Depending upon environmental conditions, sailfin mollies may become reproductive in less than a year.

Sailfin mollies are members of the lower end of the food chain.

Sailfin mollies are small fish.

Good tankmates are swordtails and sailfin mollies.

Wild-type sailfin mollies are also bred as feeder fish for larger carnivorous fish.

Most studies have focused on females, but male mate copying has been found in sailfin mollies (Poecilia latipinna).

The natural lifespan of sailfin mollies is short, particularly in the case of the males, which may live less than a year after achieving sexual maturity.

I too have lost fish - two Sailfin Mollies, three guppies and a Scissortail (which committed suicide, unnoticed when I took the cover off the tank).

Sailfin mollies introduced to California have caused a decline in populations of the federally protected and endangered Desert Pupfish (Cyprinodon macularius).

Full-grown fish are usually larger than 10 cm (4 in) and large females can reach almost twice this length, though especially captive-bred individuals grow only to the size of sailfin mollies.

Sailfin mollies are most commonly observed as the shallow surface waters along the edges of marshes, lowland streams, ponds, swamps, estuaries and even ephemeral water bodies such as roadside ditches.

I used to have breeding pair of Sailfin Mollies, and on the two occasions that fry were produced, I had no real problem from the Glassfish trying to eat them, in fact the Diamond Tetras were more troublesome!

Poecilia latipinna (Sailfin molly)

The sailfin molly, Poecilia latipinna, is a species of fish, of the genus Poecilia.

The guppy has been successfully hybridised with various species of molly (Poecilia latipinna or velifera), e.g., male guppy and female molly.

English: Yucatan molly, sailfin molly (though this name is often used for Poecilia latipinna as well as the commercially produced hybrids kept by fishkeepers)

Other species considered similar to G. affinis include Poecilia latipinna, Poecilia reticulata, and Xiphophorus maculatus; it is commonly misidentified as the eastern mosquitofish.
