生物学特性     字汇 (例如 epibenthic)

Found in shallow and sheltered waters of swampy bays. Generally restricted to shallow waters where they may be found in various habitats such as over sand, rock or, less frequently, in aquatic weed beds (Ref. 13337). Common in shallow vegetated areas (Ref. 4967). Also found in large rivers and floodplain pans and lagoons. Feeds on insects, tiny fishes, vegetable matters (Ref. 5595) and crustaceans (Ref. 13337). Main predator is the tigerfish (Ref. 7248). Breeds in summer, migrating to spawning sites after rains. Migrates to tributary rivers and floodplains when the rivers come down in spate (Ref. 13337). Known to mass at river mouths while waiting for suitable conditions to trigger off the breeding migrations upstream (Ref. 13337). Used as live bait for tigerfish and large catfish (Ref. 13337). Affinities: B. carolinae, with lateral stripe; B. nigricauda with wide black margin on caudal fin.

发现于浅滩与沼泽海湾的有遮蔽的水域了。 通常局限于浅水域了在哪里它们可能被发现于各种不同的栖息地例如沙子之上,岩石或, 更不时常, 在水生的杂草丛中.(参考文献 13337) 常见于水浅的有植物生长的区域。 (参考文献 4967) 也发现于大河与洪泛区洼地与泻湖。 吃昆虫,极小的鱼,植物 (参考文献 5595) 与甲壳动物。 (参考文献 13337) 主要的掠食者是虎鱼。 (参考文献 7248) 繁殖于夏天, 洄游至产卵区被下雨后。 当河在泛滥中下来的时候,回游到支流的河与洪泛区。 (参考文献 13337) 当等候适当的环境时候,已知了在河口的团引起外海的向上游的繁殖回游.(参考文献 13337) 被当作活饵使用对于虎鱼与大的鲶鱼.(参考文献 13337) 分类相关: B. carolinae, ,侧面的斑纹; B. nigricauda 有宽的在尾鳍上的黑色的边缘。
