† Populations may not be currently present.
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.
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.
