Comments: The fry and juveniles of <i>Distichodus antonii</i> live in aquatic prairies and in plant fringes; adults feed in <i>Echinochloa</i> patches and live at the edge of streams along islands and even on the bottom in the middle of the stream (Ref. 96324). The species is a phytophagous species; stomachs almost always contain plant fragments, with easily recognizable twigs and leaves of <i>Echinochloa</i>, which comprises the largest part of their diet (Ref. 96324). It has two annual periods of reproduction and spawning and egg deposition have to take place at the border of the stream, just before the flood. Maximum reported total length is 550 mm (Ref. 1878), although it is stated it can reach a size of more than 800 mm (Ref. 7094, 96324). Maximum weight was recorded at nearly 10 kg (Ref. 7094).
