Enclosure and maintenance
Adults reach about 12–14 cm (4.75–5.5 in). Ceratogyrus darlingi is a fossorial species, so the enclosure should prioritise deep, compactable substrate, a secure starter burrow and enough depth for the spider to stay underground.
With Ceratogyrus darlingi, plan routine maintenance so your hands do not need to share the spider's space. Keep a catch cup and long tools ready before opening the enclosure.
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 Ceratogyrus darlingi grows.
If Ceratogyrus darlingi 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
Rear Horned Baboon females often live 8–12 years; males live roughly 2–4 years. An unsexed youngster can therefore become either a relatively short or a much longer commitment.
A sexed Rear Horned Baboon label is only as useful as the evidence behind it. Ask how the sex was confirmed and get a measured size rather than relying on juvenile or sub-adult.
