The Sheepshead swordtail (Xiphophorus birchmanni) is a freshwater fish of the family Poeciliidae that grows up to 7 cm.
Description
Birchmann's swordtail is a livebearing toothcarp (Poeciliidae) from clear, flowing rivers of eastern Mexico. The species grows to about 5 cm and has a stocky, yellow-brown body with dark crossbars and, in the male, a high dorsal fin; unlike many relatives it lacks the sword-like tail extension. The male fertilises the female internally, after which live young are born. It eats algae, insect larvae and small invertebrates. The fish is harmless to humans.
