Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); sagittae: The species name sagittae comes from the Latin sagittae meaning arrow; in reference to the relatively pointed head and slender shape (Ref. 98818).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic. Tropical
Africa: seasonal pools and swamps in Ruwana, Grumeti and Mbalageti river systems, Lake Victoria basin in Tanzania (Ref. 98818).

Morphology | Morphometrics
soft rays: 15 - 18. Diagnosis: Nothobranchius sagittae is distinguished from all other members of the Nothobranchius neumanni species group by the following combination of characters: in the male, a relatively elongate body shape, a dorsal profile that is slightly convex, a concave transition between the head and body, a pointed snout, and an upward-directed mouth cleft; the anal fin in the male is red with one or two pale yellow, white or blue-white horizontal bands, a light blue-gray proximal part, and a distinct dark red margin; the caudal fin in the male is usually completely red with a relatively dark marginal band (Ref. 98818).
Occurs in shallow, seasonal pools and swamps (Ref. 98818).
