The Singapore Blue Tarantula (Chilobrachys dyscolus) is a captivating species, popular among tarantula enthusiasts for its vibrant coloration and interesting behaviors. Understanding its size is crucial for proper care and appreciation of these fascinating creatures. This guide provides key facts about the size of the Singapore Blue Tarantula, from average measurements to factors affecting their growth. Whether you are a seasoned keeper or a curious beginner, this information will help you gain a deeper understanding of these beautiful spiders. The size of your Singapore Blue Tarantula can also be used to determine the approximate age of the tarantula, as with each molt they grow in size. Keep in mind that proper care is also necessary for the tarantula to be able to grow into its full potential.
Average Size
On average, the Singapore Blue Tarantula reaches a size that makes it relatively small compared to some other tarantula species. The average size gives us a general understanding, which is usually helpful when determining the appropriate size of the enclosure that it will inhabit. The Singapore Blue Tarantula’s size is usually around 4 to 5 inches in leg span. However, the exact size can vary depending on various factors, as they do not all grow to be the same size. With proper care, many Singapore Blue Tarantulas can grow to be this size, so it is not something that you should worry about if you are seeing a small tarantula, it just means it is still young, or maybe the genetics are different. The size is still impressive and makes for an amazing pet.
Size of Males

Male Singapore Blue Tarantulas are typically smaller than females. They mature faster and, as a result, do not undergo as many molts as the females. The males are known to have a leg span of around 3 to 4 inches. These males often exhibit slightly different coloration, though it is not as noticeable as the color difference between the sexes of some other tarantula species. Male Singapore Blue Tarantulas are also more active and tend to wander more, which makes them a bit more interesting to watch, though it can make them escape from their enclosure. When determining the size of your tarantula you must also check the leg span, males might appear smaller because their legs are thinner and their overall body is not as large.
Size of Females
Female Singapore Blue Tarantulas are generally larger and live longer than males. They can reach a leg span of around 4 to 5 inches or sometimes even slightly larger with exceptional care. This size difference is typical in many tarantula species, with females investing more energy in growth. Females tend to have a more robust body build, and their overall appearance is bulkier than the males. The larger size of the female often makes them more desirable as pets because of their impressive size and the fact that they live longer. The female Singapore Blue Tarantulas can live for up to 15 years in captivity, while the males live for about 3 to 5 years.
Factors Influencing Size
Several factors influence the ultimate size of a Singapore Blue Tarantula. Understanding these can help owners optimize care for their tarantulas. Genetics, nutrition, and environmental conditions play critical roles in the spider’s growth and overall health. Providing the right conditions from the start can ensure your tarantula reaches its full potential. Always make sure you are taking care of your pet tarantula, because without the right conditions, the tarantula can die, or not grow to its full potential, leaving you with a smaller tarantula.
Genetics and Lineage

The genetic makeup of a tarantula significantly impacts its size. Some tarantulas simply have the genetic potential to grow larger than others, even within the same species. The lineage of a tarantula can influence its growth rate and ultimate size. It is important to source your tarantula from a reputable breeder to understand the genetic background of your spider. The genetics also affect the color of the tarantula, if they are very brightly colored or duller. When looking for a spider, make sure you look for the perfect match for you, and your preferences, as each spider is a unique animal.
Feeding and Nutrition
A well-balanced diet is crucial for tarantula growth. Providing appropriate food items, such as crickets, roaches, and mealworms, ensures your tarantula receives necessary nutrients. The frequency of feeding should be adjusted based on the tarantula’s age and size. Young tarantulas require more frequent feeding, while adults can be fed less often. A tarantula that is not fed properly will experience slower growth, and can even become ill. Make sure to do research and provide the best food for your pet to help them grow and become as healthy as possible. When they molt, this is also a good time to start feeding, as this is the fastest growth period.
Environmental Conditions
The environmental conditions within the enclosure are also important. Maintaining the correct temperature and humidity levels is critical for a tarantula’s well-being and growth. Incorrect environmental conditions can hinder growth and may lead to health problems. You should always monitor the environment, and adjust as needed. Proper ventilation is also important to prevent the growth of mold and mildew, and to allow for proper breathing for the tarantula. The best environment for your tarantula should be one that mirrors its natural habitat, allowing the tarantula to thrive, which is why it is important to do proper research before keeping one.
Growth Stages and Molting

Tarantulas grow by molting, shedding their exoskeleton. This process is essential for their growth. The frequency of molting decreases as the tarantula ages. Young tarantulas molt more often than adults, because they need to grow more rapidly. Molting is a vulnerable time for tarantulas, and it is important to provide a safe environment during this process. Molting can be a stressful time, so it is best to leave the tarantula alone during this time. Once the tarantula sheds its old skin, it will appear much larger.
Size During Molting
Before molting, a tarantula will often stop eating and may become lethargic. During this time, the tarantula’s new exoskeleton is forming underneath the old one. You might notice the tarantula’s abdomen appearing darker or more swollen before molting. After molting, the tarantula’s size will increase, because of the new exoskeleton. It is important to keep the humidity in the enclosure at the correct level during molting. The new exoskeleton of the tarantula will be soft, so it is best to leave the tarantula alone until it hardens.
Frequency of Molting
Young tarantulas molt several times a year, while adults molt less frequently. The frequency depends on the tarantula’s age, growth rate, and environmental conditions. As tarantulas get older, molting becomes less frequent, sometimes only once a year or even less. Each molt is a sign of growth and a milestone in the tarantula’s life. You should always document each molt, and its size. This will help you monitor the growth of the tarantula, as well as determine any issues there might be. Molting frequency can also be affected by the amount of food they are getting, which is why the feeding and nutrition is so important.
Comparing Singapore Blue Tarantula Size

The size of the Singapore Blue Tarantula can be compared to other species and the conditions in which they are kept. This comparison helps to provide context. It can help keepers understand how their tarantula’s size relates to its overall health and well-being.
Compared to Other Tarantula Species
Compared to some other tarantula species, the Singapore Blue Tarantula is considered of a smaller size. For example, the Goliath Birdeater (Theraphosa blondi) is one of the largest tarantulas, reaching leg spans of over 10 inches. Other species, such as the Pinktoe Tarantula, are smaller, with leg spans of around 5 to 6 inches. The Singapore Blue Tarantula is in a middle range when it comes to its size, which is good for some people. They are small enough that it is easy to care for, and have a good size. The different sizes also come with different colors, so it is very easy to find one that meets your needs.
Size in Captivity vs. Wild
Tarantulas in captivity may sometimes reach a slightly different size than those in the wild. Captive tarantulas often benefit from a consistent diet and stable environmental conditions, which can support optimal growth. In the wild, tarantulas face more challenges, such as fluctuating food supplies, predators, and environmental stressors, which may affect their growth. Overall, the size of the Singapore Blue Tarantula can be very impressive in captivity. You can help them grow by providing the right environment, food, and space to thrive.
Caring for a Singapore Blue Tarantula

Proper care is essential for a Singapore Blue Tarantula to reach its full size potential and live a long, healthy life. Understanding the environmental needs, as well as the feeding schedule, will help any owner provide the best care possible. It will also help with proper growth, leading to a healthy and happy spider. The proper habitat and maintenance are crucial for the spider to live a long life.
Enclosure Requirements
The enclosure should be appropriately sized for the tarantula’s size and provide adequate space. A good rule of thumb is the enclosure should be about three times the tarantula’s leg span in length. The enclosure should include substrate, such as coco fiber, to maintain humidity and allow the tarantula to burrow. Make sure that the enclosure can hold humidity, but still allows for some airflow, as this is the best way to ensure that your tarantula is going to be healthy. The enclosure should also include a water dish for hydration, and a hide or shelter where the tarantula can feel secure. Providing these resources can greatly improve the quality of life for the tarantula.
Feeding Schedule
The feeding schedule should be adjusted based on the tarantula’s age and size. Young tarantulas should be fed more frequently, around once or twice a week, while adults can be fed every one to two weeks. Provide appropriately sized prey items, such as crickets or roaches, and remove any uneaten food within 24 hours to prevent mold or mites. Always observe your tarantula’s feeding habits and adjust the schedule accordingly. If the tarantula is not eating, that could be a sign that it is getting ready to molt, or it could be a sign that it is sick. You must always check, and do the proper research.
