簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 14-16; 臀棘 0; 臀鰭軟條: 14 - 16. Diagnosis: Nothobranchius venustus belongs to the N. ugandensis species group presenting the following combination of characters in males: body colouration light blue with red or red-brown scale margins; frontal part of head red-brown and throat light blue or red; caudal fin uniform red; anal fin light blue or yellow with red-brown spotted pattern (Ref. 123150). Nothobranchius venustus differs from all other members of the N. ugandensis species group by a dorsal fin with a narrow light blue subdistal band and a narrow red-brown to black distal band; an anal fin light blue with irregular red-brown stripes perpendicular to fin rays proximally and medially; and orange with red-brown stripes parallel to fin rays in distal zone; and a dorsal-fin base length 20.4-23.2% of standard length vs. 23.4-28.7% (Ref. 123150).
Found in a temporary pool about 10 m wide, more than 20 m long, and about 1 m at the deepest point; the water was turbid, the bottom of the pool not visible (Ref. 123150).
