About
The Madera Canyon Black - an ebony montane Aphonopelma from a sliver of the Santa Rita Mountains, Arizona, described in the great 2016 US revision. Cool-tolerant by descent (mountain nights are cold), easy by genus tradition: calm, dry-kept, slow-growing, decades-lived. Narrow natural range means CB stock is limited and treasured - UK slings at around £40 vanish quickly. A bulletproof, jet-black American classic in miniature.

Madera Canyon Black - a complete husbandry sheet. Use as a starting point and adjust to your individual specimen.
What size enclosure does a Madera Canyon Black Tarantula need?
Adults
30 × 25 cm (12 × 10 in) for a mature adult. Floor space matters more than height.
Slings & Juveniles
House spiderlings in small, appropriately sized deli cups or sling enclosures.

What temperature and humidity does a Madera Canyon Black Tarantula need?
Heating
The Madera Canyon Blacks is comfortable at 20-26 °C and tolerate cool nights naturally - no supplementary heat in UK homes.
Humidity
40-55 %: dry substrate and a full water dish.
Ventilation
Cross-ventilation is essential - side-vented enclosures, never stagnant.
What substrate is best for a Madera Canyon Black Tarantula?
Recommended Mixes
Depth
5-8 cm
Notes
Keep substrate dry. Pack firm for stable décor.
How do you set up a Madera Canyon Black Tarantula enclosure?
Décor
The Hide
A cork bark half-log or leaning slab retreat.
Water
Always provide a shallow fresh water dish.
Lighting
No special lighting needed. Ambient room light is enough.
How often should you feed a Madera Canyon Black Tarantula?
Good Feeders
Long refusal worrying you? Separate premoult fasting from genuine problems with our "Is my T okay?" checker.
Is my Madera Canyon Black Tarantula dying or moulting?
Pre-moult signs to look for
Refusing food for weeks is normal before a moult - a healthy Madera Canyon Black Tarantula fasting is almost never an emergency in itself. Watch for slowing down and spending more time in the hide, laying a thick moult mat of web on the floor. New World species like this one often show a bald spot on the abdomen that darkens to near-black as the new skin underneath readies - a darkening bald patch is a reliable countdown, not a disease.
On its back is MOULTING, not dying
A Madera Canyon Black Tarantula lying upside down or on its side with legs curled inwards is almost certainly mid-moult. Do not touch it, do not right it, do not mist it - just remove any live prey (crickets can kill a defenceless moulter) and leave the room.
How long between moults?
For this species, expect a moult roughly every 30-60 days for spiderlings, every 85-135 days for juveniles, and every 190-300 days for sub-adults, with adult females moulting around every 11.7 months (up to 17.3 months at the extreme). Males never moult again after their ultimate (mature) moult.
After the moult: fang hardening time
The new exoskeleton stays soft, with fangs that cannot grip, for roughly 8 days in this species. Offer no food and no handling for about 8 days - feeding too early is how fresh moulters get injured. The shed exuvium is also the best sexing tool there is - see our tarantula sexing guide for what to look for.
Genuinely worried about behaviour that is not moulting? Our "Is my T okay?" triage tool walks the danger signs one by one.
What ongoing care does a Madera Canyon Black Tarantula need?
🪞 Moulting
Signs: refuses food, abdomen darkens and goes glossy, becomes sluggish. Do not disturb; keep water available; wait until the fangs are black and hard before feeding again. Adult intervals apply to mature FEMALES - a mature male never moults again.
🧹 Cleaning
Daily: check the water dish. Weekly: remove uneaten prey boluses and spot-clean.
✋ Handling
Calm and slow - a tolerant species. Handle rarely and low.
