Normal
I have not observed this behavior in any of my other Brachypelma including vagans, albiceps, hamorii, smithii, albopilosum, or boehmei. Yes, they do climb around sometimes, but the auratum alone are almost always up on the decorations or the walls. I've tried experimenting with wetter or drier substrates to see if that had something to do with it, and it doesn't seem to in the case of my two B. auratum.
