Obligate air-breathing (Ref. 126274); Inhabits swamps (Ref. 11225). During the rainy season, adults consume a great quantity of chironomids associated with detritus. During the dry season, they feed mostly on terrestrial insects, micro-crustaceans, aquatic Diptera, and detritus. Absorbs a great quantity of anaerobic bacteria from the substrate (Ref. 27188). First reproduction occurs after one year (Ref. 35381). Used to be cultured commercially in Guyana (Ref. 7306). Cultured in Trinidad on a semi-commercial scale (Ref. 11225).
栖息于沼泽。 (参考文献 11225) 在雨季的时候，成鱼消费被伴随着碎屑的宝刀鱼的大量。 在乾季的时候，他们大部分吃陆栖的昆虫，细小的甲壳动物，水生的双翅类，与碎屑。 吸收没有空气而能生活细菌从底部的大量。 (参考文献 27188) 第一个繁殖在一年之后出现。 (参考文献 35381) 在圭亚那用于商业性地养殖了。 (参考文献 7306) 养殖在一个半-商业的鳞片上的特立尼达和多巴哥中了。 (参考文献 11225)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Reproduction begins with the rainy season (December-January). The male, at times helped by the female, builds a nest made of a cluster of mucus bubbles and vegetal matter. Responding to a nuptial parade, the female lays down her eggs (5,000 to 20,000, measuring1.8 mm in diameter) which are fertilized by sprinkling sperm previously collected in her mouth. The male guards the eggs during incubation and becomes very aggressive (Ref. 35381).南美洲: 阿根廷布宜諾斯艾利斯大多數 Cis-安第斯山脈南美洲河流域北方。
