Dither fish

[TheFishDodo]

Not sure where to post this question so ill do it here. I decided to get a pair of Andinoacara Biseriatus in a 20 long but I want/need some dither fish for them but I have no idea what type of fish I should get. I was thinking Emperor Tetras because they come from the same tributary but there might be a better option so if anyone has any ideas please post them bellow.

Tetras would be geographically correct.
And if you want to be really geographically correct, they are found in the Rio Condoto, Rio San Juan river systems in Colombia west of the Andes.
So Colombian and other tetras found west side of the Andes would be perfect as dithers.
Above and below, a river in Colombia I visited last year.

Looks like a beautiful place I narrowed it down to 2 fish the spotted hatchet and the emperor tetra.
