Identification: For distinguishing characteristics and figure, see Smith (1945) and Page and Burr (1991); distinguishing characteristics were also given by Kottelat et al. (1993). Color photographs provided in Axelrod et al. (1985) and Kottelat et al. (1993).
Size: 4-7 cm SL.
Native Range: Tropical Asia. Widely distributed in southeast Asia including Thailand, southern Vietnam, Malay Peninsula, Sumatra, Java, and Borneo (Sterba 1973; Axelrod et al. 1985; Rainboth 1996).

A population was established in a small area (canal system) on the south side of Lake Worth Drainage District canal L-36 in Delray Beach, Palm Beach County, Florida, since the late 1970s (Courtenay and Hensley 1979a; Lee et al. 1980 et seq.; Courtenay et al. 1986; Courtenay and Stauffer 1990; Page and Burr 1991; museum specimens). Additional collections were made in 1992 (museum specimens). Although considered extirpated (Shafland et al. 2008a, b), recent collections (2012) have been made on the east side of Loxahatchee National Wildlife Refuge (Schofield and Pecora 2013).

† Populations may not be currently present.
Ecology: Found in shallow sluggish or standing-water habitats with a lot of vegetation. Feeds on zooplankton, crustaceans and insect larvae.
Means of Introduction: Probable escape from a nearby aquarium fish farm (Courtenay et al. 1986; Courtenay and Stauffer 1990), or possible aquarium release (Courtenay and Hensley 1979; Lee et al. 1980 et seq.).
Status: Locally established in Palm Beach County, Florida, from at least the late 1970s (Lee et al. 1980 et seq., Courtenay and Stauffer 1990). Thought to be extirpated (Shafland et al. 2008a, b); however, recent collections (October 2012-July 2014) reveal it is in fact established (Schofield and Pecora 2013).
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.
