Understanding the Vietnam Blue Tarantula
The Vietnam Blue Tarantula (Chilobrachys dyscolus) is a captivating and increasingly popular pet within the tarantula-keeping community. Known for its striking blue coloration, this species hails from the tropical forests of Vietnam, where it thrives in a humid environment. Understanding the needs of this spider is crucial for its well-being. This guide provides a comprehensive overview of everything you need to know to successfully care for a Vietnam Blue Tarantula, ensuring a healthy and fulfilling life for your pet. This species is known for its relatively docile temperament compared to other tarantulas, making them a good choice for intermediate keepers. However, all tarantulas deserve respect, and proper care and handling are essential.
Origin and Habitat
Native to the tropical regions of Vietnam, these tarantulas are adapted to a warm and humid environment. They are typically found in burrows or under cover in the forest floor. The natural habitat influences their care requirements. Replicating these conditions in captivity is key to their health and longevity. Understanding their origin helps in creating an appropriate and enriching environment, which can significantly reduce stress. The importance of mimicking their natural environment cannot be overstated; it’s crucial for their physical and psychological health.
Appearance and Characteristics

The Vietnam Blue Tarantula’s most distinguishing feature is its stunning blue coloration, which intensifies as they mature. They are medium-sized tarantulas, with females typically reaching a leg span of around 5-6 inches. They have a moderate growth rate. Males are typically smaller than females and may display different coloration. These spiders possess a moderate urticating hair defense mechanism. They are known to be terrestrial, meaning they spend most of their time on the ground.
Setting Up the Perfect Habitat
Creating a suitable habitat is the cornerstone of successful Vietnam Blue Tarantula care. The enclosure should provide adequate space, appropriate substrate, and the right environmental conditions. Attention to detail in this setup phase will pay dividends in the long run, ensuring the spider’s comfort and well-being. A well-designed habitat will not only meet the spider’s basic needs but also allow you to observe its fascinating behaviors.
Enclosure Size and Type
A terrestrial enclosure is essential. A general rule is that the enclosure should be at least twice the tarantula’s leg span in width and length, and the height should be at least equal to the leg span. A secure lid is crucial to prevent escape. Glass or acrylic enclosures are both suitable options. Good ventilation is critical to prevent the buildup of humidity and mold.
Substrate Selection

The substrate should retain humidity without becoming waterlogged. A mixture of peat moss, coconut fiber, and a small amount of vermiculite is ideal. The substrate should be deep enough (3-5 inches) for the tarantula to burrow if it chooses. Avoid substrates with sharp edges. Regular spot cleaning is essential to maintain hygiene.
Decorating the Habitat
Include a hide, such as a piece of cork bark or a pre-made hide, for the tarantula to retreat to. Provide a shallow water dish for drinking. You can also add artificial plants or decorations. However, make sure the enclosure is not overcrowded, leaving ample space for the tarantula to move around. Regularly check the decorations and remove any mold or food debris.
Temperature and Humidity
Maintain a temperature between 75-85°F (24-29°C). Use a heat source, such as a heat mat attached to the side of the enclosure, if necessary. Humidity levels should be kept around 60-70%. Monitor the humidity with a hygrometer. Mist the enclosure lightly with water once or twice a week. Avoid excessive condensation.
Feeding Your Vietnam Blue Tarantula

Providing a proper diet is critical for your tarantula’s health and growth. The right food sources, feeding schedule, and access to water will ensure your spider lives a long and healthy life. It’s important to observe your tarantula’s feeding behavior and adjust the schedule as needed, depending on its stage of growth.
Diet and Feeding Schedule
Feed your tarantula appropriately sized insects. Crickets, mealworms, and roaches are suitable choices. The size of the prey should be no larger than the tarantula’s abdomen. Feed spiderlings 2-3 times a week, juveniles once or twice a week, and adults every 1-2 weeks. Remove any uneaten prey within 24 hours to prevent stress and potential harm to your tarantula.
Water and Hydration
Provide a shallow water dish filled with fresh water. Ensure the water dish is easily accessible and not too deep to prevent the spider from drowning. Check the water level regularly and refill as needed. You can also lightly mist the enclosure to provide additional moisture and encourage drinking. Always use dechlorinated water.
Handling and Safety

While the Vietnam Blue Tarantula is known for being relatively docile, it is important to exercise caution when handling your pet. Understanding the correct handling guidelines and potential hazards associated with tarantulas is crucial for your safety and the spider’s well-being. It’s important to remember that all tarantulas possess defense mechanisms, and respecting these is a sign of responsible pet ownership.
Handling Guidelines
Handling should be kept to a minimum, and only when necessary. Always handle your tarantula close to the ground or a soft surface. Never drop your tarantula, as this can be fatal. Use a soft brush to gently guide the spider if needed. Wash your hands thoroughly before and after handling.
Identifying Potential Hazards
Be aware of the tarantula’s defensive behaviors, such as raising its front legs or flicking urticating hairs. Avoid sudden movements and loud noises. Be cautious of the fangs. A bite from a Vietnam Blue Tarantula is not generally considered medically significant, but can be painful. Always supervise children around tarantulas and teach them the importance of respecting these animals.
Health and Common Issues

Like all pets, Vietnam Blue Tarantulas can experience health issues. Knowing how to recognize molting, as well as common health problems, is vital for ensuring a long and healthy life for your tarantula. Prevention through proper care is always the best medicine.
Recognizing Molting
Molting is the process where the tarantula sheds its exoskeleton. During this time, the tarantula may become inactive, lose its appetite, and lie on its back. Do not disturb your tarantula during molting. Provide ample humidity, and avoid feeding until the new exoskeleton has hardened. The process can take anywhere from a few hours to several days depending on the spider’s size and the environmental conditions.
Common Health Problems
Dehydration can occur if humidity is too low. Ensure adequate water and misting. Mites can infest tarantulas; quarantine and treat affected individuals. Fungal infections can develop in overly humid environments; ensure good ventilation. If you notice any unusual behavior or signs of illness, consult with a veterinarian experienced with exotic pets.
Lifespan and Breeding

Understanding the lifespan and breeding habits of your Vietnam Blue Tarantula can help you prepare for the future and gain a deeper appreciation for the species. While breeding is more complex, knowing the basics will add to your understanding.
Average Lifespan
Female Vietnam Blue Tarantulas can live for 10-15 years, sometimes longer. Males typically have a shorter lifespan, living for 3-5 years after reaching maturity. Proper care and environment contribute to a longer lifespan.
Breeding Considerations
Breeding Vietnam Blue Tarantulas in captivity can be challenging and requires specialized knowledge and setup. Ensure the female is well-fed before introducing her to a male. Be prepared to separate the male after mating to prevent the female from attacking him. Provide a suitable egg sac, and raise the spiderlings in a separate environment, offering appropriate feeding and care. Breeding is not recommended for beginners.
