Comments: Found along shore over sandy substrates in the mainstream of rivers, as well as tributaries with flow.  The water is tea-colored with transparency usually moderate to high, pH usually around neutral (6.07-7.06), and high oxygen concentration (5.7 mg/l- 7.1 mg/l) as well as oxygen saturation (50.5% - 90.5%).  Occurs sympatrically with <i>Bryconamericus alpha</i>, <i>Bryconamericus cismontanus</i> and <i>Bryconamericus loisae</b> (Ref. 86277).
