| Notas | Once widely distributed and abundant now restricted to temperate upper reaches of distribution range and in 1971 was considered a seriously threatened species. Siltation is the apparent cause of this decline. Juveniles are zooplanktivores, ingesting water fleas, rotifers and water mites with a sucking action. Peaceful community fish. |
