† Populations may not be currently present.
Ecology: Inhabits shallow, vegetated nearshore areas in lakes, and adjacent streams or rivers (Konings 1990; Eccles 1992). Consumes a variety of prey, including benthic invertebrates, algae, and small fishes (Konings 1990).
Means of Introduction: Likely aquarium release.
Status: Unknown. Persistence over ~10 years and variable catch rates among years indicates that this species has reproduced (Shafland et al. 2008). However, a lack of reported specimens since 2007 suggests that this species may be extirpated from Florida.
Impact of Introduction: Unknown. Could potentially compete with co-occurring native fishes for food; however, its relatively small size makes this species a potential prey item for larger piscivorous fishes.
