I get it now! Kinda like 55g only taller, cool. I'd get harlequin rasboras or maybe just a ton more dwarf rainbows or more CPDs, instead of red-eye tetras; their teeth (unlike rasboras, CPDs & rainbows) are much toward the front of their mouths (like pirhanas) & can "nip" most any fish or shrimp.
On my 55g "riverish" tank I have 2 AC 70s & a powerhead. On my 75g I have a Fluval 404 & AC 70.
As for plants, it depends on your lighting. Some are almost fool-proof: java fern, java moss, anubias tied or glued to wood or rocks. & most cryptocorynes planted in almost any susbstrate. Those are very easy & a good starting point. Tare a few more that "may" work too.
