Xiphophorus pygmaeus Hubbs & Gordon, 1943

保育: Xiphophorus pygmaeus 由国际自然保护联盟（IUCN）在濒危物种红色名录中为自然保育而进行了评估 evaluated (DD) 数据缺乏（Data deficient） (2018). Although the Huichihuayan and Axtla rivers carry enough flow and most areas remain in very good shape, with some remaining pristine areas, increasing deforestation, pesticides and fertilizers use, and pollution (particularly around Huichihuayan) are common problems that affect them and have to be resolved, particularly given human population increase in the area. During the past years, I have seen an increase in the amount of green algae in the rivers, which was rare before.
