What to do with tank?

[monkeytreey]

Hello,
New to the forums and to Terrarium construction, so far I have built a few different types crossfire for a beardie and a 10 gallon vert. I like making these as a hobby and have started to collect stuff to make more that will be sold in my area for cost of materials. One of the tanks I have obtained is somewhere between 20 and 40 gallons (longer and taller than 20 long not as deep as a 40 breeder) I will get around to measuring it soon and can clarify. Anyway the previous owner painted the outside of the “back” and installed and siliconed a bulkhead in the back. I am mainly looking for ideas on what to do with it. My main idea is to add some plumbing hidden behind a background for a fogger but should I do the tank vert (background on side and back) or leave it horizontal (background on back only). Since I won’t be keeping the terrarium I thought I would see what others think before I start working.
Thanks
