I have searched to see if there already was something posted on this, and have tried searching the web, but with no success. This could definitely be caused by user error

I recently got some archer fish that I am going to slowly get into a brackish set up, as they were being kept/sold as fresh water. I also want to keep the tank as close to their natural environment/habit needs, including overhanging plant life and something that would hold crickets so they can shoot them down.
SO!!!
I am looking to make/purchase a sort of mesh terrarium topper type thing for a standard 75/90 gallon tank. However, I can only find small ones 10-29gal). Ive got some ideas in my head if I have to make it myself, but I wanted some expert opinions!
Are there any sites that currently sell something like this?
OR
What, in your opinion, would be the BEST *and relatively cheap* way to construct this on my own?
I look forward to hearing what some of yall have done and/or think about this!!
**** I'm thinking not just a screen cover, but something that could give 10-15'' extra height to the tank, and sit on the top/attach somehow...
