Max length : 5.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 122075); 5.3 cm SL (female)
背棘 (总数) : 0; 背的软条 (总数) : 15 - 17; 臀棘: 0; 臀鳍软条: 16 - 19; 脊椎骨: 30 - 32. Diagnosis: Distinguished from all congeners by the combination of the following character states: caudal fin red with black posterior margin in males, narrow white margin to dorsal and anal fins, and silver iris; posterior portion of flank and unpaired fins with black spots in females; pre-dorsal length in males 62.4-65.1% of standard length; 5 + 15-16 gill-rakers on first branchial arch; 29-31 scales in longitudinal series; 16-18 series of scales around caudal peduncle; two longitudinal rows of scales between anterior supraorbital series of neuromasts; anterior supraorbital series of neuromasts arranged continuously, with four well-developed neuromasts; four neuromasts in posterior supraorbital series; 29-31 caudal-fin rays; 30-31 vertebrae; second proximal radial of dorsal fin between neural spines of 13th and 15th vertebrae (Ref. 83514, 122075). This species differs from Nothobranchius lucius in having a plain red caudal fin with narrow margin at the upper and lower corners in male (Ref. 83514).
Found in temporary pools in floodplains, rice fields, swamps, ditches and small streams (Ref. 3788). Found in water-filled depressions in floodplains of rivers; with vegetation often near edges, usually grasses; occasionally grasses cover the entire pool; if aquatic vegetation is present, it may comprise of Nymphea, Ottelia, Lagarosiphon, and Utricularia species; annual species; eggs deposited in substrate where they survive dry season; hatching at onset of wet season; rapid growth of fry; sexual maturity may be attained in six weeks; may be associated with other annual or non-annual fish species (Ref. 83514). Bottom spawner; 4 months incubation; difficult to maintain in aquarium (Ref. 27139).
在洪泛区，稻田，沼泽, 沟渠与小的溪流中出现于暂时的水池。 (参考文献 3788) 底部产卵鱼， 4 个月孵育时间。 在水族馆是难以维持。 (参考文献 27139)
