Xiphophorus continens, also known as El Quince swordfish, is a live bearing fish in the Poeciliidae family.[1] Its holotypes were found in Mexico.[2] Its name comes from the Greek conto, meaning short, and Latin ensis, meanin "sword". due to the species' sword size in males.

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.
