B. Hamorii
Species Name: Brachypelma hamorii
Common Name(s): Mexican Red-Knee Tarantula
Native Habitat:
Origin: Pacific coast of Mexico
Environment: Semi-desert scrubland with moderate seasonal humidity and warm temperatures
Natural Behavior: Terrestrial—commonly found on or near the ground under rocks, logs, or within shallow burrows
Enclosure Setup
Enclosure Size:
Terrestrial Setup: Floor space at least 3–4 times the tarantula’s leg span in length and width, with limited height to prevent injury from falls.
Ensure proper ventilation to maintain a clean, stable environment.
Substrate:
Substrate Depth: Several inches (3–4 inches or more) of a coco fiber or topsoil mix to allow for light burrowing.
Keep substrate slightly moist but not wet; top layers may dry out while maintaining subtle humidity in lower layers.
Hides & Decor:
Provide at least one suitable hide (cork bark half-log, clay pot) for security.
Smooth rocks or artificial plants can be included, ensuring no sharp edges.
Water Dish:
Offer a shallow water dish.
Change water regularly to keep it fresh and clean.
Environmental Conditions
Temperature:
Ideal Range: 70–80°F (21–27°C).
Normal room temperature is typically adequate; avoid extended periods below 65°F (18°C).
Humidity:
Aim for moderate humidity around 60–65%.
Light misting once or twice a week if needed, ensuring proper ventilation to prevent mold.
The presence of a water dish helps maintain humidity.
Lighting:
No special lighting required.
Ambient room lighting is sufficient.
Avoid direct, continuous bright light on the enclosure.
Feeding
Diet:
Live insects such as crickets, roaches, or mealworms.
Choose prey about the size of the spider’s abdomen or slightly smaller.
Feeding Frequency:
Juveniles: 1–2 times per week.
Adults: Every 1–2 weeks.
Remove uneaten prey after 24 hours to prevent stress and maintain cleanliness.
General Care & Behavior
Temperament:
B. hamorii is known for its generally docile nature, making it a popular beginner species.
They rarely show defensive behavior unless provoked and often remain calm when disturbed.
Handling:
If necessary, handle cautiously and close to a soft surface.
Use gentle techniques; avoid squeezing or restraining the tarantula.
Limit handling to reduce stress on the animal.
Molting:
Expect periods of fasting and reduced activity before molting.
After molting, wait about one week before feeding again to allow exoskeleton and fangs to harden.
Health Indicators:
A healthy B. hamorii maintains a plump abdomen and predictable feeding habits.
Watch for lethargy, long-term refusal of food (outside pre-molt), or a shrunken abdomen. Consult experienced keepers or an exotic veterinarian if concerned.
Maintenance
Cleaning:
Spot-clean uneaten prey and waste promptly.
Complete substrate changes are seldom needed; only if mold or pests appear.
Keep the water dish clean and filled.
Record Keeping:
Track feeding dates, molts, and any changes to the enclosure.
Monitor temperature and humidity levels if desired, adjusting as needed
