Well, there are several green swordtails (both fancy and wild strains). But in general we call them green without being them really green. Just like with Xiphophorus pygmaeus (one of the dwarf swordtail strains). there are 2 colors available: Golden and blue. The golden actually does have a golden colored body. But the blue ain't blue but variations of brown. With both golden and blue strain, the females are also the socalled blue variation. With the golden dwarf swordtail, just the male does have this particular golden coloration.
But back to the green color. I do keep the Xiphophorus alvarezi (wild strain of swordtail) and depending on it's location of collection, the coloration may differ. Mines are green (specifically the males show more green in comparison to a female). The alpha males will show the best intensity of green.
It's a beautiful wild green swordtail and prolific for sure.

Above: two developing males which turn green already.

Young males do look like females and just like the females, they have multiple lateral lines on both sides of the body. But once the male characteristiscs are showing, most of those lateral lines will fade and the middle lateral line will become dominant in appearance.

Beautiful! Is the sword as yellow as it appears in these pictures? The contrast is striking.
