==Biology==
During the early stages of its lifecycle, it eats mainly zooplankton, but as it grows, it eats more and more phytoplankton, and as a juvenile or adult is a herbivorous column feeder, eating mainly phytoplankton and submerged vegetation. It has modified, thin hair-like gill rakers, suggesting that it feeds by sieving the water.
It is diurnal and generally solitary. It reaches sexual maturity between two and five years. In nature, it spawns in the marginal areas of flooded rivers.
