How to breed mollies easily

Yes.
Normaly I never would recommend medication without diagnosis, but with livebearers and worms I make an exception. They are just too common.


The big sail fins are P. velifera, P. kykesis and P. latipinna. They are way harder to keep and to breed in prolific numbers than the other Mollies. They tend to fall ill quickly and to show dwarfism and other genetic problems after only a few generations. Sometimes the F3 is already heavily affected. Them getting sick often is also somehow the reason for many people believing mollies need salt. Though they can live in pure freshwater habitats in nature, they often seem to do better with salt in the aquarium. Which prevents the outbreak of some diseases and makes them grow better but also tends to decrease their lifespan.

I have velifera and latipinna and can’ t stop them from breeding on the other have a really nice strain of black mollys for months and still waiting on fry. I’ve found the aquarium strains to be weak..

I have F4 sailfin molly from one parents. They breed every couple months if you use trap to keep the fly from getting eaten. But their life expectancy is short, rarely exceeding 2 year. I am trying now to cross female black molly with the only surviving F4 male sailfin.

I'm very curious.
Are they wild caught? Are they pure strains? Do you have pictures?
