This study is aimed to understand the reproductive behavior, larval culture of Salarias fasciatus . Besides, we hope the result of the study can reduce the trade of wild fish in the ornamental fish market in the future. The results showed these adhesive demersal eggs are white to yellow and ellipsoidal, and were about 0.91 ± 0.06 mm（Mean ± SD） in total length . The yolks were about 3.46 ± 0.05 mm long and contained several oil droplets with diameters ranging from 0.32 ± 0.02 mm and the newly hatched larvae were about 2.86 ± 0.12 mm in length. Parental care behaviors for the ovum occurred after spawning to hatching and it indicates that parental behavior is mainly carried out by males. Incubation period was approximately 106 h at the water temperature of 28 ± 1 ℃. The biological feedings for Blue Devil at initial larvae stage was ciliate, rotifer and copepod. Microalgae was added to stabilize water quality and to nourish rotifers. The supply of feedings should be applied at the same time. Under heat stress experiments, blue devil was caused to die at 37.2 ℃, and all fish die when the temperature reached to 38.5 ℃. In the low temperature tolerance test, fish cause to die at 15.1 ℃ and all fish die at 13.2 ℃.
