Sanke Swordtail
This swordtail variety has spectacular tri-coloration just like its namesake koi!
The Koi Sanke Swordtail (Xiphophorus helleri) is a rather uncommon and very colorful swordtail variation that has ample orange, black, and white/silver koi-like coloration. As is typical with swordtails, males often have a long "sword" extension at the bottom of the tail, although some females can also develop a sword. Reliable sexing can be done by checking the a**l fin area for the male gonopodium, a tube-like organ used in fertilization during spawning. Like most swordtail varieties, the Koi Sanke Swordtail is a variant of the wild Green Swordtail (Xiphophorus helleri), but it also has genetics of other Xiphophorus species (such as X. maculatus and X. variatus platy varieties) to achieve new color patterns
