Phallichthys is a genus of poeciliids native to Central America. They are hardy fish which inhabit stagnant and slow-flowing waters, making them well-suited to fishkeeping.
==Etymology== The genus name Phallichthys comes from the Ancient Greek φαλλός (phallós), meaning "penis", and ἰχθύς (ikhthús), meaning "fish", referring to the "comparatively huge" gonopodium, the modified anal fin used for copulation. The common name for P. amates, the merry widow, is sometimes applied to other species in the genus as well.
