Tliltocatl albopilosus
Curly Hair Tarantula
Curly hair tarantulas are among the calmest, most commonly recommended beginner tarantula species, valued for their tolerance of husbandry variation and their unhurried, easy-to-observe temperament.

Life stages and changing needs
Expanded care guidance · Updated 7 October 2026 · Not professionally reviewed
Young animals and settling in
Young spiders moult more frequently than mature adults and need appropriately sized prey and safe access to moisture. A tiny spiderling’s enclosure must prevent escapes without sacrificing ventilation. Growth occurs through moulting, not a predictable monthly timetable. Record sheds and feeding, and avoid disturbing an animal that begins sealing its retreat or refusing food before a moult.
Adult care and reproductive changes
Adult females and mature males can have very different remaining lifespans and activity patterns. A mature male may roam and feed less; that does not justify repeatedly adding prey. These terrestrial spiders need secure ground-level hides and limited fall height. Housing alone prevents cannibalism and removes the need to manage unsafe social introductions.
Later life and changing needs
Long-lived females may have increasingly long intervals between moults. Continue watching abdomen condition, hydration and movement without imposing a mammal-style senior diet. A prolonged fast can be normal in some circumstances, but dehydration, injury or an abnormal curled posture needs specialist advice. Keep photographs and dated observations for a professional assessment.
Diet and feeding
Appropriately sized crickets or roaches every one to two weeks for an adult; juveniles take smaller prey more often
Feed responsibly sourced invertebrate prey sized for the spider. Do not offer pesticide-exposed garden insects or prey capable of overpowering the animal. Remove uneaten live prey, especially around a moult, because a vulnerable spider cannot defend itself normally. These spiders do not need bowls of human food or routine vitamin powder on prey.
Judge portions by abdomen condition and the feeding record rather than offering food every time the spider moves. Leave it undisturbed through the moult and wait until the new exoskeleton and fangs have hardened before resuming feeding; the interval depends on size and species. Ask an experienced specialist if you cannot judge readiness safely.
Daily care and ongoing checks
Every day
Check the water supply, enclosure security, ventilation and substrate each day without dismantling the retreat. Provide species-appropriate moisture rather than copying a tropical setup for every tarantula. A water dish should be safely accessible; water gels and sponges are not a substitute for hygienic water provision. Remove prey remains and visible mould carefully.
Regular maintenance and prevention
Observe rather than handle. A short fall can rupture the abdomen, and defensive hairs can irritate eyes, skin and airways. Keep the enclosure away from young children and other pets. Plan access to an exotic veterinarian or experienced invertebrate specialist before an emergency; do not pull an animal out of its old skin or apply household adhesives.
Behaviour and compatibility
Kicking urticating hairs from the abdomen when threatened rather than biting, burrowing, silk-lining retreats
- With children
- Not a child's handling pet; the urticating hairs can cause skin and eye irritation, and any bite carries venom
- With other animals
- Solitary housing only
- Training difficulty
- Not applicable
Health
- Dehydration in low humidity
- Injury from falls during handling or escape, which are frequently fatal for tarantulas
- Failed or stuck moults
Very few vets treat invertebrates; an exotics vet with invertebrate experience should be identified before acquiring one
Special care requirements
Avoid handling wherever possible, as falls from even modest heights are frequently fatal to tarantulas due to their fragile exoskeleton
Terrestrial stability and ground-level safety
Curly hair tarantulas are terrestrial spiders that need plenty of floor area for moving and digging, not excessive height, which can pose a dangerous fall risk. They are generally docile and manageable, provided the environment is kept clean and stable, and they are not disturbed frequently. A fall of even a short distance can rupture the abdomen and kill a heavy-bodied terrestrial tarantula, so the enclosure should have deep substrate and no tall decor it could climb and drop from. This species is often recommended to beginners because of its calm temperament, but handling should still be minimal and close to the ground — a startled tarantula can flick irritating hairs or bolt, and the spider's safety matters more than the keeper's wish to hold it.

Can your home meet curly hair tarantula needs?
- Plan for a lifespan of Females 10–15 years, males 3–5 years, including holiday cover and, where one is available, a vet familiar with this species. Lifespan ranges are not guarantees.
- Arrange the social setting before arrival. Social guidance for this species: Solitary; must be housed alone as adults are cannibalistic toward each other. Do not assume another animal of any species is a suitable companion.
- Habitat priority for this species: Floor area more important than height, as this is a ground-dwelling species. Make sure your setup can provide this consistently. Measure temperatures and humidity with thermometers and a hygrometer rather than guessing.
- Key care point: Avoid handling wherever possible, as falls from even modest heights are frequently fatal to tarantulas due to their fragile exoskeleton. Discuss diet and any specialist needs with the supplier, rescue and a vet who treats this species, and check local legal requirements before acquiring an animal.
