The Cuban gambusia, spotted gambusia or blue gambusia (Gambusia punctata)[2] is a species of freshwaterfish. It is a member of the familyPoeciliidae of orderCyprinodontiformes, and is the type species of its genus.[3] It is native to Cuba, inhabiting lakes, ponds and streams, including mountain streams. A carnivorous surface feeder, it occurs in shoals near the shoreline. It be found in estuarine habitat.[1][4]
This species has the terminal, upward-facing mouth typical of surface feeders, and a protruding belly. It has four or five rows of darkly spotted scales, possibly forming a dark lateral stripe in the case of the midline row. The dorsal and caudal fins are typically partially spotted.[4]Males reach a maximum standard length (SL) of around 4.8 cm, with females reaching about 7.0 cm.[5] Record SL for this species is 10 cm.[1]
