Description

The Montezuma Swordtail has an elongated and laterally compressed body. Males are distinguished by a long lower extension of the caudal fin, called a sword, which can reach the length of the body. The base coloration is silvery-grey with bluish reflections and a dark lateral stripe. Females are duller and lack the sword. It is an active, schooling fish that lives in groups. It is known for its ability to hybridize with other Xiphophorus species. In aquariums, it is easy to keep and breeds quickly.
