Redfin killifish
Nothobranchius rubripinnis
Redfin killifish is a killifish in the family Nothobranchiidae (order Cyprinodontiformes) — Nothobranchius rubripinnis, recorded as Endangered and tied to Tanzania and Japan.
The killifish
African killifish in this family occupy seasonal pools and forest streams. Annual species bury eggs before the pool dies.
Killifish, livebearers, and splitfins — small-bodied freshwater fishes, many of them from a single lake, spring, or seasonal pool.
Range and habitat
Its natural habitats are rivers and rice fields.
GBIF currently lists 26 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.
Breeding
Small desert or forest fishes in this order live in water that can vanish. The egg bank, if there is one, is the only reserve.
