Identity confidence: provisional. This is a genus, group, or trade name rather than a confirmed species. Treat it as the closest match we can stand behind, and use the more conservative end of any range.
Curly Hair & Red Rump Tarantulas: Advanced Care Guide
Keeper Snapshot: The genus the curly hair belongs to (split from Brachypelma in 2019): placid, hardy, dry-leaning New World terrestrials that grow noticeably faster than true Brachypelma. Adults reach about 5-6.5 inches across; females are long-lived (15-25 years).

Use This Guide Safely
- Confirm the exact animal. Match this guide to the species, locality, size, and life stage on your label. If the ID is uncertain, use the more conservative part of the range and ask before changing the setup.
- Change one thing at a time. Treat temperature and humidity as target zones, then watch posture, burrowing, drinking, feeding, and molt behavior before making another adjustment.
- Respect the handling boundary. If the guide says no handling, fast, defensive, or medically significant, plan transfers with catch cups, locked lids, and no bare hands. For serious bites, stings, or symptoms, seek emergency medical care.

Enclosure Format / Size Class
- Compact secure enclosure while it's a tiny sling
- Horizontal terrestrial burrow setup for juveniles
- Larger floor-space terrestrial build for the adult
Warnings First
- Urticating hairs: T. albopilosus is far less flicky than Brachypelma; T. vagans is the defensive one
- Opportunistic burrower. Give substrate depth
- Heavy-bodied terrestrial. Keep the enclosure low so a fall can't rupture the abdomen
- A low enclosure vents badly at floor level. Put vents low on two opposite walls so the moist half stays a half rather than spreading across the whole substrate.
Simple Care
- Dry-leaning substrate with a water dish; keep one corner lightly moist for the curly hair.
- Put pebbles in the dish so slings cannot drown.
- Vents low on two opposite walls so air crosses the floor and holds the dry/moist split.
- Substrate deep enough to start a burrow.
- Expect medium growth, not the glacial pace of true Brachypelma.
Advanced Keeper Notes
Enclosure & Microclimate
- Tliltocatl was carved out of Brachypelma in 2019 (Mendoza & Francke): T. albopilosus (curly hair: the hobby's classic 'first tarantula'), T. vagans (Mexican red rump), T. kahlenbergi, T. epicureanus, T. sabulosus, T. verdezi.
- Standard New World terrestrial setup with substrate deep enough for an opportunistic burrow. T. vagans burrows more readily and tolerates drier conditions; T. albopilosus and T. kahlenbergi appreciate a slightly moister half.
- That moister half only stays a half if air is crossing the floor. Because these are kept in low enclosures for fall safety, lid vents mostly exchange the thin band above the spider rather than around it. Put vents low on two opposite walls, at or just above the substrate, so the dry side actually stays dry. Without that, the split evens out within a couple of weeks and you end up keeping a dry-leaning genus uniformly damp.
- Ventilation and ambient humidity are one setting. Feed moisture in on one side and from the dish, then let airflow carry it off, rather than closing the enclosure up. Ambient will sit at 50 to 65% and can drift lower without concern, since these drink from the dish.
- Judge by hand rather than by gauge. The moist half should hold shape when squeezed with no free water; the dry half should read dry. If you cannot feel the difference between the two sides, add airflow.
- Keep the dish full and put pebbles or coarse grit in it so the waterline sits below the rim. Slings drown in adult-scaled dishes, and this is a genus commonly bought as a first tarantula at sling size.
- Wet the moist half under the hide or at the burrow entrance rather than misting the enclosure. A humid pocket where the spider actually sits beats a uniformly damp box, and it leaves the dry side and the airflow intact.
Feeding, Growth & Maintenance
- Strong, reliable feeders: slings and juveniles weekly, adults every week or two. Don't power-feed into an oversized abdomen.
- The 'Nicaraguan true vs Honduran/hobby-form' T. albopilosus question is the longest-running ID debate in the hobby; care is the same either way.
- Molting: a premolt tarantula turns sluggish, seals up, and refuses food for days or even weeks. Pull any uneaten feeders, leave it strictly alone, and wait 5-10 days after the molt (until the new fangs and exoskeleton harden) before feeding again.
Possible Origin / Range
- Likely native range: Mexico and Central America: cloud forest and humid lowlands of Honduras, Nicaragua and Costa Rica (T. albopilosus); drier forests of Veracruz and the Yucatán (T. vagans, T. kahlenbergi).
- Habitat translation: Dry-leaning terrestrial enclosure with a water dish, substrate deep enough for an opportunistic burrow, and a slightly moister corner for the more humidity-tolerant species.
Advanced Keeper Details
- Adult size ~5-6.5 in DLS; medium growth: distinctly faster than true Brachypelma, with T. albopilosus the quickest of the former Brachypelma; females ~15-25 years, males ~4-6.
- T. albopilosus is genuinely one of the best first tarantulas: placid, hardy, forgiving. T. vagans is the skittish/defensive member of the group; the rest sit in between.
- Like all former Brachypelma, Tliltocatl is CITES Appendix II: buy captive-bred and keep provenance/paperwork.
