Xiphophorus continens, also known as El Quince swordtail or short-sword platyfish, is a live-bearing freshwater fish in the family Poeciliidae.[2] It is endemic to the Pánuco River basin in east-central Mexico.[3] Its name comes from the Greek conto, meaning short, and Latin ensis, meaning "sword". due to the species' sword size in males.[2]

Description

X. continens reaches up to 3.5 cm (1.4 in) in total length.[3] It is a small, slender species, with a slender caudal peduncle and with a midlateral stripe. The maximum length of the sword is 1 mm (0.04 in). It has a hook on its gonopodium; distal serrae; its grave spot, when present, is only visible under 10X magnification; no xanthophore or pterinophore pigment patterns.[2]
