Overhere some pics of the combination Yucatan swords (Xiphophorus hellerii Yucatan) & Poecilia mexicana...
The more dominant the male becomes the more red will be developed on his body. They are born being green swordtails. The red starts from the bottom. So, complete dominant males will develop a total red body color but again they start off as being green ones.
Poecilia mexicana is a wild molly species that can differ in color depending on the location in free nature. But most are greyish.
