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.

Mollies rank as one of the most popular feeder fish due to high growth rate, birth size, reproduction, and brood number.

Biology

Mollies are similar in appearance to their livebearer cousins, the platy, swordtail and guppies; the molly tends to be slightly larger and more energetic. Many aquarists note the stronger individuality and aggression in keeping mollies versus platies, who appear much more docile.

Size

Standard size of male fish is 3.2″ (8 cm) and female fish is 4.8″ (12 cm).
