New World Ground & Dwarf Tarantula Care Essentials
New World ground tarantulas span dry-surface species, moisture-dependent burrowers and very small dwarf species. Use the species notes below to select the right starting arrangement.
Representative catalog photo; follow the notes for your animal.
Enclosure & shelter
Prioritize usable floor area, a stable hide and diggable substrate. Limit fall distance and avoid hard, pointed furnishings. Size the enclosure and ventilation openings to the actual spiderling or adult; a large adult display can be unsuitable for a tiny dwarf sling.
Water, moisture & temperature
Provide a clean, shallow drinking dish and choose substrate moisture for the species and life stage. Many Aphonopelma, Grammostola and Brachypelma adults use relatively dry surfaces; Theraphosa and Ephebopus require a different moisture-retaining refuge. Do not convert those differences into one universal humidity percentage.
Feeding & molting
Use suitable captive-bred insects and vary portions with size, condition and molt cycle. Remove uneaten live prey. Protect yourself from irritating hairs when working around substrate and silk; never blow into the enclosure.

Keeper FAQs
Why has my tarantula stopped eating?
Premolt, maturity, season, disturbance and unsuitable conditions can all contribute. Check water and the enclosure before repeatedly offering prey.
It is on its back—is it dead?
A tarantula may molt on its back. Do not flip it over or touch it.
When can it eat after molting?
Wait for a hardened animal with functional, darkened fangs. Recovery time varies with size and species.
Do all New World tarantulas have the same defensive hairs?
No. Defensive structures and behavior vary; never use that broad label as a handling guarantee.
Everyday care checks
Check containment, drinking access and the animal's condition each day. Use captive-bred feeder insects appropriate to its size, remove leftovers and keep a record of feeding, molts and enclosure changes. Separate new arrivals from established animals and keep specimens individually as the default.
Keep pesticide sprays, scented cleaners and treated furnishings away from enclosures. Avoid direct sun and uncontrolled heat. A thermometer measures temperature; a humidity reading cannot tell you whether a burrow is dry, saturated or structurally stable.
Observe without handling. Do not force open sealed retreats or disturb a molting animal. Persistent weakness, injury or an unsuccessful molt needs experienced veterinary assessment rather than repeated improvised changes.
These guides explain care principles and important exceptions. A listing name does not independently identify a specimen, and related animals can need different conditions. For uncertain stock, ask Isopod King for its established care and provenance before choosing equipment.
