My humidity levels keep going back down, it's very frustrating... I am hopping once the Zoo Med fogger arrives, it will help! We mist constantly, just to keep it at about 50%, which is not enough!
Our enclosure is in sort of a strange set up at this moment, hard to describe...Alex is working on a larger setup for her right now, we're making our own..
The bottom part is a 20 Gallon tank we had previously...(he originally wanted a chinese water dragon that could dive for its food & such) We purchased the fresh air terrarium 18 x 12 x 20.. We had originally thought it was bigger, and would completely cover the top of our tank.
There is a mesh screen topper on the aquarium, and my boyfriend cut a hole in it the size of the fresh air habitat, and mounted it it in place securely.
Yes, there is a water fountain in there, but only because originally, when we bought her, they told us she drinks from the fountain, and we would need one. We keep it on the side, to where her waste cannot drop into it. Also there is a fine mesh, the prevents her, or any feeders from getting into that side of the tank, we have a light to go over it, to help increase the humidity of the tank.
The substrate is a temporary thing, (another thing we were told she would need) until we have other methods of increasing humidity, it has been picked of any large peices though. I have several ground coverage plants to prevent her from accidently eating it, or really getting on it. I keep a good eye on it...once we have other means, I intend to just put the plant pots directly on paper towels. I thought that by keeping the aquarium on the bottom, it will act more as a rainforest really would, moist, damp and thick at the bottom ..and at the top, airy, light, and breezy with fresh rain.

Once we have a fogger we will drop the fog to the bottom and hopefully that will really help til we can get an automatic mister..(zoo med reptile fogger that sits OUTSIDE the cage - we are STILL on the search for our humidifier, stored in a closest somewhere around here)
All feeders are fed in the fresh air habitat, and monitored carefully, to ensure they do not find their way to the tank bottom, that's a major no no . LOL...
The moonlight is never on, I just turned it on to brighten up the bottom of the tank for the picture...Normally it's just a regular daylight, 60. So it doesn't get too hot in the bottom. If it's a cold night, we have a ceramic heater that sits underneathe the cage, it's a tall fat one, you can slightly see it in the reflection. but I've been playing with the timer and wires down there, trying to figure it all out. LOL
The large fake leaf in the back of the fresh air,is for the water drip, it falls directly into the ledge , into the drip cup, it worked out perfectly to prevent water falling into the aquarium.
I will add more jungle vines soon, that vine I have curved to go to the top of her tree, by the water drip leaf, and her feeder bowl.
The "wood" dish, lol..is meant for her feeder worms, so they do not fall to the bottom, she yums them right up as soon as she sees them lol.
Assortment of real plants, made for ground coverage, and one branch of fake leaves, to help dry and evaporate any water that falls onto the fabric.
