gregariously meaning in Chinese

群居地.合群地

Now , as i watch my fish in their aquarium , they often swim gregariously in groups with their own species , seem to enjoy chasing one another and frolicking in the water , and mind you , even welcome the hand that feeds them
现在，我经常看到他们在自己的小天地里成群结队地游来游去同种类的鱼会结为一群，互相追逐嬉戏，似乎过得很快活。他们也会注意到我的存在，当我要喂食时，他们甚至会游过来迎接我的手。
