保育: Poecilia formosa 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 (LC) 无危(Least Concern) (2019). Listed as Least Concern given the large range of this species spanning from The Rio Bravo basin southward to Laguna Tampamachoco near Tuxpan, the large number of subpopulations, and the lack of major threats. The trend over the past 10 years or three generations is uncertain but likely relatively stable, or the species may be declining but not fast enough to qualify for any of the threatened categories (NatureServe et al., 2019).
