Poecilia sphenops, called the short-finned molly or common molly, is a poeciliid fish inhabiting freshwater streams, coastal brackish, and marine waters from Mexico to Colombia. 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. Females of the species prefer an external temperature of 29°C year round, whereas males prefer an external temperature of 29.6°C in the winter, and 25.5°C in the summer.[3] This species of fish is seen to 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.[4]
Standard size of male fish is 3.2″ (8 cm) and female fish is 4.8″ (12 cm).
