Where did you find the pictures?

From some underwater video.
2nd one looks like a roseline shark but it's not. these are all from the same region brasil- lago grande.

The 2nd looks to be one of the Prochilodus genus.
The 3rd looks like they are pencil fish.
1 is a tetra, maybe head and tail light.
But none of the above are in my identification comfort zone.
