† Populations may not be currently present.
Means of Introduction: The Hillsborough County, Florida, introductions were probably due to releases or escapes from local fish farms. The Nevada introduction likely represents the result of an aquarium release.
Status: Failed in Florida and Nevada.
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.
