For what it's worth, I raised some Taiwan Beauty rat snakes many years back, but I can't say what the differences in requirements might be? I don't want to assume.
I lived in the desert when I had them & didn't measure their humidity per se, but their enclosures had large water bowls for them & they never had bad sheds. They
are more like a racer than a "rat snake"...meaning they're not good at sitting still, but I didn't find their temperament to be difficult...not biters*. I raised mine from c/b
hatchlings & bred them years later. The Taiwans are gold patterned with black (no "blue") & quite pretty, IMO. Very enthused consumers of f/t mice or rats, not fussy-
but they do have quite the "boarding house reach", lol. *They have some reputation for being nippy but like most snakes, it's up to the person raising them to
establish routines & gentle handling, so they know when it's food incoming & when it's not. I don't think that a w/c adult would be at all "fun", lol, but c/b are
readily available.
