N. Chromatus
Species Name: Nhandu chromatus
Common Name(s): Brazilian Red and White Tarantula
Native Habitat:
Origin: Brazil and surrounding regions in South America
Environment: Tropical to subtropical forest edges and grasslands with moderate humidity and warm temperatures
Natural Behavior: Terrestrial—often found on the ground, sometimes near the base of vegetation or natural debris
Enclosure Setup
Enclosure Size:
Terrestrial Setup: Floor space at least 3–4 times the tarantula’s leg span in length and width, with limited enclosure height to reduce injury risk from falls.
Ensure adequate ventilation to maintain airflow and prevent mold.
Substrate:
Substrate Depth: Several inches (3–4 inches or more) of coco fiber or a topsoil mix to accommodate light burrowing or scraping.
Keep the substrate slightly moist but not saturated; allow partial drying on the surface.
Hides & Decor:
Provide at least one suitable hide (cork bark half-log, clay pot) for security.
Include decor like smooth rocks or artificial plants, ensuring no sharp edges.
Water Dish:
Offer a shallow water dish.
Refresh water regularly, keeping it clean and free of debris.
Environmental Conditions
Temperature:
Ideal Range: 70–80°F (21–27°C).
Typical room temperatures are usually sufficient; avoid extended drops below 65°F (18°C).
Humidity:
Aim for moderate humidity around 60–70%.
Light misting once or twice a week if needed, while ensuring proper ventilation to prevent mold.
The presence of a water dish helps maintain proper humidity.
Lighting:
No special lighting required.
Ambient room light is sufficient; avoid continuous bright, direct lighting.
Feeding
Diet:
Offer live insects such as crickets, roaches, or mealworms.
Prey size should be about equal to or slightly smaller than the spider’s abdomen.
Feeding Frequency:
Juveniles: Feed 1–2 times per week.
Adults: Every 1–2 weeks.
Remove uneaten prey after 24 hours to maintain cleanliness and minimize stress.
General Care & Behavior
Temperament:
N. chromatus can be skittish and sometimes defensive. It may show threat postures if disturbed.
They may flick urticating hairs when stressed.
Handling:
Handling is not recommended due to their defensive nature and potential hair flicking.
If moving is necessary, use a catch cup and soft brush for gentle herding.
Molting:
Reduced feeding and increased hiding often precede molting.
After molting, wait at least a week before offering food to allow the exoskeleton and fangs to harden.
Health Indicators:
A healthy N. chromatus typically has a well-rounded abdomen and steady feeding habits.
Watch for lethargy, refusal of food outside pre-molt periods, or a shriveled abdomen. Consult experienced keepers or an exotic veterinarian if concerned.
Maintenance
Cleaning:
Spot-clean leftover prey and waste promptly.
Full substrate changes are rarely needed; only if mold or pests appear.
Keep the water dish clean and filled.
Record Keeping:
Track feeding, molts, and enclosure maintenance.
Monitor temperature and humidity, adjusting conditions as necessary.
Species-Specific Notes
N. chromatus is known for its striking red and white coloration and somewhat more defensive demeanor.
Good for keepers who have some experience with New World species that possess urticating hairs.
