What are the different kinds of molly fish?

There are hundreds of "sports" that unscrupulous people have given names to like "Dalmation" "Lyretail" etc. There are actually only three types of molly. Mollies were once classified as "Mollienesia" but the taxonomists have now placed the Molly into the same classification/genera as the Guppy and they are now classified as "Poecilia". The three species are P. velifera, P. latipinna and P. sphenops.
