What Kind Of Fish Do You Suggest Into My Nano Tank? Make It A Pair, Pl

[Renahastetras]

Live and learn. We had beautiful tetras and as I mentioned before all the water data and the fish were fine. Feeling great! Someone mentioned even if they are look fine they are not. Tetras must be in group!!  Sure..Whatever! - ours are fine! (( We paid the price.... I'm really upset abot this.
So my question is what kind of fish do you suggest that would be fine in a Nano tank, 5 G, so close to 20 L. Please, suggest fish that I can have a pair of and no bettas.
