Open stretches of permanent water or riverine pools with gently sloping sandbanks for resting. The area should contain enough food. Prefers pools that are deep enough for submersion, with slow running water. Moves away during floods, but return to the same pools unless these have changed too much.
Grasses at night and rests during the day, half-submerged or on a sand bank if it is not too hot. Sometimes grazes far from water, especially during dry periods. Makes use of the same route frequently and leaves a double-track game path. Gregarious. Herds of between 10 to 15 animals.
