At least three species of mollies are the parent species of the numerous breeding forms that exist of these fish today: Poecilia sphenops, P. latipinna, and P. velifera. Possibly P. mexicana was also involved, but this is unclear, as this species was long considered a synonym of P. sphenops.
Some color and fin characteristics could only be established in the strains through species crosses, but others occur naturally in wild mollies. These include the gene for black coloration, which is found in many natural populations of all four species mentioned. In its maximum expression it leads to the so-called Black Molly.
Very popular at present are the black speckled mollies, which are called “Dalmatians” after the dog race. In the wild, only one black speckled specimen occurs among thousands of normally colored animals, but the color morph, being inherited on only one allele and in both sexes, can be well established in selection breeding (when a morph is inherited from several alleles, possibly even on different chromosomes, breeding becomes complicated).
The largest of the Dalmatian mollies is the sailfin molly – and the most beautiful!
