Adult animals are found in floodplain forests of both white water and black water rivers . In the vicinity of Manaus, for example, schools of different species meet that migrated down the Rio Negro to spawn in the Amazon in December and January. A time when the water level rises. Similar behavior was observed in other Brycon species in the Rio Madeira . The embryos and larvae develop as they drift downstream the Amazon. They are washed into the flood forests of the white water rivers. After the spawning season from February to March, the adults return to their original blackwater river habitat. Later in the year, between May and August, the fish return from the nutrient-poor Rio Negro and other tributaries to the Amazon or Rio Madeira, where they stay until the end of the rainy season in September. They then migrate back upstream into nutrient-poor tributaries and forest rivers, where they spend the dry season until the next spawning season. Vegetable material plays a huge role in their diet. They spread numerous plant seeds.
