Tapinauchenius sanctivincenti
St Vincent Featherleg Tarantula: Advanced Care Guide
Keeper Snapshot: A Caribbean arboreal built around speed, not danger: no urticating hair, not aggressive, just very fast. The challenge is containment, not husbandry. Plan every rehouse in a closed room with the route cleared first.

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.

Humidity zones: Very Low under 30% - Low 30-60% - Low-Moderate 40-70% - Moderate 60-80% - Moderate-High 70-85% - High 80%+ - Very High 90%+
Enclosure Format / Size Class
- Sling: small tall enclosure with a vertical anchor, openings narrower than the animal, lightly moist.
- Juvenile (2.5-3 in): tall enclosure, full-height cork, 2-3 in substrate, strong ventilation.
- Adult: tall build sized to your animal, full-height anchored cork, upper and lower vents, secure lid.
Warnings First
- Speed is the hazard: among the fastest tarantulas kept. Assume it bolts every time the enclosure opens.
- Rehouse in a closed room with the door shut, the floor clear, and the destination enclosure already open and positioned.
- No urticating hair and no reputation for aggression; it's trying to leave, not bite, but that still ends with a lost spider.
- No handling at any size.
- Stagnant wet air is the main husbandry killer; if choosing between more moisture and more airflow, choose airflow.
- Do not disturb the silk retreat; a stressed animal that abandons it will pace and is more likely to bolt.
Simple Care
- Hold 72-80°F, steady, no sharp night drop.
- Height over floor space: anchor a vertical cork slab reaching most of the enclosure.
- 2-3 in of floor substrate for moisture and fall cushioning, not for digging.
- Ventilate hard: cross-ventilation plus upper vents. Stagnant humid air kills arboreals.
- Keep the water dish full; dampen one lower area when the substrate dries out.
- Feed weekly at this size; expect an immediate, enthusiastic response.
- Treat every opening as a containment problem: closed room, cleared route, catch cup ready.
Advanced Keeper Notes
Enclosure & Microclimate
- Vertical anchor placement determines whether it settles: give a slab it can silk behind, not an open surface it must sit exposed on.
- Vent both low and high so air actually moves through the column instead of sitting still at the top where the spider lives.
- Floor substrate is for humidity buffering and fall cushioning only; depth is wasted on this genus.
Feeding, Growth & Maintenance
- Cadence follows abdomen condition rather than a fixed schedule.
- Feeds aggressively and grows fast for a New World arboreal; expect frequent molts and plan rehouses ahead.
- Judge post-molt readiness by dark fangs, a firm exoskeleton, and normal movement rather than a day count.
Possible Origin / Range
- Likely native range: Saint Vincent, in the Lesser Antilles.
- Habitat translation: Caribbean forest tree hollows and bark crevices become a tall enclosure with anchored vertical cork, a shallow moisture-holding floor, moderate humidity, and hard cross ventilation.
Advanced Keeper Details
- Tapinauchenius sanctivincenti is the accepted name. Short iridescent setae shift from chestnut to bronze to purple, strongest right after a molt.
- Spice 4 here reflects containment risk, not venom or temperament.
- Size lane is set from your animal's measured size, since no formal life stage was given.
