Comment by the expert

Roberto Reis: Very short description of the BIN, no videos, no photos. Describes a black water environment but map shows a white water, big river.

Francesco Denitto: Few information on BIN (also because the participant does not describe a specific biotope).

Donald C. Taphorn: You needed to include more basic information about the habitat and fishes, and list informative websites.
