Crickets, roaches, and mealworms are common choices. Ensure the prey is appropriately sized for your tarantula to avoid stress or injury. Overfeeding can lead to accelerated growth, potentially causing health problems, while underfeeding will stunt growth. Observe your tarantula’s abdomen; if it is plump, it’s well-fed. Variety in the diet helps ensure proper nutrition. Supplements, like calcium, aren’t typically necessary if a balanced diet is provided.
Size and Age of the Tarantula
The growth rate of a Mexican Red Rump is also determined by its age and current size. Spiderlings grow relatively quickly, molting frequently. As they mature, the molting frequency decreases, and growth slows down. Adults typically molt only once a year or even less frequently. The size of the tarantula at the time of molting also affects its growth; each molt allows for a substantial increase in size. Understanding the different growth phases helps you adjust your care accordingly. Monitor your tarantula’s size and molting frequency to ensure it is growing at a healthy pace, making any necessary adjustments to its environment or diet.
Molting Process and Growth
Molting is a fundamental process for tarantula growth, and understanding the molting cycle is essential. It’s how these arachnids increase in size and shed parasites or damaged body parts. The frequency of molting varies based on the tarantula’s age, with younger tarantulas molting much more often. Each molt is a vulnerable time for your tarantula. Providing the right environment is essential to ensure they can shed their exoskeleton successfully. Improper care during this period can be dangerous, leading to health complications or even death. The molting process reveals a larger, softer body beneath the old exoskeleton, significantly impacting growth.
Signs of an Upcoming Molt

Knowing the signs of an upcoming molt allows you to prepare and minimize stress for your tarantula. Pre-molt behavior includes a loss of appetite, lethargy, and the tarantula may become less active. Their abdomen may appear darker and larger, and they might start to build a web mat or seal themselves in their burrow. Additionally, you may notice a change in color, as their old exoskeleton starts to separate from the new one forming underneath. These signs indicate that the molting process is about to begin. Recognizing these indicators will enable you to provide a safe and stable environment during this critical time, safeguarding the tarantula’s health.
What to Do During Molting
During the molting process, it’s crucial to avoid disturbing your tarantula. Refrain from feeding them, as they will not eat during this time. Maintain the correct humidity levels, as this assists in the shedding process. Ensure there are no hazards in the enclosure that could harm the tarantula during the molt. It is essential not to touch or handle the tarantula during or immediately after the molt, as their new exoskeleton will be soft and vulnerable. Once the tarantula has molted, and its new exoskeleton has hardened (usually a few days), you can resume regular care practices. The careful handling of the tarantula during this delicate period is essential.
Comparison with Other Tarantula Species
The growth rate of the Mexican Red Rump is generally considered moderate compared to other tarantula species. Some species, such as the Psalmopoeus irminia, grow much faster, while others, like the Grammostola pulchra, are known for their slower growth rates. The growth rate can also depend on factors such as the tarantula’s genetics and the specific care it receives. Understanding the typical growth patterns for different tarantula species can help you better appreciate the development of your Mexican Red Rump. Always research and understand the specific needs of your tarantula, as growth rates vary widely across different species and their care requirements.
