Female Red Tuxedo Lyretail Swordtail.

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 […]

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 […]

Red Freckled Hifin Swordtail

Photo: A first generation Red Freckled Hifin Swordtail male in front of one inch grid to show size. Okay, it’s going to take a while to untangle the genealogy of this fish. 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 […]

Giant Redtail Blue Variatus Update

Photo: Our breeding male Giant Redtail Blue Variatus and one of his females. The two smaller fish are mature Redtail Blue Variatus. A while back I wrote about a new strain of fish we were developing (see: http://goliadfarms.com/giant-redtail-blue-variatus/). This blog gives a mixed bag of updates. The Giant Redtail Blue Variatus, as its name indicates, […]

Sunset Variatus

Photo: Male Sunset Variatus I’ve recently begun blogging about the Variatus-type Platies we raise. For a discussion about the meaning of “Variatus-type,” check out an earlier blog I wrote about our Redtail Blue Variatus. This blog concerns our Sunset Variatus strain, which we developed independently to but is visibly identical to the commercially available Sunset […]

Redtail Blue Variatus

Photo: A very nice male Redtail Blue Variatus either challenging another male or displaying for a female. We raise a variety of Variatus-type Platies. I say “Variatus-type” because while they look like Xiphophorus variatus (Variegated Platy), they are commercial strains and might have genes from other Xiphophorus species such as X. hellerii (Green Swordtail) and […]

Giant Redtail Blue Variatus

Photo: Pair of Giant Redtail Blue Variatus and male regular Redtail Blue Variatus Xiphophorus species, which include swordtails, maculatus platies, and variatus platies, hybridize readily. A while back I wrote, when I was writing for Tropical Fish Hobbyist magazine, an article about some hybrids I had been working with. This blog provides an update on […]

Flame Variatus Male

Flame Variatus

The first photo is of a male Flame Variatus and the second of a female. This is a commercial (domestic) strain of Xiphophorus variatus. Like most commercial xiphophorines (swordtails, platies, and variatus), this fish is likely to be of hybrid origin, although the strain clearly is primarily X. variatus based on its fins and shape. […]

Redtail Blue Tuxedo Variatus Male

Redtail Blue Tuxedo Variatus

The photo is of a male Redtail Blue Tuxedo Variatus, a commercial (domestic, if you prefer) strain of Xiphophorus variatus. Like most commercial xiphophorines (swordtails, platies, and variatus), this fish is likely to be of hybrid origin, although the strain clearly is primarily X. variatus based on its fins and shape. In a previous blog, […]

Redtail Black Variatus Male

Redtail Black Variatus

The photo is of a male Redtail Black Variatus, a commercial (domestic, if you prefer) strain of Xiphophorus variatus. Like most commercial xiphophorines (swordtails, platies, and variatus), this fish is likely to be of hybrid origin, although the strain clearly is primarily X. variatus based on its fins and shape. We acquired our first variatus […]
