Hello!
I took some pics from one of my smaller tanks: Here I made a back-wall-covering from styrofoam that was cut in form of a stone wall.
A small snake can climb using the "joints" between the "bricks" or climb over the braches I attached on the walls (somewhere you can see pieces of hot-melt adhesive, I'm sorry about it, Pietro just decided to "remove" some of the decoration :crazy02: )
I also made some platforms from styrofoam, when I put a piece of cork on it my snake loves to lie there.
The last pic shows another tank in the "pure styrofoam"-phase
The (rough) steps to make such a back-wall:
You need:
- sheets of styrofoam/polystyrene, about 2-4cm thick
- glue (to be used with styrofoam, so must be solvent-free)
- water-resistant plaster, tile adhesive ore alike
- clear laquer/varnish (solvent-free/childproof)
- acrylic colors (solvent-free)
1. Cut a piece of styrofoam of the size of the back wall of your tank. On this piece the background-structures etc. will be glued.
2. Cut the rest of styrofoam into the structures you want on the back-wall-covering, this could be "bricks", "rock-structures", "trees" or whatever you like.
3. Glue the structures on the wall-sized piece of styrofoam.
4. When everything dried, mix the plaster and brush it onto the whole construction. You may need some layers (3-5) until the surface is solid enough.
5. Now you can paint the back-wall-covering as you like, in my case I used light brown to imitate freestone (the frilled lizard is a bonus

)
6. Then paint the whole surface with the solvent-free varnish.
7. Finally glue the piece into your tank - it's important to do this because otherwise it wouldn't be safe for your snake to climb on. Be sure the piece fits tight, small snakes will love to crawl
behind it
Note: Steps 4-6 refer to all surfaces on the construction that are visible/have contact to your snake. If you glue it to the back wall of your tank you don't have to care about the backside of the styrofoam as no one will see it or no-snake will touch it
I hope this gives you some ideas about it, you have fantastic possibilities to create a tank both enjoyable for you and your snake
