Well, first off a scientific name helps But since it's a horned baboon, that means that it's most likely Ceratogyrus. These guys are kept much like usumbara as they're from the same type of habitat. Avg temps and low humidity for adults. For slings, AVG temps and a bit more humid than the adults. Too much humidity is not good for this species. Agressiveness is the same as most baboon spiders, watch out if you mess with it. They're fairly defensive.
Well, it probably is the same species... "C.bechuanicus" as Arachnocenter described. Weather or not Paul Becker identified it right remains a mystery, as he isn't known for his knack for identifying spiders. But write that down for your records.
