Enclosure and maintenance
Adults reach about 12–14 cm (4.75–5.5 in). Ephebopus cyanognathus 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 Ephebopus cyanognathus, 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 Ephebopus cyanognathus grows.
If Ephebopus cyanognathus 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
Blue Fang Skeleton 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.
A sexed Blue Fang Skeleton 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.
