Environmental Conditions
The environmental conditions in the GBB’s natural habitat are key to their survival. These spiders prefer warm temperatures, typically ranging from 75-85°F (24-29°C), and low humidity levels, around 60-70%. The dry environment helps prevent fungal growth and other diseases. GBBs are often found in areas with sparse vegetation, such as shrubs and low-lying plants. These environmental conditions significantly impact their activity levels, molting frequency, and overall health. Replicating these conditions in captivity is crucial for their well-being. Providing the right balance of heat, humidity, and a suitable substrate is key to maintaining a healthy GBB.
GBB Fact 3: Temperament and Behavior
GBBs are generally considered a more skittish tarantula species. They are known for their speed and agility. They are not particularly aggressive, but they can be defensive and will readily retreat to their burrows or flick urticating hairs (small, irritating hairs) as a defense mechanism. While they are beautiful, they are not ideal for frequent handling. Understanding their temperament is important for safe and responsible ownership. Their behavior in the wild provides clues on how they will react to different situations. The way they interact with their environment gives insights into their needs and how to best care for them.
Defensive Mechanisms

The GBB has several defensive mechanisms. Their primary defense is their speed; they can quickly retreat to their burrow when they feel threatened. They will also flick urticating hairs from their abdomen. These hairs can cause skin irritation and discomfort if they come into contact with the skin. In rare cases, they may bite, but this is usually a last resort. Recognizing these defensive behaviors is important when interacting with them. Always handle them with care and respect to minimize stress and the risk of defensive reactions. Understanding these mechanisms provides insight into their behavior and enables safer handling practices.
Activity Levels
GBBs are typically most active during the evening and nighttime hours. They often spend the day hidden in their burrows or under shelter, emerging at dusk to hunt and explore their surroundings. This nocturnal behavior is a common adaptation among tarantulas. Their activity levels can be influenced by environmental factors, such as temperature and humidity. A well-maintained environment that provides the right conditions can promote natural behaviors. Observing their activity patterns is a fascinating aspect of owning a GBB and provides insight into their needs.
GBB Fact 4: Diet and Feeding
The GBB is a carnivore and primarily feeds on insects in the wild. Their diet consists of a variety of prey, including crickets, roaches, and other small invertebrates. Understanding their dietary needs is crucial for providing proper care in captivity. A balanced diet supports their overall health and growth. Careful attention should be paid to the size of the prey to prevent injury or choking. Feeding your GBB is a very important part of its care and well-being. The right food will keep them happy and healthy.
Food Preferences

In captivity, GBBs readily accept a variety of insects. Crickets and roaches are common staples, and they also enjoy mealworms, superworms, and even small pinkie mice (for adults, but with caution). Variety in their diet can provide a wider range of nutrients. The size of the prey should be appropriate for the size of the tarantula. Always ensure that the prey is pesticide-free and healthy. Providing a varied and nutritious diet is a key aspect of responsible GBB ownership. You can provide food that offers both nutrition and enrichment for the spider.
Feeding Frequency
Feeding frequency depends on the age and size of the GBB. Spiderlings and juveniles should be fed more frequently, approximately 2-3 times per week. Adult GBBs can be fed every 1-2 weeks. It’s important to remove any uneaten food within 24 hours to prevent mold growth. Always provide a shallow dish of fresh water. The feeding schedule should be adjusted based on the tarantula’s appetite and condition. Overfeeding can lead to obesity, while underfeeding can stunt growth.
