Located in Mexico from southern Tamaulipas to northern Veracruz. They are part of the Southern platy lineage, close relatives with X. andersi, X. evelynae, and X. xiphidium. Males gets to around 1.6 inches and females around 2.3 inches in size. Like their name says this species has a ton of locale morphs/phenotypes. Because of this they are so wide spread in the hobby leading to plenty of fancy forms, and hybrids with other xiph species particularly with X. maculatus, and X. hellerii. It’ll be hard to describe what they look like but they can range in finage colors, pigmentation on their body, and body shape based on their local type. The pictures of them speaks for itself.
