Ochrona: Xiphophorus continens jest wpisany prez Międzynarodową Unię Ochrony Przyrody na Czerwoną Listę Zagrożonych Gatunków IUCN jako (DD) Brak danych (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.
