Description

Alvarez's swordtail is a livebearer (Poeciliidae) from the Usumacinta drainage in Central America. The species is small and yellow-green with a blue sheen; adult males bear an elongated lower caudal ray projecting as a 'sword', characteristic of the swordtails. It lives in clear, fast-flowing water of rivers and streams. As an omnivore it feeds on algae, small zooplankton and insect larvae. The female bears live young. It is popular in the aquarium hobby and is harmless to humans.
