Sorry, but those are trade names for body shapes, they are not species names (as pointed out above). Either give a scientific name or a common name which is used exclusivity for one species (like "goldfish", for example). If the origin of these fish was a generic LFS "molly" (regardless if they were then bred by someone), they are most likely hybrids and you don't actually know what they are.
Poecilia Sphenops and Poecilia Latipinna.
Any better? If you had said you wanted scientific names before I could have given them straight away.
