Enclosure and maintenance
Adults reach about 17–18 cm (6.5–7 in). Grammostola pulchripes is a terrestrial species, so the enclosure should prioritise usable floor space, a snug ground-level retreat and enough substrate to keep fall height low.
With Grammostola pulchripes, routine care should not involve handling. Arrange the water dish, retreat and door so feeding and cleaning can be done without repeatedly disturbing the spider.
Growth, feeding and moulting
Growth is moderate. Feed to the spider's size, appetite and abdomen rather than forcing a rigid weekly schedule; the routine will change as Grammostola pulchripes grows.
If Grammostola pulchripes refuses food and shows premoult signs, remove live prey, keep water available and leave it alone. There is no need to make a spider in normal premoult eat.
Lifespan and buying one
Chaco Golden Knee females often live around 15 years or longer; males live around 5 years. An unsexed youngster can therefore become either a relatively short or a much longer commitment.
If sex matters when buying Chaco Golden Knee, ask how it was confirmed. For enclosure planning, a measured leg span is more useful than hobby labels such as juvenile or sub-adult.
