Importance To Humans
The sailfin molly, in its many colour varieties, is of considerable interest and value to aquarists, and many artificially selected varieties are produced and sold in pet shops. Wild-type sailfin mollies are also bred as feeder fish for larger carnivorous fish. Naturally occurring populations of sailfin mollies help to control mosquito populations by feeding on the larvae and pupae of these pests. As noted above, they may not be suitable as a biological control agent in many cases, as they can easily become an invasive species, or even a pest themselves.

Famous quotes containing the words importance and/or humans:
“There are secret articles in our treaties with the gods, of more importance than all the rest, which the historian can never know.”
—Henry David Thoreau (1817–1862)
“Because humans are not alone in exhibiting such behavior—bees stockpile royal jelly, birds feather their nests, mice shred paper—it’s possible that a pregnant woman who scrubs her house from floor to ceiling [just before her baby is born] is responding to a biological imperative . . . . Of course there are those who believe that . . . the burst of energy that propels a pregnant woman to clean her house is a perfectly natural response to their mother’s impending visit.”
—Mary Arrigo (20th century)
