Nonindigenous Occurrences:
Unconfirmed report of breeding population in the Everglades, Florida, prior to about 1940 (Myers 1940). Based on extensive sampling during the 1970s, established populations, if ever present, no longer exist (Courtenay and Hensley 1979; Courtenay and Stauffer 1990). Collected in Lake Worth Drainage District canal L-15, west of Atlantis and Lantana, adjacent to a fish farm in Palm Beach County, in 1969 and 1970 (Ogilvie 1969; Courtenay et al. 1974), but species not found in subsequent surveys (Courtenay and Hensley 1979a). Several specimens were taken from a marsh in Orleans Parish, Louisiana, in March 1997 (Cashner, personal communication).

† Populations may not be currently present.
Means of Introduction: The Florida records probably result of aquarium releases or escapes from fish farms. Louisiana records are probably aquarium releases.
Status: There is no recent evidence of a breeding population in the Florida Everglades; more recent reports of fish represent non-established populations (Courtenay and Hensley 1979; Courtenay and Stauffer 1990). Reported from Louisiana but status is uncertain.
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.
