    Brachypelma auratum, commonly known as the Mexican Flame Knee, is a beautiful species of tarantula native to Mexico.

It's a relatively docile species that can make a great pet for both beginners and experienced keepers.

    Housing

    Enclosure Size:

     

  • The enclosure should have more horizontal than vertical space to reduce the risk of falls. We would recommend any of the Terrestrial Enclosures we have in the shop.

    •  

    We recommend the following:

  • 0.5"-1": Terrestrial Sling Crib 
  • 1"-3": Small Slider or Small Cuboid
  • Full size adult: Large Slider, Large Cuboid, or Large Coffin.
  • If you wish to go a bit overboard, you can do the Terrestrial XL but for this species it is not needed at all.


    •  

    Substrate:

  • Use a deep substrate (at least 4-6 inches) such as coconut fiber (coir), peat moss, or a mix of the two. This allows the tarantula to burrow, which is important for its natural behavior and well-being.
  • Make sure the substrate is slightly moist but not soaking wet. It helps maintain humidity and provides a natural environment.
  •  We recommend the Arachnidirt in our shop.

    •  

    Hide:

  • Provide at least one hide (e.g., a small cave or hollow log) for your tarantula to retreat to when it feels stressed or wants privacy.
  • Plants (live or artificial) and branches can be added for enrichment but make sure the tank doesn't get overcrowded. The tarantula needs space to roam and feel secure.
  • We have a ton of great accessories.

    •  

    Climbing: 

    • primarily terrestrial, so no need for tall climbing structures.

    Ventilation:

    • Ensure proper ventilation to prevent mold but avoid drafts.

    Temperature and Humidity

     

  • Daytime Temperature: Keep the temperature between 75°F to 85°F (24°C to 29°C).
  • Nighttime Temperature: A drop to about 70°F (21°C) is fine.
  • Avoid temperature fluctuations or keeping them in drafty areas.

    •  

    Diet

    • A shallow water dish should always be available with fresh water, especially in a dry environment.

    • The Mexican Flame Knee is an opportunistic predator, and its diet primarily consists of live insects.

      • Prey items: Crickets, locusts, mealworms, dubia roaches, and other appropriately sized insects.
      • Feeding frequency: Juveniles should be fed 2-3 times per week, while adults can be fed once a week.
      • Offer food items that are no larger than the width of the tarantula's body to prevent feeding issues.

    Temperament/Personality

    • Brachypelma auratum is generally docile and can tolerate light handling, but it is still important to be cautious. Handling should be kept to a minimum to reduce stress.
      • While not particularly aggressive, if threatened, they may bite. A bite is unlikely to be deadly to humans but can be painful, with symptoms such as redness, swelling, and discomfort. They are also known to kick urticating hairs from their abdomen if threatened.

    Molting

  • During molting, your tarantula may refuse food and appear lethargic. Do not disturb it during this time.
  • After molting, provide extra humidity and warmth to help the new exoskeleton harden.
  • It's common for younger tarantulas to molt every 6-12 months, while adults molt less frequently.

    Cleaning and Maintenance

    • Spot Clean: Remove uneaten prey and feces regularly to prevent mold or mites.
    • Full Cleaning: Change the substrate and clean the enclosure every 6 months or when it appears dirty.

     

    General Notes

    • Burrowing: While they may not always burrow, providing enough substrate allows them to do so if they wish.
    • Lighting: No special lighting is needed, but avoid direct sunlight or extreme heat sources.
