Poecilia sphenops, called the molly[1][2] or Mexican molly,[2] is a poeciliid fish inhabiting freshwater streams and coastal brackish waters from Mexico to El Salvador and Honduras[1] to Colombia.[2] The wild-type fishes are dull, silvery in color. The molly can produce fertile hybrids with many Poecilia species, most importantly the sailfin molly. The male mollies generally tend to be mildly aggressive. They have a minimum lethal external temperature of 10.8–11.8°C, and a maximum lethal external temperature of 38.8–39.5°C when acclimated in a range of 20–35°C.[3]
