The different populations have been tested for aggressive behaviour in groups of four to eight animals of both sexes in tanks ranging from 251 to 9501. In darkness less aggressive behaviour has been observed with the help of an infrared video-camera in the epigean fish and the eyed Micos cave fish. The strongest degree of reduction in aggressive behaviour is shown by the totally blind populations. The aggressiveness increases in the epigean fish as soon as space and food supply diminish.
已在容积从251升至950升的水槽中，对不同种群的四至八只雌雄动物组成的群体进行攻击行为测试。在黑暗环境中，借助红外摄像机观察到，地表鱼类和有眼的米科斯洞穴鱼的攻击行为较少。完全失明的种群表现出攻击行为减少的程度最强。一旦空间和食物供应减少，地表鱼类的攻击性就会增强。
