Compact, laterally compressed body with a rounded fan-shaped tail. This specimen displays a 'sunset' or golden-orange coloration. They possess a broad dorsal fin and a slightly upturned mouth adapted for surface feeding. Sexual dimorphism is present; males have a modified anal fin called a gonopodium.

Habitat & Distribution

Native to Central and North America, specifically from Mexico to Belize. They inhabit slow-moving or standing waters such as ditches, canals, springs, and swamps with dense vegetation and typically shallow depths.

Size & Weight

Typically reaches 1.5 to 2.5 inches (4 to 6 cm) in length. They are lightweight, small fish, usually weighing only a few grams.

Similar Looking Species

Green Swordtail (Xiphophorus hellerii), which is larger and males possess a long tail extension; and the Southern Platy (Xiphophorus variatus), which has a more elongated body and different fin proportions.

Ecological Role

Omnivorous surface feeders that consume small insects, crustaceans, and algae. They serve as an important food source for larger aquatic predators and birds. Conservation status is 'Not Evaluated' by the IUCN, but they are highly common due to extensive commercial breeding.
