Maturity: Lm 2.5 range ? - ? cm
Max length : 3.8 cm SL 雄魚/尚未辨別雌雄; (Ref. 41236)
脊椎骨: 31 - 32. Five uniformly, pigmented, horizontal stripes on the side of the body, all extending onto the end of caudal fin rays. Anal fin distinctively striped. Lateral line absent. Rostral barbels extend to anterior margin of orbit; maxillary barbels end at about middle of opercle. Branched anal fin rays 10-12. Vertebrae 31-32.
五均勻地，著色又水平的斑紋在身體，所有的延伸到尾鰭末端鰭條側邊上。 臀鰭特殊有斑紋。 側線不存在。 嘴的觸鬚延伸到眼窩的前緣; 上頜骨觸鬚於大約鰓蓋的中央結束。 分枝的臀鰭棘條 10-12. 脊椎骨 31-32.
Adults inhabit streams, canals, ditches, ponds and beels (Ref. 1479). Occur in slow-moving to stagnant standing water bodies, particularly rice-fields (Ref. 4832); and lower reaches of streams (Ref. 58912). Common in rivulets at foot hills (Ref. 41236). Feed on worms and small crustaceans (Ref. 7020); also on insect larvae. Breed all year round (Ref. 58913). Appears to be primarily an annual species in the wild, the spawning season starting just before the onset of the monsoon (Ref. 72224). Domesticated zebrafish live on average 3.5 years, with oldest individuals surviving up to 5.5 years (Ref. 58923). Spawning is induced by temperature and commences at the onset of the monsoon season (Ref. 58913). Food availability also acts as cue for breeding (Ref. 58913). Growth rate is a vital guiding environmental factor for sexual differentiation for this species as observed in a study (Ref. 58948). In this same study, frequency and amount of food prior to and throughout gonadal differentiation period resulted in more individuals differentiating to become females and is more pronounced in hybrid than pure bred groups (Ref. 58948). Often used for mosquito control (Ref 6351). Popular for aquarium purposes (Ref. 44325). Used as a model system (=organism) for developmental biology (Ref. 47810). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).

Life cycle and mating behavior

Breed all year round (Ref. 58931). From Johnson (1932), 'a female never extrudes eggs during active courtship until the genital organ comes in contact with that of the male, whereupon a small stream of eggs is ejected' (Ref. 205). Violent dashing and chasing characterise courtship finally culminating in eggs being shed a few at a time, settling freely without adhering to the bottom surface (Ref. 205).亞洲: 巴基斯坦，印度，孟加拉，尼泊爾與緬甸.(參考文獻 41236) 記錄來自不丹了。 (參考文獻 40882) 出現在哥倫比亞水域可能是從一個水族設備脫逃.(參考文獻 1739)
