I have a query.

I have an unused tank that is approximately 30"x12"x12".
I would like to make it into a vertical vivarium, but I'm not sure if it's actually possible.

I need a high humidity viv, with a little ventilation. I need a lot of climbing area as this will be for my crested gecko and in the future I might turf him out to another viv and use it for a tree frog.

My thought is, if I block off the bottom 6 inches with a piece of something (perhaps wood) siliconed in, then put some glass runners on this I could then have sliding glass doors. Then on the top more runners with a space above with mesh for ventilation. I am trying to work out if sliding doors would work as the whole width is only 12 inches, so I would have very narrow doors. Perhaps try to hinge a glass door in some way?

I've never done this kind of thing before and wonder if I am going into the realms of fantasy with this idea!

The size of the tank would be just ideal for a vertical, jungle type habitat though.

I would really welcome your input on this, thank you.
