Size and growth
Adult Tliltocatl albopilosus reach about 15–17 cm (6–6.5 in) and are slow growers. Adult Tliltocatl vagans reach about 14–16 cm (5.5–6.25 in) and are moderate growers. That affects how quickly Curly Hair Tarantulas and Mexican Red Rumps move through sling and juvenile enclosure sizes.
Do not use size alone to estimate age in either Tliltocatl albopilosus or Tliltocatl vagans. Sex, feeding and individual variation can change the pace of growth even when two spiders began at a similar size.
Enclosure and lifestyle
Curly Hair Tarantulas are terrestrial, while Mexican Red Rumps are terrestrial. Build the Tliltocatl albopilosus enclosure for a terrestrial spider and the Tliltocatl vagans enclosure for a terrestrial spider instead of assuming two tarantulas need the same shape of setup.
For Tliltocatl albopilosus, substrate depth, retreat position and usable space should match its terrestrial lifestyle. Apply the same rule separately to Tliltocatl vagans; the enclosure should make normal behaviour easy rather than forcing either species into a generic layout.
Temperature, water and moisture
A practical temperature range for Tliltocatl albopilosus is 20–25°C works well; stability matters more than chasing a single number; for Tliltocatl vagans, it is 20–26°C. Stable room conditions are more useful for both species than chasing small fluctuations within those ranges.
For Tliltocatl albopilosus, use water dish at all times; allow the surface to dry while maintaining a modest moisture gradient, especially for slings. For Tliltocatl vagans, keep a water dish available and maintain a modest moisture gradient; avoid persistently wet substrate. In both enclosures, keep fresh water available and adjust substrate moisture to how quickly the setup actually dries.
Temperament and maintenance
Tliltocatl albopilosus is a New World species, while Tliltocatl vagans is a New World species. That background is useful when planning maintenance, but individual Curly Hair Tarantulas and Mexican Red Rumps can still differ noticeably in speed and defensiveness.
With both Tliltocatl albopilosus and Tliltocatl vagans, locate the spider before opening the enclosure, use long tools when they make the job safer and keep a catch cup ready for rehousing. Handling is not required for routine care.
Male and female lifespan
Male Tliltocatl albopilosus generally live around 4–6 years, while females can live 20 years or more; long-lived females are common in captivity. Male Tliltocatl vagans generally live roughly 4–6 years, while females can live 15–20 years.
Those lifespan ranges make sex particularly relevant when comparing Tliltocatl albopilosus with Tliltocatl vagans. A confirmed female of either species is normally a much longer commitment than a mature male, and the exact age of an older juvenile may be impossible to know.
UK availability and trade notes
In the UK hobby, Tliltocatl albopilosus is currently classed as common, while Tliltocatl vagans is classed as common. Stock changes between specialist sellers, captive-produced batches and show weekends, so availability should be checked at the time of purchase.
For records and purchases, use the scientific names Tliltocatl albopilosus and Tliltocatl vagans as the main identifiers. Current trade notes list Tliltocatl albopilosus as 'CITES trade controls apply' and Tliltocatl vagans as 'CITES Appendix II; UK Annex B', so check current requirements before any international movement where controls may apply.
Practical difference in day-to-day care
The practical difference between Tliltocatl albopilosus and Tliltocatl vagans comes from the combination of lifestyle, adult size, growth and moisture needs. Those factors change how much substrate, vertical space and maintenance access each enclosure needs.
Whichever species you keep, let the individual spider settle into an enclosure designed for its own biology. That applies equally to Tliltocatl albopilosus and Tliltocatl vagans: fresh water, secure housing and patient observation matter more than trying to make the two species behave the same way.
