Your Questions Answered
What size enclosure does this tarantula need?
An adult requires a secure, terrestrial enclosure with a minimum footprint of 18″ x 12″. Provide 5-6 inches of slightly moist substrate for burrowing. Cross-ventilation is important. This is not an arboreal species; floor space is more critical than height.
When will I see the purple coloration?
The vivid purple and pink hues are a sexually dimorphic trait of mature males. Males will display this coloration after their ultimate molt. Females and juveniles are typically a more subdued brown or black. We ship unsexed spiderlings; coloration develops with maturity.
How is its temperament for care?
This species has a defensive nature and can be fast and skittish. It possesses urticating hairs and will readily kick them if threatened. It is a display animal, not suited for handling. Feeding should be done with long tongs, and rehousing requires careful planning and respect for its speed.
