Understanding Tarantulas

Tarantulas are a diverse and captivating group of spiders, known for their large size, hairy bodies, and unique behaviors. They belong to the family Theraphosidae and can be found in various habitats around the world, from tropical rainforests to arid deserts.

Types of Tarantulas

There are many species of tarantulas, each with their own distinct characteristics and needs.

Genus Common Species Geographic Location
Aphonopelma Chalcodes, Anax United States, Mexico
Brachypelma Smithi (Mexican Red-Knee) Mexico
Grammostola Pulchra (Brazilian Black) South America
Poecilotheria Regalis (Indian Ornamental) India, Sri Lanka
Avicularia Avicularia (Pinktoe) South America

The Concept of Communal Setup

Before delving into the breeding aspect, it’s important to understand what a communal setup entails. Essentially, a communal setup involves housing multiple tarantulas together in the same enclosure. This setup can provide some benefits but also poses significant challenges.

Benefits and Challenges

Communal setups can be advantageous in terms of space-saving and creating more naturalistic environments. However, they also bring about challenges related to the natural solitary and territorial behavior of tarantulas.


  1. Space Efficiency: Combining multiple tarantulas in one enclosure can save space and simplify management.
  2. Naturalistic Behaviors: In certain species, communal setups can encourage behaviors seen in the wild.
  3. Observation Opportunities: Watching interactions between individuals can be fascinating and educational.


  1. Aggression and Cannibalism: Many tarantulas are solitary and may display aggression or cannibalistic behavior towards each other.
  2. Feeding Issues: Ensuring every individual gets enough food can be tricky.
  3. Disease and Parasites: Communal living can facilitate the spread of diseases and parasites.

Species Suitable for Communal Setups

Not all tarantulas are candidates for communal living. Certain species are more tolerant of living in close quarters with others of their kind.

Recommended Species

While many tarantulas are strict loners, a few species have been reported to do relatively well in communal setups:

Genus Species Notes on Communal Behavior
Poecilotheria Metallica, Regalis Known for some success in community settings
Avicularia Avicularia, Versicolor Can sometimes be kept communally in large spaces
Monocentropus Balfouri Frequently cited as being more communal
Holothele Incei Often raised communally by hobbyists

Species to Avoid

Similarly, some species are highly territorial and should be avoided in communal setups:

Genus Species Notes on Territorial Behavior
Grammostola All species Known for being particularly solitary and territorial
Brachypelma All species High tendency for aggression towards tank mates
Theraphosa Blondii (Goliath Birdeater) Large size and aggression make communal setups impractical

Preparing a Communal Setup

Creating a successful communal setup involves careful planning and attention to detail. Here is a breakdown of what you need to consider.

Enclosure Size and Environment

A communal setup requires a larger-than-normal enclosure to prevent conflict and provide enough resources for all inhabitants.

  1. Size: The enclosure should be spacious enough to allow each tarantula to establish its own territory.
  2. Hiding Spots: Provide multiple hiding spots and shelters to reduce stress and territorial disputes.
  3. Humidity and Temperature: Match the species’ natural habitat requirements, ensuring a stable microenvironment.

Feeding and Nutrition

Feeding multiple tarantulas in one enclosure can be a logistical challenge.

  1. Feeding Strategy: Implement a strategy that ensures all individuals have access to food. This may involve hand-feeding or using multiple feeding stations.
  2. Monitor Intake: Regularly check that all tarantulas are eating properly, as stronger individuals might monopolize food sources.

Health Monitoring

Keeping tarantulas healthy in a communal setup requires vigilance.

  1. Regular Checks: Conduct frequent health checks to identify signs of stress, disease, or injuries.
  2. Isolation Protocols: Have a plan in place to isolate injured or stressed individuals if needed.

The Breeding Process

Breeding tarantulas in a communal setup is intricate and requires understanding their reproductive behaviors.

Mating Rituals

Tarantula mating involves complex rituals that are fascinating to observe but can also be risky.

  1. Male Introduction: Introduce males to the communal enclosure carefully. Males in search of mates may face aggression from both females and other males.
  2. Courtship: Males perform courtship dances and drumming to signal their intentions to females.

Post-Mating Care

After mating, females may require special care.

  1. Egg Sac Production: Provide a stable environment for females to produce and care for egg sacs.
  2. Hatchlings: Once the eggs hatch, young spiderlings will need proper care and feeding.

Potential Pitfalls

Breeding in communal setups can lead to several complications.

  1. Cannibalism Risk: Males are often at risk of being cannibalized by females after mating.
  2. Overcrowding: A successful breeding can quickly lead to overcrowding, necessitating expansion or individual rehousing of spiderlings.

Case Studies and Real-World Examples

Looking at real-world examples can provide valuable insights into the feasibility of breeding tarantulas communally.

Monocentropus Balfouri

This species is frequently cited in communal breeding success stories.

  1. Case Study: Several hobbyists have reported success breeding Monocentropus Balfouri in communal setups without significant aggression.
  2. Method: These setups often include a large enclosure with plenty of hiding spots and a stable environment.

Avicularia Species

Success with Avicularia species varies but offers an interesting glimpse into potential communal breeding.

  1. Case Study: Some breeders have managed to raise Avicularia spiderlings communally, though with careful monitoring.
  2. Method: Emphasizing vertical space and plenty of foliage can mimic their natural arboreal habitat.

Ethical Considerations

Breeding tarantulas in a communal setup raises important ethical questions.

Welfare of the Tarantulas

Ensuring the well-being of each individual is paramount.

  1. Stress Levels: Monitor closely for signs of stress which can lead to health problems.
  2. Aggression Management: Intervening when aggression occurs is essential to prevent harm.

Conservation Implications

Responsible breeding can contribute to conservation efforts.

  1. Captive Breeding: Successfully breeding tarantulas in captivity can reduce the demand for wild-caught specimens.
  2. Education and Awareness: Breeding programs can help raise awareness and appreciation for these fascinating creatures.

Best Practices for Success

Implementing best practices can increase the likelihood of successful communal breeding.

Research and Planning

Knowledge is key to a successful communal setup.

  1. Species-Specific Research: Understand the specific needs and behaviors of the species you intend to breed.
  2. Setup Design: Design your communal enclosure with ample space, hiding spots, and environmental stability.

Patience and Vigilance

Breeding tarantulas communally is not a process that can be rushed.

  1. Monitoring: Regularly observe and note any changes in behavior, health, or environment.
  2. Adjustment: Be prepared to make adjustments to the setup as needed to ensure the well-being of all tarantulas.
