Aphonopelma gabeli
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.
Carlsbad Green Tarantula: Advanced Care Guide
Keeper Snapshot: A Chihuahuan Desert native and about as forgiving as tarantulas get. Keep it at 70-80F on 3-4 in of dry packed substrate with an anchored hide and a full water dish, and it will largely look after itself. The supplied animals are subadult to adult, so the slow years are already behind them. Calm enough for a first tarantula, native enough to be genuinely interesting, and dry enough that the only real way to kill it is to keep it wet. Keep it spicy. - Big Z

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.
Quick Snapshot
| Temperature | 70-80F working room range. Ordinary indoor night drops into the 60s are normal and beneficial for a species from a high-desert climate with sharp diurnal swings. No supplemental heat is needed in a normally heated home. |
|---|---|
| Humidity | No numeric % target, and lean dry. Manage by method: keep the surface dry, keep a pebble-filled water dish full, and ventilate low. This is a desert species and standing damp substrate is the primary captive killer. If the enclosure needs moisture at all, add it to one lower corner and let it dry back fully. |
| Setup Type | Dry desert terrestrial with a scrape or shallow burrow |
| Substrate | 3-4 in of dry, firmly packed coco fiber and topsoil or another additive-free soil mix. Packed firmly enough to hold a scrape. Anchor a cork hide over a started depression. Keep the fall zone short - a heavy-bodied adult terrestrial should not be able to climb higher than roughly its own diagonal leg span. |
| Feeding | Supplied subadult to adult animals: one appropriately sized cricket or roach every 10-14 days, adjusted by abdomen condition. Juveniles: weekly. Prey no longer than the spider's body. Remove uneaten prey within 24 hours and withhold entirely through premolt until fangs are dark and the exoskeleton is firm. Long voluntary fasts with a healthy abdomen need no intervention. |
| Care Difficulty | Spice 2: Beginner |
| Handling | Not recommended. Catch cup transfers only. |

Enclosure Format / Size Class
- Spiderling: compact enclosure, dry substrate with one lightly moist corner, openings narrower than the animal
- Juvenile: low terrestrial grow-out, 3 in packed dry substrate, anchored hide
- Subadult to adult (the supplied animals): low horizontal enclosure with generous floor, 3-4 in packed substrate, full-body hide, minimal height
Warnings First
- Damp substrate is the number one cause of death in captive desert Aphonopelma. When in doubt, drier.
- Docile does not mean handleable. It has urticating hairs and a fall can rupture the abdomen. Catch cup transfers only.
- Adults kick hair rather than biting when pushed. Keep loose hairs away from eyes and airways during maintenance.
- Slow growth and months-long fasts are normal for the genus and are not signs of illness.
- Wild-collected North American Aphonopelma are subject to state collection rules. Keep provenance records for native stock.
Simple Care
- Room temperature is fine. 70-80F with an ordinary night drop, no heat mat.
- Low horizontal enclosure, 3-4 in of dry firmly packed substrate, anchored cork hide.
- Keep it dry. This is the whole husbandry challenge for a desert Aphonopelma.
- Cross-ventilate low on two opposite walls at substrate level.
- Keep a pebble-filled water dish full at all times.
- Feed every 10-14 days at this size and adjust by abdomen condition.
- Keep the enclosure low. Falls injure heavy terrestrials.
Advanced Keeper Notes
Enclosure & Microclimate
- North American Aphonopelma are kept dry with a permanent water source. The operating decision is a dry surface plus a full dish rather than any humidity percentage, consistent with Big Z's other Aphonopelma guides.
- Floor area over height. Height is a hazard for a heavy-bodied terrestrial and this species does not climb by preference.
- A natural indoor night temperature drop matches the sharp diurnal swing of its native range and requires no equipment to reproduce.
Feeding, Growth & Maintenance
- Cadence is conservative genus-level practice keyed to abdomen condition rather than a species-specific published schedule.
- At subadult to adult size the animal is on the slow end of the feeding range; overfeeding a desert Aphonopelma is more common than underfeeding.
- Post-molt timing uses physical checks - dark fangs, firm exoskeleton, normal movement - rather than a day count.
Possible Origin / Range
- Likely native range: Chihuahuan Desert of southern New Mexico and west Texas, in the country around Carlsbad. The supplier provided no collection locality for the purchased animals, so no finer origin claim is made.
- Habitat translation: High Chihuahuan Desert becomes a low horizontal enclosure with dry packed substrate, a shallow anchored retreat, strong low ventilation, an ordinary indoor temperature range with a natural night drop, and a permanent water dish. Labeled synthesis of general North American Aphonopelma captive practice and Big Z's house standards.
Advanced Keeper Details
- Aphonopelma gabeli Smith, 1995 is the accepted name. Recent revisions of North American Aphonopelma have consolidated many nominal species, so trade material sold under this name may represent a broader regional complex; the identity is recorded as supplier-stated.
- The olive-to-bronze cast over the carapace is the trade-distinguishing feature and is most visible on a freshly molted animal.
- No sex or formal life stage was supplied. The subadult-to-adult lane is taken from the supplier's own wording on the invoice.
