Enclosure and maintenance
Adults reach about 13–15 cm (5–6 in). Psalmopoeus reduncus is an arboreal species, so the enclosure should prioritise usable height, a vertical cork retreat, web anchors and safe access to the water dish.
With Psalmopoeus reduncus, 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 Psalmopoeus reduncus grows.
If Psalmopoeus reduncus 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
Costa Rican Orange Mouth females often live 10–12 years; males live roughly 3–4 years. An unsexed youngster can therefore become either a relatively short or a much longer commitment.
Before buying Costa Rican Orange Mouth, get two concrete details: how any claimed sex was established and the spider's current measured size. Those are more useful than a vague life-stage label.
