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.
