Besides Sanshoku Swordtails there is also Showa swordtails you can find these on the internet too! Which tend not to cost as much as Sanshoku Swordtails on the internet. However they are not really all that expensive unless you are talking breeder stock that are have a certain percentage base in being pure bred strains.
Genetics take time to understand in Livebearers and I don't think that many will have an explicit answer in the development of Snashoku Swordtails however I would think that Painted Swordtails strain was involved in a cross with Koi Swordtails to develope the Snashoku Swordtail and with selective linebreeding the developer developed the line that you are referring to.
It takes many years of dedication and seperation of males and females, with several tanks to develope strains to be purebreeding in livebearers.
A good club to belong to for reference is the American Livebearer Association. They may have some detailed information available in the development of the strain your refering to. American Livebearer Association
The American Livebearer Association actually has their annual show coming up in Cleveland this year where many exotic domestic and wild type livebearers will be on display and possibly in their auction.
Just to let you know the Pet Shop that I work at in Canada can order all three swordtails involved in this discussion but we do not offer internet sales. So they really are not that expensive. However if you are thinking about getting pure strains often it is best to deal with a breeder of the strains that you are wanting.
On a personal note I do know of a breeder in the United States that sells this strain in Hi Fin Lyretail so I am thinking this is why you think they are expensive as a whole but that strain breeds pure. American Livebearer Association
