Good Morning,

We can just leave your post here......it's ok. Welcome to Frog Forum!

There was a thread yesterday with very similar questions.
I think you should find answers to all of your questions here:

Except, your question regarding ventilation. I don't recall discussing this.
Personally, I remove all of the screen from the top of the exo tanks and replace it with glass. ( photo in the link above) It is an easy fix ( if I can do it ...anyone can). I buy cheap picture frame glass as you don't want to get anything w/ UV protection. If you should need any help with this ... post your question here ...throw me a PM to give me a heads up

Remember, there are vents under the front doors and you will be opening the doors 1-2 times daily to feed.
Plus, there are the vents in the lid for cords and mist tubing. However, be careful if you are housing thumbnail darts , juvenile or small frogs as they can fit through that opening; especially the thumbs ! They are little Hudini frogs if they can get out ....they will !

Chime in if you should have any additional questions !
