I ran across a really cool video today showing several species of fish from the Araguaia river in Brazil. The short video by Oliver Lucanus is Part 2 of a video set he made about the Araguaia in Brazil. This was taken after recent rains had flooded the upper Araguaia and includes a possibly unidentified dwarf species of Crenicichla, which Oliver posits is from the Regani group. I also encourage you to watch the Part 1 video for more information about this river drainage in Brazil.
In the video above, you’ll see a small group of the dwarf pikes show up at about the 44 second mark. Oliver narrates the video and provides a nice description of these dwarves.
For more information about Oliver, check out the interview I did with him back in January of this year.
