The Rio Negro Piranha, often identified as Serrasalmus rhombeus, is a large and highly predatory freshwater fish native to the Amazon Basin, particularly the Rio Negro. Known for its powerful jaws and sharp teeth, it is a solitary and aggressive species that requires a very large aquarium. Its coloration can vary from silvery to dark grey, often with iridescent scales and faint spotting.
