A hardy, attractive New World terrestrial tarantula with crisp white "zebra" leg striping, native to Central America. Skittish and a quick burrower but with mild venom — a popular, forgiving beginner species.

Part of the Tarantulas
Theraphosid spiders kept as low-maintenance display invertebrates. New World species are generally docile with mild venom but bear irritating urticating hairs, while Old World species lack those hairs but tend to be fast, defensive, and have more potent (though rarely life-threatening) venom.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Juvenile / sub-adult enclosure
8 × 8 × 8 in (juvi) → 10 × 10 × 8 in (sub-adult)
Clear acrylic or glass enclosure with cross-ventilation, 3–4 in of dry coco-fibre or topsoil mix, a cork-bark hide, and a shallow water dish. Floor space matters more than height for terrestrials; the spider should be able to turn around comfortably. Costa Rican zebras are skittish but non-defensive Aphonopelma seemanni — they like slightly humid substrate and will burrow as juveniles.

Recommended
Adult terrestrial enclosure
12 × 12 × 8 in (≈ floor 3× adult DLS)
Adult floor space targets roughly three times the diagonal leg span so the spider can web, walk, and ambush. Add 4–5 in of substrate, a half-log hide, low decor, and a water dish; height stays modest to prevent a fatal fall onto the abdomen.

Ideal
Naturalistic terrestrial vivarium
14 × 10 × 10 in, bioactive
A bioactive footprint with deeper substrate (5–6 in), leaf litter, a sculpted hide, and one or two live hardy plants. Cleanup crew (springtails, isopods) keeps the dry-but-not-arid microclimate stable for long-term welfare.

Egg
These invertebrates lay eggs — often in a guarded clutch, a silk sac (spiders), or a brood (carried by female isopods). The eggs are small and soft and develop without a true larval or pupal transformation.

Juvenile
Juveniles hatch as miniature versions of the adult and grow by molting their exoskeleton (or, in snails, by enlarging the shell). They gain size, segments, or leg pairs and gradually take on adult coloration with each molt.
Adult
Adults reach full size and reproductive maturity with the species' mature form and coloration. Many arachnids and myriapods continue to molt as adults, and sexes can differ in size or in specialized appendages.
Habitat & enclosure
Terrestrial with burrowing tendencies: a floor space around 30 x 20 cm suits an adult, with 10-15 cm (4-6 in) of substrate to dig. Provide a cork bark hide. Keep at 24-28 C (75-82 F). Humidity is moderate (60-70%); keep one corner of substrate damp and a water dish full — this species tolerates a drier surface than rainforest species. No UVB needed.
Substrate
Deep, slightly moist coco fiber/peat (or coco-soil) at least 10-15 cm deep so it can burrow; keep the surface on the drier side with one damp corner. Pack it firmly enough to hold a burrow and provide a cork bark starter.
Equipment & setup
Low, wide terrestrial enclosure with a secure lid and cross-ventilation, deep substrate, cork bark hide, a shallow water dish, and a hygrometer/thermometer. Supplemental heat on a thermostat only if the room is cool. A catch cup and forceps are useful for this fairly fast, skittish species.
Diet
Insectivore. Feed crickets, dubia roaches, locusts, or mealworms sized to the spider — slings every few days, adults roughly weekly. A reliable eater that often ambushes from its burrow. Remove uneaten prey within a day and stop feeding when the spider enters pre-molt.
Behavior & temperament
A New World terrestrial with urticating hairs on the abdomen, which it kicks when threatened; it is more prone to bolting and burrowing than to biting. Venom is mild. Often skittish and may dash for its burrow rather than stand its ground. Tolerant of careful keepers; handling is discouraged but bites are uncommon and not medically serious. A good display and first-tarantula species.
Health
Very hardy and long-lived (females can exceed 15-20 years). Main risks are falls (keep enclosure height low for a terrestrial), excessive dampness with poor ventilation, and dehydration if the water dish runs dry. Urticating hairs can irritate keeper skin/eyes. Fasts and seals up before molting — leave it undisturbed and don't feed.
Tips, DIY & hacks
Keep the enclosure low and wide — terrestrials can be injured by falls from height. Offer a pre-started burrow and expect the spider to disappear underground, especially around molts. Maintain a humidity gradient (one damp corner) rather than soaking everything. Its bold white striping shows best against dark substrate and good lighting.
