Lots of people who keep Brachys, Aphonopelma and I guess other terrestrial species have noticed the daily climbing antics. That's why we have it drummed into us that the substrate has to be high enough to prevent a fall great than 1.5 of the tarantula's DLS. I'm beginning to think that just because a species is terrestrial doesn't mean it wont climb. And if the species hails from forest land like the auratum perhaps even more so!
