I've been looking at Tarahumaras as well. I really like them a lot, and as for care, I'm pretty sure it's the same care requirements as a regular BCC or BCI considering they're just different localities of the same two subspecies. The only major difference is the enclosure size.

Then again, I could be wrong. I haven't found very much info on Tarahumaras specifically.

They are gorgeous lil animals, though.
