The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

† Populations may not be currently present.

Ecology: Rosy barbs are omnivorous, consuming a wide and varied diet including eggs and fry of conspecifics and other species (Sterba 1966; Malhotra and Gupta 1990).

Means of Introduction: Probable escape or release from fish farm, or aquarium release.

Status: Failed in Florida and Louisiana; established in Puerto Rico.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.

Remarks: This species is an important ornamental fish (Talwar and Jhingran 1992).

Voucher specimens exist for Puerto Rico (NCSM 45882, 45893; USNM 386191).
