Original description as Apistogramma elizabethae:

Conservation: Apistogramma elizabethae is not evaluated by the international union for the conservation of nature in the iucn red list of threatened species. Considering the remoteness of its distribution, Apistogramma elizabethae and its sympatric species should remain safe in the near future; what remains to be determined is the impact of the collections of wild specimens for the hobby on some of the most sought-after populations.
