Low humidity is a common problem with aquariums. Tanks are designed to hold large quantities of water...not humidity

so how can you bump up your humidity if it's too low?

When I had a tank, I used a wired mesh top. To fix my humidity, I would take a bath towel and wet it every morning...

wring it out, fold it up, and place it on top of one half of the cage top. It won't be an immediate change, but within an hour or so, you will notice a big change in the humidity.

One other common solution I see is to wrap screen top in aluminum foil.

Try both methods and do what works for you. Get first hand experience in what works and what doesn't, and then pass your experience on
