Humidity from tank

[Eixa]

My aquatic tank is making my room too humid, but if I get a lid I'm worried about my tank getting too hot. Is there a way to let heat out, but not moisture?

If you have newts/axolotls in the tank there shouldn't be any heat in there?! They are cold water animals so the water should be at room temperature with minimal evaporation.

Cold water can evaporate too, albeit more slowly.

But I guess finding a way to make my tank colder would solve my problem perfectly.

Where is the tank situated? Does the sun shine on it?
