Xiphophorus couchianus (Girard, 1859)

Conservación: Xiphophorus couchianus es evaluada por la Unión Internacional para la Conservación de la Naturaleza en la lista roja de especies amenazadas como (EW) Extinto en la naturaleza (2018). The species was lost by habitat loss and degradation caused by urban encroachment, sewage pollution, desiccation of the natural springs and competition and predation from introduced invasive alien species (Ceballos et al., 2016). Ojo de Agua de Apodaca has been transformed into an urban recreational pool and the remaining population there has been lost.
