What is a Gooty Sapphire Tarantula (GST)
The Gooty Sapphire Tarantula (Chilobrachys natans), often abbreviated as GST, is a captivating and highly sought-after species within the tarantula hobby. Native to India, these spiders are renowned for their striking appearance and fascinating behaviors. Their beauty is undeniable, with metallic blue or sapphire hues adorning their legs and carapace, contrasted against a dark body. This vivid coloration, combined with their relatively manageable size, has made them a favorite among both novice and experienced tarantula keepers. Understanding the GST is the first step towards providing the appropriate care and ensuring their well-being in captivity, which this guide aims to cover.
Appearance and Characteristics
The Gooty Sapphire Tarantula boasts a unique aesthetic appeal that sets it apart from many other tarantula species. The most prominent feature is the iridescent blue or sapphire coloration that shimmers across its legs and carapace. This color is not always consistent, with the intensity varying based on factors like lighting, age, and the tarantula’s overall health. The body typically displays a dark coloration, often black or dark brown, providing a stark contrast to the vibrant blue legs. GSTs are a medium-sized species, with females reaching a leg span of up to 5-6 inches, while males tend to be slightly smaller. They are known for their relatively fast movements and their defensive behavior if provoked. Observing their behavior offers a deeper understanding of the creature.
Origin and Habitat

In the wild, Gooty Sapphire Tarantulas originate from the Indian subcontinent, specifically the Andhra Pradesh region. They are terrestrial spiders that construct burrows in the ground, often under rocks, logs, or among the roots of plants. The natural habitat typically features a humid environment, which is critical for their survival. They thrive in environments with moderate temperatures and a readily available food source, such as insects and other small invertebrates. Replicating this natural environment is paramount in captive care to ensure the tarantula’s health and longevity. Learning about their natural habitat is crucial to their appropriate care.
Creating the Perfect GST Enclosure
Creating a suitable enclosure is essential for the health and happiness of your Gooty Sapphire Tarantula. The enclosure should provide a secure and comfortable environment, mimicking the conditions of their natural habitat. Consideration must be given to the size of the enclosure, the type of substrate, the decoration, and the maintenance of appropriate temperature and humidity levels. A well-designed enclosure not only supports the spider’s physical needs but also provides enrichment, allowing it to exhibit natural behaviors like burrowing and web-spinning. It is an important aspect of the care you give to your pet.
Enclosure Size
The size of the enclosure is crucial, especially for a growing tarantula. A good rule of thumb is to provide an enclosure that is at least three times the tarantula’s leg span in length and width, and the height should be sufficient to allow for a few inches of substrate. For a juvenile GST, a container of approximately 8x8x8 inches is generally suitable. As the tarantula matures, the enclosure size should be increased accordingly. An adult female might require an enclosure of 12x12x12 inches or larger. The enclosure should always have secure ventilation to ensure proper airflow while preventing the tarantula from escaping.
Substrate and Decoration

The substrate serves as the foundation of the enclosure, providing a medium for burrowing and maintaining humidity. A mix of coco fiber, peat moss, and a small amount of vermiculite or sphagnum moss works very well. The substrate should be deep enough, typically 4-6 inches, to allow the GST to burrow comfortably. Decorations can enhance the environment by providing hiding places and enrichment. Cork bark, artificial plants, and sturdy hides are excellent options. These features allow the tarantula to feel safe and secure, which can reduce stress and promote healthy behaviors. Remember to avoid sharp or potentially hazardous decorations.
Temperature and Humidity
Maintaining the correct temperature and humidity levels is essential for the health of your Gooty Sapphire Tarantula. The ideal temperature range is between 75-85°F (24-29°C). A heat mat placed on the side of the enclosure can provide a gentle heat source, but avoid placing it directly under the enclosure to prevent overheating. Humidity should be maintained between 60-70%. This can be achieved by lightly misting the enclosure with dechlorinated water once or twice a week and ensuring there’s a shallow water dish. Proper ventilation is also necessary to prevent mold and maintain air quality. Use a hygrometer to monitor humidity levels.
Feeding Your Gooty Sapphire Tarantula
Providing the right diet is crucial for the growth and overall health of your Gooty Sapphire Tarantula. They are carnivorous and will primarily feed on insects. The type and size of insects, along with the feeding frequency, should be tailored to the tarantula’s age and size. A well-fed tarantula will be more likely to thrive and display its natural behaviors. It is a fundamental aspect of tarantula care, and a well-nourished tarantula is a healthy tarantula.
What to Feed GSTs

The diet of a Gooty Sapphire Tarantula should consist mainly of insects. Crickets, mealworms, and dubia roaches are excellent choices. For smaller or juvenile tarantulas, flightless fruit flies can be provided. Always ensure that the insects are gut-loaded with nutritious food prior to feeding them to your tarantula. This helps to ensure that the tarantula receives essential vitamins and minerals. Avoid feeding insects collected from the wild, as they may carry pesticides or parasites that can harm your tarantula.
Feeding Frequency
The feeding frequency depends on the tarantula’s age and size. Spiderlings and juveniles can be fed two to three times a week, while adult tarantulas can be fed once a week or every other week. Overfeeding can lead to obesity, which is detrimental to their health. Remove any uneaten insects within 24 hours to prevent stress to the tarantula and reduce the risk of mites. Observe your tarantula’s abdomen; a plump abdomen indicates it is well-fed, while a shrunken abdomen indicates it needs to eat.
Watering and Hydration
Providing a constant source of clean water is vital for the survival of your Gooty Sapphire Tarantula. Water is essential for hydration, molting, and overall well-being. Proper hydration ensures that the tarantula remains healthy and active. Access to clean water is a basic care requirement for any tarantula keeper.
Water Source

A shallow water dish is necessary in the enclosure. The water dish should be easily accessible to the tarantula and shallow enough to prevent the tarantula from drowning. Use a small, stable dish made of ceramic or plastic. Fill the dish with fresh, dechlorinated water. Change the water regularly, ideally every 1-2 days, to prevent bacterial growth. Small water dishes also allow the tarantula to drink without issues.
Misting and Humidity Control
In addition to a water dish, misting the enclosure can help to maintain the necessary humidity levels. Use a spray bottle filled with dechlorinated water. Lightly mist the enclosure once or twice a week, avoiding direct spraying of the tarantula. Be careful not to oversaturate the substrate, as this can lead to mold growth. Monitoring the humidity with a hygrometer is essential to ensure the correct levels are maintained.
Handling and Safety Precautions
Handling Gooty Sapphire Tarantulas is generally not recommended, as they can be skittish and defensive. Their bite, although not medically significant to humans, can be painful. It is generally better to observe the tarantula and handle them only when absolutely necessary, such as during enclosure maintenance. Safety should always be the priority when interacting with a GST.
Do GSTs Bite

Yes, Gooty Sapphire Tarantulas can bite if they feel threatened or are provoked. Their venom is generally not considered to be medically significant to humans, but a bite can be painful. The bite can cause localized pain, redness, and swelling. Avoid putting your fingers near the tarantula’s fangs. If bitten, wash the area with soap and water and monitor for any allergic reactions or complications. A bite is usually an indication that the tarantula is stressed or feels unsafe.
Handling Tips
Handling Gooty Sapphire Tarantulas is generally not recommended, but if it’s necessary, do so with extreme caution. If you must handle your tarantula, do so while sitting close to the ground to minimize the risk of injury if it falls. Use a wide, soft brush to gently guide the tarantula. Never grab the tarantula or try to force it to move. Always be mindful of their movements and be prepared for a quick escape. Wash your hands thoroughly before and after handling the tarantula. Always remember the safety of you and your tarantula.
Common Health Issues and Solutions
Like all pets, Gooty Sapphire Tarantulas can experience health issues. Understanding these potential problems and how to address them is critical to providing good care. Recognizing the early signs of illness can allow for timely intervention and increase the chances of a positive outcome. Regular observation and maintenance are the keys to keeping your tarantula healthy.
Moulting Process

Moulting is a natural process where the tarantula sheds its exoskeleton to grow. During this time, the tarantula will typically stop eating and may spend more time hiding. The tarantula will usually flip onto its back. Do not disturb the tarantula during moulting, as this can be detrimental. Provide adequate humidity to assist the moulting process. After moulting, wait a few days before feeding the tarantula, as its fangs will still be soft.
Parasites and Diseases
Tarantulas can be susceptible to certain parasites, such as mites. Mites can be introduced through the substrate or live insects. If mites are present, you may see them as small, moving dots on the tarantula or in the enclosure. Treat the infestation by changing the substrate and cleaning the enclosure thoroughly. Diseases in tarantulas are not very common, but if you observe unusual behavior or symptoms, it is best to consult with a veterinarian specializing in exotic animals. Ensuring the correct care reduces the likelihood of your tarantula experiencing diseases or parasites.
Breeding and Reproduction
Breeding Gooty Sapphire Tarantulas is a rewarding experience, but it is also a complex process. It requires a thorough understanding of tarantula behavior, the ability to provide proper care, and a commitment to ensuring the health of the spiders. Proper setup is key to successful breeding and raising the offspring. Breeding projects must be approached responsibly to ensure the welfare of the tarantulas.
Identifying Sex

Before breeding, it is crucial to determine the sex of your tarantulas. The most reliable method is to examine the tarantula’s exuviae (molted exoskeleton) after a moult. Male tarantulas have a distinct set of modified pedipalps (the small appendages near the mouth) that are used for mating. Females do not have these modifications, but they have a spermatheca, a structure used for storing sperm, which can be difficult to observe without a microscope. This process is usually done by an experienced tarantula keeper.
Mating and Egg Sac Care
Mating involves introducing a mature male to a receptive female. The process should be carefully supervised to avoid the female potentially attacking the male. If mating is successful, the female will produce an egg sac, which she will guard. The care of the egg sac involves maintaining appropriate temperature and humidity levels, and ensuring the female is well-fed. Once the spiderlings hatch, they should be separated into individual enclosures to prevent cannibalism. Breeding is a complicated and demanding process.
