型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 15-17; 臀棘 0; 臀鰭軟條: 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).
