20g long vertical build?

[SwimminSteve]

Hi folks. I have a spare 20 gallon long that is not only taking up space in my living room, but also tempting me to fill it will new critters . I really don't space to set it up unless I use it vertically.
So I have some questions.
Is there a kit or instructions to convert this size tank?
Has anyone ever converted a 20gal long into two vertical 10 gallons? Does that make sense?
Would a WTF be happy in a vertical 20g long? If not I would probably split it half and house pacmans.
I have ACFs, GABF, and a Pacman right now. I've never had an arboreal species so I appreciate the help!!
Suggestions are welcome. And if this sounds like a horrendous idea, feel free to set me straight .
Thanks!
