Thought I'd add some videos/pictures and share some species I saw while netting at night. I'll keep it (fairly) small, 25 cm or less.
First off, some small Platydoras Armatus foraging around.
Next, Piabucus Melanostoma. I found it striking, and took a picture even when I left some relatively "prettier" and widely known species undocumented, such as Serrapinus Kriegi or Aphyocharax Anisitsi.
Some sort of pleco, hard to tell which. Could be Hypostomus Luteomaculatus, small, or Uruguaiensis, dunno.
Characidium Zebra, juveniles (confirmed this with an ichthyologist just to be sure) Also caught a full grown one but sadly did not snap a pic of it.
Already shown, all the Otocinclus sp., likely Vestitus, absolutely swarming the place. In the first video you can see one as well, towards the end.
Last, and perhaps the one I liked the most, Leporinus Striatus. This species grows to about 25 cm, and I did not take a picture. These are off the internet. IMO, they do not do the blood-red snout justice. It's barely perceptible, but really striking in person.
There's tons of fish I haven't mentioned. Rineloricaria is perhaps the oddest, although I find them pretty distasteful for some reason.
I'll do this again sometime this year, but closer to Buenos Aires, this is a 1000 km trip and can't be done too frequently. If it happens, It'll be more cichlid-heavy, and I'll do my best to document it more thoroughly. Here are some shoreline pics. You can see how an aquarium could be made to mimic these roots, as the river was very very low these days, but this is all usually underwater.
