I tossed a poor anubias that got abused at walmart into my terrarium without any gradual reduction of water or anything. The tank gets misted twice a day and the anubias sits in a low spot with its roots buried in a deep bed of sphagnum moss. It has grown four new leaves and two more are budding. I would just empty the water and put some sphagnum moss in the tank and mist it a couple of times a day. The open air and better light (no water to reduce quality) will do wonders for those poor little plants.
