For your humidity u can take a piece of plexiglass cut it so it fits inside the lip of the tank. Then cut about three in off. throw a few hinges at the bottom where the two pieces meet. And a few cabinet locks on at the top drill some air holes and glue the little piece on and pow u have a secure lid. Then turn it on it's side and ur humidity prob is gone. It cost me twenty dollars and about an hour to do mine. And it looks better than a screen lid.
