Biotope Video: Blackwater Shallows
in the Middle Rio Negro
A blackwater habitat like this one is characteristic of the middle Rio Negro and home to Cardinal Tetras and many other species in the tropical fish trade.

The Igarapé at Daracua, which I profiled in detail in the
Jan/Feb 2017 issue of
, is closer to what most people imagine when they think of the warm, tannin-stained waters of many Amazon tributaries. It immediately offers inspirations for my future biotope aquarium aquascaping plans.
Here, in the shallows of a small area of flooded forest not far from the city of Barcelos, dozens of familiar species of aquarium fish can be found living among the tangle of roots and fallen branches. Perhaps the most recognizable of these-the Cardinal Tetra (
) takes center stage through much of this video, its unmistakable neon blues and reds contrasting strongly against the tea-colored water.
