Just Curious, What Could Have Went Into The 76L If I Didn't Have M

Oops title got cut. -> If I didn't have my current ones to live there.
I keep seeing stocking lists for different sized aquariums, so just wanted to know out of curiosity, not up for different types of fish (at least not this year, I already have 3 that are more or less not entirely suitable for it but they'll be the only ones living there).

Tank dimensions: 85x30x30 (LxWxH), 76.5L (20+ gallon).

So what could have lived in it:
a) Ideally (shoaling + non-shoaling or just shoaling)

b) Non-shoaling fish, the kind with an individual personality.

If you didn't haves your fish in there you could easily have

8 ember tetras
10 Pygmy cories
1 honey gourami or sparkling gourami

That being the ideal.

But what about a setup with no shoaling?

A pair of Betta imbellis, german blue rams, or shell dwelling cichlids

Hmm, doesn't sound like much.
What about the usual fish such as guppies / platys?

 

[Fishy friend2]

you could easily have a slightly small breeding colony of them in there. Just remove the fry as they start t over populate the tank

And what about hoplos, I've read that they can be housed in 20 gal tanks, but what species? I don't even know what species mine is, but he's 13 cm or so long at his age. Unless he's been dwarfed or something. But he doesn't look like a Megalechis Thoracatum except for his spots. I've seen Magdalene having those pointy fins, but they don't have any spots.
And how common is the dwarf hoplo in sales? I've heard they don't grow more than 10 cm.
