Botos live mainly in dark, cloudy water. They seem to prefer areas where water currents meet and cause turbulence. Several studies have found that they are attracted to places where streams flow into the main river channel or to areas around sand bars or sharp bends in the river. Botos live in water with temperatures ranging from about 73 to 86°F (23 to 30°C). During the rainy season (November to May) when rivers flood, they move out of the main river channel into the shallow flooded forests. As the waters go down, they move back into the deeper main channels.
