GBIF currently lists 7 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Habits
In habitats characterized by submerged aquatic vegetation and muddy bottoms, Limia nigrofasciata is found alongside congeners L. Islai, L. Garnieri, L. Miragoanensis, and L. Immaculata. Fellow poeciliid Humpbacked limia, and the cichlids Nandopsis haitiensis, Oreochromis aureus, and Tilapia rendali (the latter two being introduced species). In contrast to its sister species, L. Islai (that is often mislabelled as L. Nigrofasciata), the reproductive behavior of Limia nigrofasciata features an elaborate courtship display by the males, that try to attract the females by presenting a large, ornamented dorsal fin, wagging their tail, and performing lateral displays.
In crisis
Limia nigrofasciata is a critically endangered species.
