Lesserblack Tarantula Facts

Fact 1 Diet and Feeding Habits
Lesserblack Tarantulas are carnivores, and their diet primarily consists of insects. In captivity, they thrive on a diet of crickets, roaches, mealworms, and other commercially available feeder insects. The size of the prey should be appropriate for the tarantula’s size; younger tarantulas should be fed smaller insects, while adults can handle larger prey. Feeding frequency varies based on the tarantula’s age and metabolism; juveniles may need feeding every few days, while adults can be fed once or twice a week. Always remove any uneaten food to prevent the build-up of mold or mites. Providing a varied diet can also ensure that your tarantula gets the nutrients it needs to stay healthy. Proper nutrition is key to tarantula health.
Fact 2 Temperament and Handling
Colombian Lesserblack Tarantulas are generally known for their docile temperament, which makes them a relatively good choice for beginner tarantula keepers. However, it’s essential to remember that they are still wild animals and should be handled with caution. While they are not typically aggressive, they can bite if they feel threatened. Handling should be minimized and only done when necessary, such as during enclosure maintenance. When handling, do so close to the ground to minimize the risk of injury if the tarantula falls. Always wash your hands thoroughly before and after handling your tarantula. Respecting their space and understanding their behavior can help prevent incidents.
Fact 3 Ideal Habitat Setup

Creating the right habitat is crucial for the health and well-being of a Colombian Lesserblack Tarantula. The enclosure should be appropriately sized for the tarantula’s size, with juveniles needing smaller enclosures than adults. A glass or acrylic terrarium with a secure lid is ideal. The enclosure should include a substrate of substrate like coco coir, peat moss, or a mixture of the two, to a depth of several inches. This allows the tarantula to burrow, which satisfies its natural instincts. Providing a shallow water dish with clean water is essential, along with a hide or shelter, such as a piece of cork bark or a hollow log, to provide security. Maintaining the correct temperature and humidity levels, which are discussed in greater detail below, is also crucial for a healthy environment. A well-designed enclosure helps the tarantula thrive.
Fact 4 Molting Process
Molting is a natural process where tarantulas shed their exoskeletons to grow. During this process, the tarantula becomes vulnerable and should be left undisturbed. The frequency of molting depends on the tarantula’s age and growth rate; juveniles molt more often than adults. Before molting, the tarantula may appear lethargic and may stop eating. After molting, the tarantula’s new exoskeleton will be soft, and they will need time to harden. Never disturb a tarantula during its molting process, and avoid feeding until its fangs have fully hardened. Recognizing the signs of molting and providing a safe and undisturbed environment is key to the tarantula’s well-being during this crucial phase of its life. Molting is an essential aspect of their life cycle.
Fact 5 Common Health Issues
While Colombian Lesserblack Tarantulas are generally hardy, they can be susceptible to certain health issues. Parasites and mites can infest the enclosure, so it’s important to maintain a clean habitat. Mites can often be identified by their presence on the tarantula or substrate. Fungal infections can occur if the environment is too humid or poorly ventilated. Symptoms can include discoloration or lesions on the tarantula’s body. Proper husbandry practices, including maintaining appropriate humidity and temperature levels, providing a clean water source, and regularly removing uneaten food and waste, can help prevent these problems. If you notice any signs of illness, consult with a veterinarian experienced with invertebrates or a reputable tarantula expert. Prevention is key to keeping your tarantula healthy.
Fact 6 Breeding and Reproduction

Breeding Colombian Lesserblack Tarantulas in captivity can be a rewarding experience, but it requires knowledge and patience. Breeding typically involves introducing a mature female to a male’s enclosure. If the female is receptive, mating will occur. After mating, the female will construct an egg sac, which contains a large number of eggs. The egg sac needs to be incubated under carefully controlled conditions to ensure successful hatching. Raising spiderlings requires a great deal of care and attention. Breeding requires specific environmental controls. It’s a complex process but a fascinating one for those interested in expanding their knowledge of these creatures. Successful breeding results in more of these amazing creatures.
Fact 7 Conservation Status
The conservation status of the Colombian Lesserblack Tarantula is not currently evaluated by the IUCN. However, like many tarantula species, they face threats from habitat loss due to deforestation and the pet trade. Responsible pet ownership and supporting conservation efforts are essential to protect these amazing creatures. Buying captive-bred tarantulas helps reduce the pressure on wild populations. Being informed about their conservation status is vital for responsible pet ownership. Awareness and action can help preserve these beautiful spiders for future generations. Supporting conservation efforts is something to consider.
Caring for a Lesserblack Tarantula
Choosing a Healthy Tarantula

When choosing a Colombian Lesserblack Tarantula, it’s crucial to select a healthy specimen. Look for a tarantula that is active and alert, with a plump abdomen, indicating it is well-fed. Avoid tarantulas that appear lethargic, have missing limbs, or show signs of illness. Check for mites or other parasites. Buying from a reputable breeder or pet store is highly recommended to ensure the tarantula is healthy and has been properly cared for. Inquiring about the tarantula’s history, including its age, feeding habits, and any previous molts, can provide valuable information. A healthy start is essential for a thriving tarantula.
Creating a Suitable Enclosure
As mentioned above, the enclosure should be appropriately sized for the tarantula’s size. A ten-gallon tank or similar sized enclosure is suitable for juveniles, while adults require a larger enclosure, such as a 20-gallon long tank. The enclosure should have a secure lid to prevent escapes. The substrate should be several inches deep to allow for burrowing and should be made of coco coir, peat moss, or a mixture of both. Provide a water dish with clean water, ensuring it is shallow enough to prevent drowning. A hide, like a piece of cork bark or a hollow log, should be provided for the tarantula to retreat to. Maintaining appropriate temperature and humidity is also crucial for a healthy environment. Setting up the perfect enclosure is key to a happy tarantula.
Feeding and Watering
Feeding your Colombian Lesserblack Tarantula requires careful attention. Offer a variety of appropriately sized insects, such as crickets or roaches. Juveniles should be fed more frequently than adults. Remove uneaten food within 24 hours to prevent mold or mite infestations. Fresh, clean water should always be available in a shallow dish. Regularly check the water dish and refill it as needed. Proper hydration is essential for your tarantula’s health. Adjust your feeding schedule based on the tarantula’s age, size, and activity level. Overfeeding can lead to health problems, so it is important to be mindful of your tarantula’s needs. Proper feeding is an important aspect of care.
