Marshalli Tarantula Care Tip 1: The Ideal Enclosure
The enclosure is the cornerstone of your Marshalli tarantula’s well-being. A properly designed setup provides a safe and comfortable environment, allowing your pet to thrive. Several factors need consideration when choosing the right enclosure including size, ventilation, and substrate. This tip will help you create an ideal habitat that mimics their natural environment and supports their physical and psychological needs. Investing time and effort in setting up the perfect enclosure is an investment in your tarantula’s long-term health and happiness.
Choosing the Right Tank Size
The size of the enclosure should be appropriate for the size of your Marshalli tarantula. A general guideline is to provide an enclosure that is at least twice the tarantula’s leg span in width and length. A juvenile Marshalli can start in a smaller enclosure, such as a 5-gallon tank, and be upgraded as they grow. Adult females will typically require a larger enclosure, such as a 10-gallon or even a 20-gallon long tank. A larger enclosure provides more space for burrowing and exploration, which can enhance their quality of life. Ensure the enclosure has a secure lid to prevent escape, as tarantulas are excellent climbers.
Substrate Selection for Comfort and Burrowing
The substrate is the material that covers the bottom of the enclosure and serves several critical functions, including providing a comfortable surface for the tarantula to walk on and offering a medium for burrowing. The best substrate for a Marshalli tarantula is a mixture of about 70% coco fiber and 30% peat moss or a similar blend. This combination retains moisture while still allowing for good drainage, creating a suitable environment for burrowing. The substrate depth should be at least 4-6 inches deep, especially for juveniles and females, as they tend to burrow. Regularly check the substrate for any signs of mold or excessive moisture, and replace it periodically to maintain a healthy environment. Avoid substrates like cedar or pine shavings, as they can be toxic to tarantulas.
Providing Adequate Ventilation
Proper ventilation is crucial for maintaining a healthy environment and preventing the buildup of mold and bacteria. The enclosure should have adequate ventilation holes on the sides and/or top. Ensure the ventilation is sufficient to allow for air circulation but not excessive, which can lead to the enclosure drying out too quickly. Cross-ventilation, where air can flow in one side and out the other, is ideal. Avoid placing the enclosure in direct sunlight, as this can cause excessive heat buildup and make the enclosure uninhabitable for your Marshalli tarantula. Regularly monitor the enclosure to ensure the ventilation is appropriate and adjust as needed.
Marshalli Tarantula Care Tip 2: Perfecting the Environment
Creating the right environmental conditions is critical for the health and well-being of your Marshalli tarantula. This involves careful management of temperature and humidity, mimicking their natural habitat. Precise control will help them thrive in captivity and live a long, healthy life.

Temperature and Humidity Control
Marshalli tarantulas thrive in a specific range of temperature and humidity. Maintaining these environmental conditions is crucial for their well-being. Monitoring and adjusting these factors as needed will help ensure your tarantula’s health. Consistent temperatures and humidity levels will contribute to their proper molting and overall health.
Maintaining Optimal Humidity Levels
Humidity levels should be maintained between 60-70% for Marshalli tarantulas. This can be achieved by lightly misting the substrate once or twice a week, depending on the ventilation in the enclosure and the humidity of the environment. Avoid over-misting, which can lead to mold growth. You can monitor the humidity levels using a hygrometer. The humidity level is also affected by the type of substrate you choose. A proper substrate, such as coco fiber, will help retain moisture and maintain the desired humidity levels. Providing a shallow water dish is another way to contribute to the overall humidity.
Creating a Temperature Gradient
A temperature gradient is essential, as it allows your tarantula to move to different areas of the enclosure to regulate its body temperature. The ideal temperature range for a Marshalli tarantula is between 75-85°F (24-29°C). You can achieve this gradient by placing a heat source, such as a low-wattage heat mat, on one side of the enclosure. Avoid placing the heat source directly under the enclosure, as this can create hot spots. Use a thermometer to monitor the temperature on both sides of the enclosure, ensuring there are no extreme temperature fluctuations. Ensure the heat source doesn’t dry out the enclosure; adjust accordingly to maintain appropriate humidity.
Marshalli Tarantula Care Tip 3: Feeding Your Tarantula
Feeding your Marshalli tarantula correctly is essential for their health and growth. The right food sources, feeding frequency, and portion sizes are important considerations. Following these guidelines ensures your tarantula receives the nutrition it needs while preventing potential health problems. A well-fed tarantula is a healthy tarantula. Learning the proper feeding methods is a critical aspect of responsible tarantula care.
Best Food Sources for Your Marshalli
Marshalli tarantulas are insectivores and primarily eat live insects. The best food sources include crickets, mealworms, dubia roaches, and occasionally, superworms. Ensure the insects are gut-loaded with nutritious food, such as fresh vegetables and fruits, before feeding them to your tarantula. This practice enhances the nutritional value of the meal. Avoid feeding wild-caught insects, as they may carry parasites or pesticides. Always remove uneaten food within 24 hours to prevent the growth of mold and bacteria. Supplementing the diet with a vitamin and calcium supplement for insects can be beneficial, particularly for growing tarantulas.
Feeding Frequency and Portion Sizes
The feeding frequency depends on the age and size of the tarantula. Spiderlings should be fed 2-3 times a week. Juvenile tarantulas can be fed once a week, while adult tarantulas can be fed once every 1-2 weeks. Observe your tarantula’s abdomen; it should be plump but not overly distended. The portion size should be appropriate for the tarantula’s size. Generally, offer insects that are roughly the same size as the tarantula’s body. Overfeeding can lead to health problems, so it’s essential to find the right balance. Always adjust the feeding schedule based on the tarantula’s appetite and condition.
Providing Fresh Water
Providing a constant supply of fresh, clean water is crucial. Use a shallow water dish that is easily accessible. The water dish should be shallow enough to prevent drowning. Change the water regularly, at least once a week, to prevent the growth of bacteria. For smaller tarantulas, you can use a bottle cap or a cotton ball soaked in water. This ensures your tarantula stays hydrated and healthy. Always make sure the water is clean, as it is essential for their survival.
Marshalli Tarantula Care Tip 4: Handling and Safety
Handling a Marshalli tarantula should be approached with caution. These spiders are generally docile, but they can bite if they feel threatened.
