Common genera: Heteroscodra, Stromatopelma
Enclosure size for adults: The majority of these species stay a medium size (5-6in/12-15cm) as well as being arboreal, so they require an enclosure around 12×12×18in (30×30×40cm) as adults, at minimum.
Enclosure setup (décor, substrate, etc.): These species, although they are arboreal, will also burrow quite a bit. They should have substrate at least as deep as 2x their legspan, while also having tall hiding areas like a large piece of bark, where the tarantula can either hide inside or behind it. They will create a hiding area with webbing and debris, so they should have things like moss and leaf litter to add to their webs.
Humidity/moisture: These species generally prefer it on the drier side. Leave the substrate dry with a moist corner and a water dish.
