environmental needs of both species, and by acknowledging the potential challenges, it is possible to create a harmonious environment.
Benefits of Co-habitation
A well-executed combined enclosure can maximize space and offers a unique viewing experience. For reptile keepers with limited space, combining enclosures can be practical. Additionally, a carefully designed setup can introduce variety to the environment, promoting natural behaviors in both species. However, this setup is not recommended if you’re a beginner, or have limited experience handling and monitoring reptiles, it’s best to avoid cohabitation for the sake of their health and safety.
Potential Risks and Challenges

The risks of cohabitation include competition for resources, stress, and even predation. Bearded dragons, being larger and more active, could potentially harass or even injure a tarantula, while some tarantula species have venom. Furthermore, maintaining the vastly different environmental conditions required by both species is a complex task, which can easily lead to health problems. Careful planning, species selection, and constant monitoring are essential to mitigate these risks and ensure that both animals can thrive in their shared habitat. The best option is to house each reptile on its own, so you can better control the environment.
Top 5 Tarantula Enclosure Ideas
Idea 1 The Desert Oasis
The Desert Oasis enclosure style mimics the natural environment of a bearded dragon while incorporating a tarantula-friendly zone. It’s important to separate the enclosure with a partition or barrier to avoid direct contact between the two species. This setup works best for terrestrial tarantula species. The bearded dragon side replicates a desert habitat, with a basking spot, UVB lighting, and a substrate suitable for the dragon. The tarantula’s section contains moist substrate, a hide, and a water dish.
Key Features and Design

Use a large enclosure with a secure divider. Ensure the bearded dragon’s area has proper heating and UVB. In the tarantula’s section, provide a deeper substrate and a hide. The enclosure should have multiple access points for easy feeding and cleaning. Decorations can include artificial rocks, plants, and other natural elements to create a visually appealing and functional habitat. Maintaining the proper humidity and temperature gradients is vital for both animals.
Idea 2 The Bioactive Setup
A bioactive enclosure utilizes a living ecosystem to maintain itself, reducing the need for frequent cleaning. This is especially appealing when housing multiple species. For a combined bioactive enclosure, the bearded dragon’s section would be designed with a substrate of soil, sand, and leaf litter, supporting the growth of beneficial bacteria and invertebrates. The tarantula’s area would have a similar setup, with a focus on maintaining the proper humidity levels needed for their health and well-being. Both sides should include hardy plants that can survive the conditions in their habitat.
Benefits of a Bioactive Enclosure
Bioactive enclosures naturally manage waste and provide a more stable environment. The presence of isopods, springtails, and other beneficial organisms helps break down waste and aerate the substrate. This reduces the need for frequent substrate changes and contributes to a cleaner, healthier habitat. The plants and other organisms work together to create a natural, balanced ecosystem, providing enrichment and promoting the well-being of the pets. It is important that the setup is carefully planned to meet the specific needs of both species.
Idea 3 The Vertical Terrarium

A vertical terrarium setup is ideal for arboreal tarantulas. This design is about maximizing the space, with the tarantula’s habitat being more vertically oriented, offering ample climbing space. The bearded dragon’s area could be designed with a focus on basking and climbing, with appropriate UVB lighting and heating. While this layout might be more challenging, it presents an appealing option, if the species are chosen thoughtfully.
Design and Considerations
The design should have a secure barrier to separate the species. The tarantula’s section needs climbing surfaces and a hide, while the dragon needs a basking spot and UVB access. Ensure proper ventilation and temperature control throughout the enclosure. Carefully select the plants and decorations to provide visual interest and enrichment. Make sure you monitor the behavior of both animals closely to see if they are getting along in their habitat.
Idea 4 The Divided Enclosure
The divided enclosure is the most straightforward and safest method, involving a physical barrier separating the two species within a shared enclosure. The key is to ensure the barrier is secure, non-toxic, and does not allow either animal to cross or have any physical contact. This setup maintains the separate environmental needs of each species.
Setting up a Divided Environment

Choose a large enclosure, then install a solid, secure divider, and the material must be non-toxic and appropriate for both species. The bearded dragon side should have its own heating and UVB lighting, while the tarantula side should have the right humidity, substrate, and a hide. Be sure to keep the setup clean and monitor both sides regularly. This will allow both species to thrive without interference.
Idea 5 The Dual-Level Habitat
A dual-level habitat offers a unique approach by housing one species above the other, maximizing vertical space and minimizing direct interaction. This is more suitable for terrestrial tarantulas and bearded dragons. The bearded dragon has access to the ground level, with the tarantula’s enclosure above. This design allows for natural behaviors and is well-suited for those who love to observe their pets.
Creating a Dual-Level Environment
The design includes a sturdy frame that can support the weight of both enclosures. The upper level houses the tarantula, and the lower level houses the bearded dragon. Make sure both the lower and upper enclosures have all their needs met for their own well-being. The tarantula’s enclosure should be sealed, and access to the upper enclosure should be secure to prevent escape. Make sure the entire setup provides adequate ventilation, temperature, and humidity control.
Essential Enclosure Accessories

Temperature and Humidity Control
Consistent temperature and humidity levels are vital for the health of both species. Provide a temperature gradient in the bearded dragon’s area, with a basking spot and cooler zones.
