Well, I go to UT Austin in Austin, Texas, so the humidity tends to be on the mid to higher side. I'd say average is about 55%, but it's pretty variable. Today it was 75%. I don't know about the inside of my apartment, though. Perhaps that would have an effect on the efficacy of a tank? I do care about the aesthetic, but only insofar as it allows me to give the snake good care. If it is possible to provide the same quality of care and to make the snake as comfortable with a tank as with a tub, even if that requires a heat lamp, I think I would lean toward that option.
