The Green Swordtail is a platyfish native to well-vegetated swift-flowing streams and still canals/springs from Mexico to Honduras in Central America. Platyfish are live-bearers and the thick vegetation is important for the young fry to hide. The wild form is olive green with an orange patch on the back and orange lateral stripe; the male develops a black-bordered greenish yellow "sword" of the lower caudal fin after which the fish is named. Males grow to 14cm long and females to 16cm.

The Green Swordtail is a nuisance invasive species in several parts of the world to which it has been introduced, out-competing native fish for food and habitat. In captivity it has been hybridised with the Southern Platyfish, X. maculatus, and bred in different colours and patterns. The Pineapple Swordtail above may be one such hybrid; others are red or black, speckled or striped.
