Enclosure and maintenance
Adults reach about 18–20 cm (7–8 in). Phormictopus cancerides 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 Phormictopus cancerides, 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 fast. Feed to the spider's size, appetite and abdomen rather than forcing a rigid weekly schedule; the routine will change as Phormictopus cancerides grows.
If Phormictopus cancerides 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
Hispaniolan Giant Tarantula females often live 12–18 years; males live roughly 3–5 years. An unsexed youngster can therefore become either a relatively short or a much longer commitment.
If sex matters when buying Hispaniolan Giant Tarantula, ask how it was confirmed. For enclosure planning, a measured leg span is more useful than hobby labels such as juvenile or sub-adult.
