Behavioral response experiment of fish to mirror images is one of the main ways to test the social and aggressive behavior. The behavior changes of Zrbrafish Danio rerio in tanks contain different number of mirrors was tested in this study. The result indicated that the latency of zebrafish from entry tank which contains mirrors to start moving ( P < 0.05) and their frequency of midline crossing ( P < 0.001) were all lower than control group (contains no mirror), and decreased with increasing numbers of mirrors. The total swimming time of zebrafish in tank contains mirrors increased with increasing numbers of mirrors and significantly higher than control group ( P < 0.001). Additionally, the time spent of zebrafish in side that contains mirrors significantly higher than the reverse side ( P < 0.05), and this difference degree increased with increasing numbers of mirrors.
