Fancy Red Tuxedo Swordtails

Photo: Female Red Tuxedo Lyretail Swordtail. As is typical of our strain, females don’t have as bright red coloration as males. We’ve started working on adding three fancy fin types, lyretail, hifin, and plumetail to each of our commercial swordtail, maculatus, and variatus lines. I’m going to use our Red Tuxedo Swords to demonstrate how […]

Photo above is a male Orange Freckled Swordtail. The grid behind him is in inches and shows his size.

Introducing a Dominant Gene

Photo: A male Hifin Redwag Swordtail. I’m beginning a blog series on introducing new genes (technically alleles, but I’ll bow to common usage) into a xiphophorine population. In this blog I’ll discuss the mechanics of introducing a single dominant gene into a xiphophorine population. By the way, this doesn’t only apply to xiphophorines or even […]

Let’s take the female first. The pictured female is large. She’s in front of a one-inch grid that shows she almost four inches […]
