Yep, sounds like he is stressed - and could also have a bacterial infection, so I would still get fecals tested, etc.

I don't really consider subocs to be fragile, but they are "sensitive" in some ways. I think they need a definite quiet and dark night period, and they should not be kept in high traffic areas.

You might also try blocking at least three walls of the snake's cage - the less exposed the better in my opinion.
