Nijsseni, Panduro, or Agassizii

[Seisage]

I'm working on an Ucayali River biotope community tank and had been planning on putting an agassizii in it. However, I realized that I honestly hadn't really considered two of the other options I have: nijsseni or panduro. My parameters are appropriate for all three of them and I like the way all of them look (nijsseni a little less than the others though), so I'd like to ask about peoples' experiences keeping these species. Is there one you'd recommend over the others, or one that you just like better for whatever reason? The tank is 25gal, 30"x12" footprint, if that's helpful at all.
