Biology: |
Gregarious and frequents stagnant waters of lakes and reservoirs, rivers and canals with calm waters. Feeds on small benthic invertebrates, insect larvae and plants. Juveniles feed on zooplankton. Reproduction takes place in May to July. Exhibit polyandry. Of little interest to game fishers and consumers (Ref. 30578). Unpopular with commercial fishers due to its small size and competition with more desired species.
