生物学特性     字汇 (例如 epibenthic)

Occurs in swamps. Well-adapted to hypoxic environments, being able to survive for hours, emerged. Adults feed on small fishes, arthropods, worms and sometimes on fruits (Ref. 35381). The spiny structure of the pectoral fins enables the male to hold the females during mating (internal fertilization). Sperm can be kept in the female's genital tract for several months, owing to a gelatinous emission from the seminal vesicle of the male. At maturity, the size of the adhesive eggs (20% of the female's weight) is 3 mm. Nine days after hatching, alevin size is 1.5 cm and they feed on microscopic worms or small insects. At around 11 days, their negative phototropism pushes them to hide themselves under branches or rocks. Its pink flesh is highly appreciated by the local population (Ref. 27188).

出现于沼泽。 对缺氧的环境适应很好, 存在能存活长达数小时之久,浮现。 胸鳍的刺状结构使雄鱼能够在交配 (体内受精) 的时候捉住雌性。 精液能被保存于母鱼的生殖道好几个月,由于凝胶状的发射从雄鱼的精液小囊。 成熟时,聚集在一起卵 (20% 的母鱼重量) 的大小是 3 mm 。 九天在孵化之后,刚孵化的小鱼大小是 1.5 公分,而且他们吃微小的蠕虫或小的昆虫。 在大约 11 天,他们的背光性逼迫他们在分支或岩石下面隐藏他们自己。 成鱼吃小鱼,节肢动物,蠕虫与有时在果实上.(参考文献 35381) 它的粉红肉是获得高度地赏识的地方族群。 (参考文献 27188)
