简单描述

背的软条 (总数) : 8 - 11; 臀鳍软条: 21 - 25. Distinguished from all other species of Oryzias by the unique black nuptial coloration of the adults males. Differs further by having slightly emarginate caudal fin (shared only with O. matanensis which has 40-47 scales in lateral row and O. orthognathus which has 45-54 scales in lateral row), 34-37 scales in lateral row, 8-11 dorsal rays and 21-25 anal rays (Ref. 26747).
与所有的其他种的 Oryzias 区分了藉由成鱼雄性的独特黑色求偶颜色。 不同进一步在侧面的列中借着具有边缘微凹尾鳍 , 34-37个鳞片, 8-11个背鳍鳍条与 21-25个臀鳍鳍条.(参考文献 26747)
Non-annual breeder. Is difficult to maintain in aquarium (Ref. 27139).
