Poecilia sphenops, called the Mexican molly or simply the molly, is a species of poeciliid fish from Central America. It was once understood as a widespread species with numerous local variants ranging from Mexico to Venezuela, but these variants are today considered distinct species belonging to the P. sphenops complex and P. sphenops itself as being native to Mexico, Guatemala, and Honduras.
The fish lives in tropical freshwater and brackish water habitats. [2] The shortfin molly is considered benthopelagic. [2] It lives in a pH range between 7.0 and 7.5 at temperatures between 22 and 28 degrees Celsius. [2] The species does not migrate. [2] It is an invasive species in the Muddy River of Nevada, USA.

A brackish-water aquarium is an aquarium where the water is brackish ... for example mollies, ... and the temperature is usually in the tropical range of 76-82 °F.
Poecilia is a genus of fishes in the family Poeciliidae of the order Cyprinodontiformes. [2] These livebearers are native to fresh, brackish and salt water in the Americas, and some species in the genus are euryhaline.
The sailfin molly is a tolerant species, as it can exploit the thin film of oxygen-rich surface water with its upturned mouth, so is able to survive oxygen-depleted habitats. A euryhaline species, the sailfin molly may be found in a variety of saline environments, tolerating salinities as high as 87 ppt [10] and breeding in brackish waters.
All guppies and mollies are hardy fish that tolerate lower oxygen levels and temperatures than most aquarium fish, give birth to live young, and readily breed in home tanks. [ 58 ] can live in full sea water [ 59 ]
Poecilia gillii is a livebearer, meaning that females give birth to live fry. [3] It reproduces continuously year-round, with most juveniles appearing in August. [2]In some poeciliid species, e.g. P. latipinna and Xiphophorus multilineatus, large males court females while small males instead rely on chasing and sneaking up on the females to copulate.
The wide variability in maturity dates and brood sizes is a result of genetic heritage, varying temperatures, and food availability. They become sexually mature faster and produce larger broods in warm (approximately 27 °C or 80 °F) water that provides an overabundance of food. [28]
