Found in a wide variety of habitats, most abundantly in well vegetated small channels, ponds and small lakes (Ref. 59043). Adults occur in cool running water. Feed on small insects, fish and fish eggs (Ref. 30578), and plant material (Ref. 59043). Usually breed in habitats with still or very slow-flowing water (Ref. 59043). Females spawn 3-4 times in a season (Ref. 59043). Males clear the surface of the spawning site and guard the eggs until they hatch (Ref. 59043). Regarded as pest which competes with the fry of other species due to its high reproductive rate (Ref. 1739).

成魚出現在冷的流動水。捕食小的昆蟲，魚與魚卵。 (參考文獻 30578) 被認為與其他種的魚苗競爭的有害之物.由於它的生殖率高.(參考文獻 1739)

Nests under stones and the male cleans the cavity with its pearl organs. Eggs adhere to the ceiling of the cavity. The male leaves the nest before the eggs hatch. Females spawn 3-4 times during a season (Ref. 59043).亞洲: 日本南部與中部，台灣，韓國，中國，阿穆爾河流域。引進了歐洲各地與亞洲 (參考文獻 1739) 而且現在出現於聶伯河，第聶伯河，多瑙河流域，斯庫台利湖與普雷帕斯湖與希臘的 Aliakmon 河中。 (參考文獻 26334) 引入後的一些國家報告不利的生態衝擊。也在伊朗與土庫曼引入。 (參考文獻 39702)
