Disclaimer:

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.

Ecology: Found in creeks, lakes and rivers, preferring a sandy or muddy bottom covered with detritus (i.e., dead leaves and wood). Nocturnal omnivore, foraging for small fishes, crustaceans, zooplankton, and insects (Burgess 1989; Boujard et al 1997; Le Bail et al. 2000).

Means of Introduction: Probable aquarium release.

Status: Failed in Florida: a single individual was the only specimen ever reported.

Remarks: The Florida specimen was tentatively identified as R. quelen based on information from Silfvergrip (1996). Several members of the genus Rhamdia are found in the ornamental fish trade (Burgess 1989). Voucher specimen: Florida (UF 103762).
