Comments: Adults inhabit creeks and rivers, usually in cool, clear waters over gravel bottoms in sections alternating between pools and rapids.  Usually found in clear, moderate to fast-flowing water in the upper reaches of rivers (sometimes to altitudes above 1000 meters).  Often forming aggregations below barriers to upstream movement.  Timid species that forms fast-moving shoals (Ref. 44894).  Often form large schools especially prior to spawning.  Feed on small crustaceans, insects and their larvae and algae.  The intestinal tract is long, s specialization to assist in the breakdown of ingested plant material (Ref. 44894).  Spawn:  Feb.-May; 25,000-68,000 eggs which sink to bottom downstream of spawning site.  Hatching:  10-20 days; larvae, 6-7 mm TL, swept downstream to estuaries and the sea, return to freshwater after 6 months.
