Bichir biotype help

[Nyrkorey]

So as you know I rescued a couple bichir from someone who was taking horrible care of them. Luckily they are all doing amazing and the bloat issue has been resolved with better water quality!
I wanna give them a nice home I have a open 135. I wanna create a biotype tank for them. But I'm not up to speed on the type of fish that would he considered biotype for them?
If anyone can help that be awesome and as for how many of those different species I could do in a 135.. 6 foot long.

What type of bichir and how many? Most originate from the rivers around Africa so maybe congo tetras and the like?

Id scape it with tons of rocks and driftwood, epiphyte plants like bolbitis, Anubias and maybe background plants like apogeneton. Might not be exactly what its like in nature but would look dope!
