Vertical space
Arboreal species like Caribena versicolor and Avicularia climb. Provide a tall enclosure with a vertical cork slab or branches reaching toward the lid, where they'll build a silken tube retreat.
Ventilation is everything
The most common cause of arboreal losses is stagnant, overly humid air. Aim for cross-ventilation (vents on opposite sides) and let the enclosure dry out between light mistings rather than keeping it constantly wet.
