I will setup my acurite tomorrow to measure my tank's humidity but I feel it is low plus the fact Tuna is experiencing a bad shed.
I'm thinking about moving her to a tub and I have a few questions.

Would it improve the humidity if I don't have or plan on getting a rack to place the tub in? I would transfer my UTH from the tank to the tub.

Since the tub will probably be smaller, what kind of items should I place in it besides the hide and substrate?

Any other tips, suggestions or ideas are welcome.
