保育: Xiphophorus continens 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） (2019). Although the area of distribution of X. continens is preserved in relatively good condition, mainly by its remoteness, given its small extension it is prone to suffer alterations by further deforestation around the main spring — recently its eastern part has been deforested for agriculture, as well as the introduction of exotic species, common now in other areas of the Pánuco. In recent years, Poeciliopsis gracilis has been introduced to some areas of the Gallinas River, in my estimation causing a decrease in the numbers of Poecilia mexicana.
