Facultative air-breathing in the genus (Ref. 126274); Lives in rocky areas and vegetated margins of lakes and streams (Ref. 5259), primarily in lakes preferring still or gently flowing waters (Ref. 51290, 44894). Adults prefer the shelter provided by complex habitats such as rocky lake shores and also in-lake macrophytes beds and marsh habitats (Ref. 51290). Juveniles occur in the water column until 4-5 months of age (40 mm in length) and then move inshore seeking shelter and larger prey items (Ref. 51290). Shoaling in open water when young (Ref. 44894). Feeds on insects, insect larvae and crustaceans (Ref. 5259, 44894) and mollusks with cannibalism of eggs and juvenile fish being common (Ref. 51290, 44894). Breeds in early spring among rocks in the shallows (Ref. 44894). Most fish live for 3-4 years with some reaching over 6 years of age (Ref. 51290).
生活在湖泊與溪流 (參考文獻 5259) 的岩石區與長滿植物邊緣, 主要地在偏愛靜止或逐漸流動的水域的湖中.(參考文獻 51290) ) 成魚偏愛由複雜棲息地提供是例如岩石的湖岸的庇護所以及在-湖大型植物床與濕地棲息地.(參考文獻 51290) 稚魚出現在水團直到年齡 (40 mm 長) 的 4-5 個月然後向海岸移動尋找庇護所與較大的獵物項目.(參考文獻 51290) 吃昆蟲, 昆蟲幼生與甲殼動物 (參考文獻 5259) ，而且軟體動物嗜食同類的普遍的卵與幼年的魚。 (參考文獻 51290) 大多數的魚活到 3-4 年有一些達到超過 6 歲.(參考文獻 51290)
